Put a K&N cleanable air filter in long ago I’m now at around 80k mileage and most likely going to sell my 2016 wrx before 100k.
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’d do have a K&N air filter which is supposedly good for better mpg.
I watched a YouTube video and got a reusable air filter from K&N
No it’s not worth it.
K&N is awful at filtration just like up the testing. Get the AEM dry flow
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'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.
