Is it true that K&N air filter will give better fuel consumption and increase in HP & torque? lol



And what about this "carbon" air filter. Does it do better filtration when in-taking dirty air from outside?



Thought of trying the "carbon" filter. But I don't quite believe what the mechanic said to me, thus need you guys to enlighten me with your experience

carbon is only or odor control that put inside cabin

Many experiment done, yes it does help a bit for NA car, but gets dirty fast and lets more dirt in

i laf..... so funny.... ohwhy

honestly, feel no difference whatsoever... asalkan it lets in enough air... its fine.

i bought K&N because original Honda Air filter a bit expensive, RM80 each and i prefer to change every 10k.


If ur air filter RM20-30 , dont waste ur money to get k&n , juz use and throw ...

my k&n only RM290+, cleaner RM85 .....and i can clean whenever i want . ohya , previous my Honda City 2014 jerk and couldnt find the reason behind. and it was due to dirty air filter ...now no more jerk at all..

and i use Bosch Activated Carbon cabin filter Click Here, RM60 for my Honda City . Reason, my ori Honda filter cost me RM90+ , and its not activated carbon . it does better filtration

Sorry..

Not knocking K&N, but l once read somewhere tat Honda paper filters are actually better at keeping dirt out then this.. thou, if you are talking about better airflow for more power - tats a different story ..

Have you tried it

You mean K&N?

About your K&N, did you feel the power increase ah? Hahaha
Although 10hp no feel.

Yeah, saw that Bosch filter, costs about 40-60 for Vios.
Do you feel any difference with that carbon filter?

If as what you said, cannot feel if its 10hp im dead sure that you cant feel the K&N's differences. because changing of this drop in filter will not increase 10hp. Previously i changed such air filter as well. Pipercross UK. Actually nothing different as well. Slight better response only. But whats right is, very easy to get dirty for ur TB.

my honda city alwaz that powerful when i drive . with my wife and some items in boot.
so i dont think it will give extra power. u want more powerful engine , get more powerful car . dont expect air filter can do wonder...LOL

i donno if got any diff , but i only trust bosch filter. try it especially during haze . u will notice the difference. why pay the same price and get normal cabin filter ?

Activated carbon can do better filtration , thats fact. google for it

yes , disposable filter is alwaz better for dirt filtration ....but its a bit expensive and sometime SC will only ask u to change on every 20-30k km....my 20k filter is so dirty and i cant bare with it.so i change to K&N and clean myself every 8-10k

dont worry about dirty throttle body ....u can get a throttlebody cleaner to clean it every 50-100k km

I know Might Car Mods did a big mythbusting episode on air filters. If I remember correctly, they found that they don't make any difference.

i get k&n to save money on disposable air filter. i didnt expect any increase in performance. if ur air filter only cost u RM20-30 like myvi , dont waste ur money to get k&n...

mine RM80 air filter , and only can last me about 10k-15k km...max 15k km...

K&n

They did find some gains in a NA car , but nothing on a turbo car

really depends on the intake design and all that...

kn filters like ^Ware^wolf said... if you are getting it cause you want long term savings (if it is even saving in the 1st place, kiralah) then yeah sure, otherwise, its a big waste of time.......

cukur noone talk about open pod yet.... that one i will nag over and over

This site does a very good review

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

for my personal experience...
carbon filter do have some pro and con

pro:
better filter and smell

con:
restrict air flow..due to thickness compare to normal

Hm... Does that mean worse FC?

Carbon cabin filter , for air con la ....aiyo..take out ur glove box at passenger side , it's there .it's not air filter at engine there

2 type
1. Air Filter - Engine
2. Cabin Filter / Air Cond Filter / Dust & Pollen Filter - all the same (inside car)

This post has been edited by ^Ware^wolf: Mar 3 2017, 04:19 PM

TS.... why would fc be affected, whats it restricting..... I hope you know that its IN the car... Literally in the car.
Itu carbon filter letak for air circulation kan.... dun crazy letak for the air intake yo!!


just to confirm you are talking about 'cabin' filters right, not the car engine air filter

Only cabin filter got activated carbon type...air filter DOESNT HAVE activated carbon .hahahhahah

Yalah I'm talking about the air intake filter.

So the Bosch you mentioned is for cabin or engine air intake one lol

the bosch i mentioned is for cabin ....


ur 1st photo : K&N air filter
2nd photo : cabin filter

No, I was saying the engine air intake

Btw, the cabin filter is under dashboard one right? Access through the glovebox or some where else? I don't think I've ever changed the cabin filter...

Then I showed the wrong picture lol.

Edit: how often do you changed the cabin filter?

my face... i hit it too hard..... owai

nvmlah atleast ts made me laf

wat car model ? normally inside glovebox.... take out the glovebox and u will see it ....

recommended to change every 10-15k km ...

If your car engine is modified where additional flow is required, yes there is some, but rather minor. And before putting on the aftermarket filters, you'll most likely modify the intake pipes also. If you're driving stock, the improvements is negligible at best, the air temperature will give a more noticeable difference in the "feel" of engine response.

And if you die die want after market filters, please get those that are convenient to just wash with water (eg, AEM dry filters or something similar you can find in the market). Needing to use specific cleaning agents and re-oiling is just not time and cost effective. Also, re-oiling is a mess and you need to know the appropriate level of oil is required, too much will mess with your MAF filter; too little and you lose much more filtering potential. So just really not worth the hassle.

And here is an experiment done to compare aftermarket vs stock air filters :
http://www.nicoclub.com/archives/kn-vs-oem-filter.html

Source
Once K&N filter oil is properly and evenly absorbed through the cotton, no oil will come off, even under extreme engine conditions.

i think this is common sense as well ..

Original Honda air filter (imported from Thailand) can be bought for around RM25 at your local spare parts shop.

checked with several Honda Authorised Spare Parts shop , cheapest RM60 ... im not sure if RM25 is original or not. dont dare to save RM35 on air filter ...LOL

yupe the cabin one...

True, but notice the wording "properly" and "evenly", under oiling it is fine, but over oiling is a definitely probable especially for 1st time users who couldn't understand to wait for the filter to fully wick, and add on if required.

I'm not against K&N or similar brands, but i personally find it a hassle for the need to re-oil and use special cleaning agents. That's why i commented earlier to get those dry type filters which just need a water bath with some normal soap. Some may laud the fact of environmental benefits of not needing to throw away those replaceable OEM filters, but as the data shown in the link i attached, there's no filtration benefit.

Yup.true also .that's why I Google and YouTube first before reoil ..

Ok 1.. I compared the quality between the RM25 filter vs Honda filter. The paper filters are quite thick too. Use 1 year then throw lo..

For our dustier environment, 20k km max throw. If your place really dusty, change it every oil change.

There is no advantage in HP or torque from K&N drop in filter. You can use it if you want a washable and reusable filter but bear in mind that the paper filter does a much better job and it isn't expensive also.

For K&N:
Better FC? No
Increase HP? For normal cars, not noticeable if any.
Better filtration? Not really also.
Is it worth it? Only if your original filter is rather expensive. Even in that case, I only use cheaper Taiwan brand: Works. If you really want a good performance filter, actually the best one is APEXi made in Japan BUT practically cannot find original anymore as all those on sale now are all fakes!

Carbon filter:
I don't know, coz I just used normal original ones as long as cheap!

Recommend to use either ori air filter or better reusable filter .don't use cheap china air filter

Depends, some car the paper filter cost almost rm100. Might as well add abit more for reusable aftermarket

One of the benefit of using washable air filter , can clean it on ur own interval .easy

I always believed those k&n air intake filter can get more torque 😀 zoomzoom !!!

Well might be true but in my case this Works filter works just as good. (I have used K&N before so I have some idea of how they are for comparison). It's not that cheap too actually, just cheaper than K&N or APEXi but still like more than double the original std filter (paid around rm180 over 4 yrs ago). What I would really avoid are fake ones (like fake APEXi), HKS filter or any foam type filter even though original brands, or Blitz stainless mesh filter or similar type, because they do a bad job at filtering.

How u find apexi air filter when the brand is long gone ....

Lol?

ok my bad ... hahahha me outdated d

Got me a K&N for my old Elantra, in addition I also deleted the intake resonator so there's less restriction of airflow. I notice better FC for long distance trips, although don't know which mod does it. I still keep the old paper filter to use as temporary replacement when I need to re-oil the K&N, K&N recommends checking every 40k km.

I bought it shipped from the UK, much cheaper than buying it here.

Drop-in K&N does not give me noticible HP gains on dyno test. However, in real life usage, I feel the throttle responds faster to a jab on the accelerator pedal. Especially for those car which has a slow drive by wire throttle body when you're trying to change lane in a traffic jam.
Well, a lot of people don't like the rough sound from this kind of filter though.

rough sound?

Honestly speaking, if you compare the stock paper air filter to a K&N drop-in , the engine sounds more rough with a stock exhaust system . Perhaps you haven't notice?

Yes , slightly higher noise from stock .

Agreed with the throttle response and the "droning" sound altough in my case the sound is even louder because I removed the resonator, only noticeable at 100++ speed though.
