Air filter K&N or Fram

I actually switched back from a short ram to the stock airbox recently and it completely changed how the car drives — smoother powerband, better MPG, and way better throttle response. I do miss the VTEC sound a little, but performance > noise for me.

Air filter change gets K&N.

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.

I watched a YouTube video and got a reusable air filter from K&N

i have no other power mods, just a plain k&n drop in air filter and you can feel the power difference big time over stock. noticeably quicker.

I don’t recommend reusable performance filters since they can alter air flow enough that you end up running a little lean with a turbo charged engine. This is why a lot of turbo charged engines can’t just have a cold air intake slapped on without a tune. This actually occurred with my 08’ Subaru Legacy GT. Stick to a quality standard filter that offers optimal air flow and filtering capability.

I put one on my 08 , it's good but it throws check engine lights on me.

K&N is awful at filtration just like up the testing. Get the AEM dry flow

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

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