K&N Air filter

Wanted turbo noises but couldn\u2019t justify $200-$300. Parts : 3 inch OD - 3 inch OD pipe. K&N 3 inch filter, APR SAI Filter. Drilled a vaccum tap into pipe. Sounds really nice. I know not much gain but sounds good lol.

Pros: sounds really nice
Cons: not much gain

I've had one for years and no issues. Just oil it correctly. Also, watch engineering explained video on it and it does add some power. Not much. And I don't have any mpg gains.

Pros: add some power
Cons: no mpg gains

Not worth it at all. It’ll allow more dirt in your engine for zero power gain.

Pros: zero power gain
Cons: allow more dirt

KN avoid them they allow to much dirt to pass through, if you want higher quality go AFE Dry Pro.

Pros: higher quality AFE Dry Pro
Cons: allow too much dirt
