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.
