Which one of these two air filter are better? Works drop in air filter is cheaper than k&n. But which one is better ?

Both were drop in air filter.

OEM filter thats changed regularly. better then both

OEM air filter better than them in term of???

OEM air filter better than them in term of???

Probably no significant difference if drop-in filters. I just chose the cheaper one.

Sorry to hijack the thread. But would like to ask for you guys opinion about redline drop in filter for my iswara. Are they any good? Any significant difference with k&n filter?

drop-in filters doesn't really make any difference. If you notice any difference then it's probably psychological. The only reason to use drop-ins like k&n and redline is they are re-usable and each clean can last up to 40k km. As opposed to cheap filters...only last 10-15k km.

If you really want performance, then get open pod filters. Then again, open pod filters are more expensive and gain very little power. It's more for those who want to mod their car every little bit for performance.

if open pod, i am sworn by AEM dry element. say no more to oily wet element on K&N.

im using it, the difference isn't exactly huge nor do i have dyno to prove anything.

i would say though i like the air intake sound (despite being a carbie drop in rofl) that is louder as you approach red line and if anything, you create less waste as the filter usage is permanent (only need to buy their cleaning/re-charger kit)

oh you get cool k&n vinyls/stickers for your dull looking ufo carb lo

Yeah the excess oil might affect the AFS in the long run.
Long time ago I also read a comparison review which ended up recommending APEXi as the best among other popular filters, and it's also dry cloth type. Just need to be careful when buying cuz got lots of fakes nowadays.

Little to zero differences.

Wow yours is UFO style. What a classic. Is it magma engine?

Here is my opinion on air filter. Drop in air filter provide little or no improvement at all. I've dyno my car at 61-62 whp with K&N air drop in air filter only. Stock as provided by proton spec is 77bhp. So can say is near zero hp improvement if you add in fluctuation.

As for the open pod also same little to no improvement. Only they provide nice suction sound unless your car is heavily moded.

As for the dirt of course it is more dirty than stock paper but for everyday ride in malaysia road it is little to no difference also. Last time I use paper filter also never get dirty except for the haze time where my stock paper filter get dirtied very fast. So try to imagine how much would the dust actually enter your engine. We are not in test environment so there is little chance for your car to suck in so much dirt unless you live in kampung in dusty road. If you still scare the dirt than change your engine oil as frequent as possible.

The plus point of aftermarket air filter (oil/ wash type).
1) Save environment as no need replace for 10 years.
2) Maybe save a bit of fuel. Didn't test this point but i feel my car doesn't consume much fuel at all.

yeah magma 12v, expensive some more because carb filter element is much larger than regular boxed drop ins

only bought mine cuz got 20% off from eneos promotion LOL

I thought magma is 8v never thought got 12v. Mine is megavalve 12v carb. I use drop in instead of ufo.

A lot of users ask this question online or in this forum. The logic is very simple. Let me summarize what I have found out:

1) Paper filter is still a paper filter. Drop-in filter is still a drop-in filter. It is just a filter, not because of a tiny item that it can make the car wonder. Many people do think in this way. Will I change 1 tyre or 4 tyres then my car becomes super car? The answer is no. If someone change the drop-in filter, how much the hp gain? Let's say 1-5 hp. Is that (at most, psychologically) 5 hp significant? In fact, the hp gained is much much lesser than what is expected.

2) Back to material of the drop-in filter. Drop in filter using those reusable materials, something like mesh. The way the drop-in filter works is to apply oil on it, by increasing the surface area, hoping and trying to capture as many particles/dust in the air. Now there are 2 problems. First one, how often does a user forget to clean and service the drop-in filter? Remember it only works if being serviced often. Secondly, since it is like a fiber mesh, the cavities are big enough to let some fine particles or dust to escape into the throttle body. This will make the throttle body dirty easily.

3) Then people tend to dissatisfy, asking why these drop-in filters are so popular. First of all, it is all about business. When these people would like to make business, they would think of a way to convince the consumers. They have all the resources to bring their items to whatever laboratory to come out with test reports to supports their claims. Does these true? Anybody with some understanding how these laboratory tests would understand how these works. They can spend big money just to make their items sell!

4) Again, back to the previous points, still a default O-Lee-ginel Brand Paper filter is the best. If feel pocket got money, just buy a dozen, keep at home, change every 10k, then you will realize it is much more better than those sophisticated drop-in filter!

Do not need to thank me, thank online warriors!

hmm could be the megavalve, sticker on the engine long worn off so i forgotten. generally remember the engine code which is 4g15p

but yea, old UFO carburetor (aisan i believe?)

14 years old car

=edit=
hmm, after reading back a bit, i think i may have mistaken UFO for these:


when it should be like these?

K&N is better

Stock is best for filteration.

But if you die2 want to upgrade panel/drop-in filter (which gives very little gain) then K&N is better than Works (rebranded Simota).

If you still insists on cheap brands, then stick to stock.

The debate has always been there is a very simple test that you guys can to see if your car benefits from running with K&N. Just run your car without the air filter and feel the difference. If your ECU is not programmed to take advantage of more air, you will not see any performance gains when running without a filter and therefore no point buying K&N. A short run on a clean road is not going to kill your engine.

What dyno chart fails to show you is the small difference (yes, it's only small..) in throttle response that you get when you run with non-paper filters. Changes like throttle response from 30% to 50% is where you feel the difference. MOst people jump in the car and go all out 100% and say no feel.

Eventually it still comes back to whether your car can cope with the additional air flow. K&N demos have proven the difference in air flow between their filter and paper filter is very apparent. Of course, some grades of paper filter may have more air flow than others but like I said, run your car without an air filter and see if you feel any difference before buying.

staff pun lupa how to link vids

That is because this staff does not post many vids in Lowyat.. I got so used to posting in FB that I used the FB link instead of our own youtube tags.

yeap exactly the same as my experience. while i cannot quantify my throttle response improvement, it certainly makes it easier to perform sudden/on-demand accelerations for overtaking or just simply wanting to speed faster.

and yes i've ran my carb without filter vs proton's ori filter, the difference is there so i figured that K&N's improved air flow (without much compromise in filtration) would benefit me.
the oil/having carb dirtier is also not too huge of a concern since i use 3bond carb/throttle cleaners pretty regularly because i can't stand slow throttle responses anyways

in the end the only thing as i mentioned holding me back was the stupid pricing, which i gave in when it was on 20% discount

hehe fair enough

and i believe certain ECU do take a lil time to adjust to the new amount of airflow received after changing the air filter. Correct me if i'm wrong

to answer ur question TS, between K&N & Works...which one better..i don't know. But i'm using K&N

as for those who said paper filter is better than K&N filter...well i'm sure they never used
K&N filter b4.

price wise probably (rm10/20000km vs rm230/40000km but usable). Not that u can expect a big
increment in HP but i can assure its definitely feels different compared to stock filter

must try all and feels different... but i'm using K&N...

Good topic.

I'm also contemplating in works or k&n.
Works cost Rm 150 while k&n rm 270.
Almost double....

I'm using k&n drop in for my savvy, every 10k, I will clean the filter and oil them without fail.
I won't say there's any improvement, just my engine can breathe better and cleaner.
Hearsay drop in helps in pick up.

wow u very rajin 10k km already service eh? mine i did it every 40k km atleast

go for k&n...works got so many imitation stuff...

haha, i always believe in maintaining the car, in return, it will serve you well.

i'm using amsoil since day 1 for my savvy, from engine to gear to steering..
kinda expensive but really good..
only this recent year, then i begin to cut corners..

somemore my savvy got CAI, so very responsive

agree. long-term investment, and a important thing car is not sitting roadside with emergency lights

Fm my point of view..its a combination factor.it is impossible to gain soooo much power if one just use the replacement air filter.kn or even works will perform better if we consider factor such as;
1. Spark plug.always cx the recommended gap.either standard,iridium,platinum etc..
2.throttle body. Cleaner is better.
3.voltage stabilizer plus grounding cable.
4.silicon cable plug.
Fit these 4 together with kn or works,and you shall feel the different.other things to consider are
1.tyre condition.always adhere to manufacture recomendation.
2.accesorries installed in car.easy to understand.more gadjet installed..more power needed.
And so many other factor to consider.
Kn or work surely will nott make your stock kancil into lancer turbo performance.not in life,not even in a dream.kn or works goal is to give effiency and smoothess.
Proven on my brother's 20 years old proton.smoothess and efficiency that we want.not suddens turbo performance.thats riddicilous.lol.

you searched for a 2 yeard old topic?

Lol..thabks to him caused I'm reading it now haha.
It's an useful info btw.

Lol.yes i did bro.since the thread still open.its never too late right?someone will read it one day.thanks to them.and you too for reading or viewing it.and information never get old bro.its expending.and that what i do.lol.

Thanks for sharing your knowledge

I actually have a few dynos of stock car with stock drop in vs stock car with K&N drop in.

Stock (not very clean) - better torque, lower hp. K&N - lower torque, higher hp. Within 2 to 3nm and 2 to 3hp, that difference alone can also be attributed to error difference.

Pretty much same result for the inspira hehe

Polite way of saying no difference. lol

Aye haha

I've used K&N before and sold it off before letting it slowly damage my engine. If you hold it up against background light, you'll see tiny holes in which fine dirt can go through. The size of the particles that can go through it is enough to cause engine harm.

I've switched to regular paper filter as it traps dirt better and did not notice a drop in performance. This is better long term wise in terms of engine health (piston seals etc). Just keep in mind to change it regularly every 20k-30k km.

Only very minor improvement in term of performance woh. But my ricer friend strongly recommended intake mod, he reckon it's very important like our "nose" lol

not much different la...the best about these air filter is they are washable and reusable..so u save money la...they lasts longer oso if u do proper mentenen the filter

induction sound aje~~

there might be gains if u port the intake and actually tune it properly but how many people actually go so far?

What the first page user mentioned about drop in filter is true and whatever gained is insignificant. The difference is save money if using drop in filter for long run provided user maintain the filter well and willing to accept the fact that drop in filter will not filter off fine particle like stock.There are saying fine particles that enter will not affect the combustion chamber, which I have my reserve. In short, for peace of mind, stock (original is not cheap), for money saving, drop in.

as stated before, try remove your filter and see if got gains. If there is, can try finding for these kinda filters

isn't that right behind the radiator? ohh welp, at least your extractor still has the heat shield

Not my car, got it off another forum But if placed correctly, it might be quite useful

ahh haha icic
placement is VERY important, mines sucking all hot air, haven't got time ever since i got the car to build a box for it

**note that i do like his stuff, twin mushrooms do look good**

This post has been edited by lsm1991: Feb 23 2016, 03:21 PM

I've see people drag the intake all the way and place it next to the extractor

Initial d ryosuke takahashi

I think custm made some cover or box to protect it from sedut hot air is good enough for ordinary car enthusiast.

Imho, I think it's percentage x the horsepower of your engine. The improvement might be much more significant if the hp of engine around 200 something.

I just saw this on youtube and it's somehow related to this topic.. enjoy

Just bought my K&N cheap from EBay, can't wait to see the difference!

Works vs K&N.. buy K&N.

Benefit of K&N.. lifetime.. no need to change.
Cons of K&N.. congrats you are now a ricer.

Not really lifetime. You need to wash and re oil with its kit. Works just require normal wash and dry. Both are not really lifetime as they will gradually wear off overtime. You want lifetime get those aluminum mesh filter.

8 years and counting on my K&N. recharged it, no wear. Got million mile warranty anyway.

The article in the link below has a very clear and concise detail about why OEM stock is better. K&N has definitely benefited from its years of marketing but the facts themselves do not lie. There's a reason why automotive makers use "restrictive" paper filters instead of K&N air filters.

http://www.nicoclub.com/archives/kn-vs-oem-filter.html

Knn with stock airbox

Gains proven by mighty car mods

TS is talking about OEM drop in vs aftermarket drop in. My article talks about OEM vs Aftermarket drop in as well.

Even if it's a cold air intake system, a gain of 3% to 4% is really chum change IMO. But I suppose for a NA car, it's would be clearly felt and is considered fairly impressive.

Still prefer OEM.. just replace every 10k km, the air density let through from OEM is just nice for stock engine..

Unless heavy modifications engine, need higher air density
