Air filter for stock box : K&N or Perrins? - Toyota GR86, 86, FR-S and Subaru BRZ Forum & Owners Community

Just curious which one is better or what do you guys prefer? K&N or Perrins air filters for the stock box.

Whatever fit your budget

i got the K&N but my friend gave me the Perrins so debating should i swap it out.

OEM.

Buuut if I had to pick an aftermarket filter, I'd go Cosworth or A'PEXi.

TRD worked for me : )

Cosworth for me. Definitely better throttle response than stock.

What ever you want, what ever your wallet thinks is best. They all perform the same.
Also depends how much of a germaphobe you are when its time to cleaning the filter.
If you don't want to clean it, get the dry ones.

Like the two posters earlier in the thread, I can offer a third recommendation for the Cosworth drop-in filter. I was initially suspect of any benefit, but now I'm a believer - once installed, the engine revved more freely, had noticeably better throttle response, and sounded better, too. Is it a game changer? No, of course not - but it was a nice improvement for less than $50. Easily recommended.

Since the difference power wise between those two is so minimal personally I would go with the Perrin because it looks cooler.

Mr.ac · 08-19-2016, 02:25 AM

Any performance drop in filter would do the same exact thing. It would sound nice, rev freely, all butt dynos will be the same.
I went with K&N cause 1. It was $45 at Walmart 2. It's pretty much a midget TRD clone. 3. I have K&N filters on my MR2 Turbo with zero problems over the last 10 years.

But, it really was a coin flip from getting the Apex or other dry filters.

So sitting inside the OEM air box, the Perrin drop in filter looks better than other filters? Do you have X-Ray vision?

I went with the AFE pro dry S filter, mainly because I'm not a fan of oiled filters on MAF cars, the dry filters have better filtration, and I've had good luck with their products in the past.
