K&N Air Filter
 

I couldn't find anything so I made this thread


Has anyone put only a K&N air filter in their BRZ and what performance differences did you experience?

First day I got the car, K&N Filter.

Did it do anything? ...Eh, better throttle response and slight better sound.

Cool, I'm going to install one maybe next month.

Get a inlet tube as well!

I put the K&N filter on my car and gained 38whp and 80torques!!!! Dyno proven. No joke, it was nuts, we tried it on 14 different dynos and the drop in filter made it so you nearly pealed your face off when you mash the throttle!

BEEEHHOOOLLLD, THY MIGHTY K&N FILTAHHH!!!!!!!!!!!!!!!!!!!! :lol:

Just ordered one!!

I installed one at 2500 miles. Better sound and slightly noticeable power boost. There's a thread on the forums here comparing 3 different ones and their dynos

I haven't noticed any difference.

just install a new intake, way better just change the air filter....it makes much more difference.

Actually, in most modern cars, extensive flow testing is done on the intake system to meet a wide variety of flow demands. A drop in filter is the best solution to allow more flow while still maintaining the optimal flow pattern as designed.

I hear a lot of talk about the intake not being loud enough and people cutting off and removing the stock intakes resonators. They want to make the intake louder, well, sound is air pressure. Thats air pressure thats not going into your intake. The resonators work to keep the air pressure optimal. The sound generation tube is what allows you to hear the sound of the throttle body from the intake without compromising the flow in any direction.

I just got the car like 2 months ago, I am absolutely not taking major components apart just to get some extra power I'm not dying for. I'm planning on the K&N so the engine can breathe better, sure it will make it the slightest bit quicker but I'm not concerned with that. With most new cars, if you look at it wrong the warranty get voided. Sometimes I feel like Cameron Frye. " It could get wrecked, stolen, scratched, breathed on wrong... a pigeon could shit on it! Who knows?"

I put a K&N filter in a week ago. I don't notice much difference.. maybe a little different sound and perhaps a little more throttle response at high rpms. It was worth the $40.. but no miracle as far as I'm concerned.

He said K&N. Not Works.

AEM intake system uses K&N Filter but includes a tune for the maf and deletes sound tube. only intake worth a look imo.

With the Unichip and the right map, car ran very smoothly withvery good throttle response and feel with just a K&N panel filter. Without the Unichip it still made a difference. You hear a lot of crap about K&N and they take a lot of fire for their products, but when you read independent comparison tests (hard to find ones that don't have a biased slant BTW) they work well and are reliable. The dirtier they get, the better they work.

I bought the trd air filter and it was ok! But when i replaced it with a k&n one, i notice the difference. The engine breathes better, sounds better and better performance. And under normal speeds, a slight better gas milage.

If you seriously cant find any information on a drop in filter your not trying hard enough. Why dont you try using the search feature and search drop in filters. Tons of threads on this subject. All drop in filters are the same just pick one from a company you prefer. Almost all types of drop ins will perform the same as company a and b. Only if it is a drop in that isnt oiled will it not do as well as an oiled filter but 1 more whp from an oiled filter isn't worth the hassle of oiling and worrying about over oiling the filter messing up the MAF.

Cleaning up is a hassle where as a dry reusable it is much easier to clean up and re use. Of all the drop ins though I dont like K & N. I prefer to support the smaller companies who made a name for themselves by making quality products. K & N is already well known help out the vendors who arent as big of an operation but still offer quality products.

Just echoing the others here. Installed my K&N filter last week (the car had a little over 700 miles on it so the OEM filter was still clean). I haven't noticed a difference in performance but to me it sounds a little less raspy with a bit more growl when revving.

The thread is from march.

Trd filter wasn't impressive? I thought k and n actually made the trd filter and toyota sold it as its own. What was the difference in make and quality and performance?

I did a perrin intake tube and a K&N at the same time. Car has a little more "pep" with the car. Throttle response is better too. If you are looking for bit gains, this isn't it, but worth the money IMHO.

I recently upgraded to a K&N drop-in. First time I got on the throttle, I threw a rod.

I really should have done supporting mods first.

I am sensing sarcasm? :eyebulge:

No, he is serious, K&N filter is only safe with a tune.

It's just a less restrictive air filter. How can you throw a rod with it?
It isn't even like the TRD CAI which doesn't need a tube either

That's totally right - and most people don't know that the additional airflow of the K&N requires fuel enrichment, so you need to buy larger injectors and a new fuel pump to support the additional air flow.






:bonk:

And yet not so with the TRD CAI?

THEY ARE F***** With you

lol, apologies, sometimes I can't resist yanking chains, especially when there are so many other threads to search.

K&N, AFE, etc. etc. all those air filters, not going to see much difference on these motors, you're not going to really feel any difference. Let me put it this way: wake up early in the morning, 55 degrees out, drive your car with stock filter. Then switch to K&N filter in the afternoon, 75 degrees out. You will feel a bigger difference from the temperature variance than the filter change (i.e. your car with stock filter in the morning will probably feel faster) - so buy an aftermarket drop in filter if you want a cleanable/re-useable filter, not because you want more power.

I was starting to wonder. Definitely didn't sound right that a simple filter would Jack up these engines.

I know there won't be much gains, it's for the longer usability than paper crap filters.

The better CAI systems do reportedly increase HP, not a huge amount and might be 'feelable', thought it not huge gains. Regardless of what you do, you won't max out the stock fuel system unless you go FI.

From what I've heard, the CAI only seems to increase throttle response in the low end. Something I think this car suffers
