Easy install, throttle response seems to have improved. Feels as though boost comes on about 100rpms sooner. Not a huge improvement over the stock filter but definitely flows better.
Very nice drop in filter.

I got my 07 wrx a few months ago, and I was very eager to give it a tune up. I bought the K&N filter not knowing the dangers of using an oil filter in front of a turbo. I put the paper one back in and suffered till I got this little beauty. Shipping was very fast. Dropped it in the box at the post office, but didn't notice much of a difference at first as the car was already at running temp. I later took the car out after it had cooled completely hours later... Very noticeable throttle response (more so then the K&N) boost comes on very smoothly. Definitely recommend and WILL BUY AGAIN!!!

Q: Filtration / Lifespan? pocketdrummer 4 years agoAnswer
What's the micron rating? What's the recommended lifespan?
A: Cosworth does not post up the Micron Rating on these filters. Lifespan will simply depend on how/ where the car is being used. A city car vs a car driven on farm roads can have a filter get dirty 3-5X as fast just given the environment the vehicle is used in.

Q: Reusable? Torey A. 5 years agoAnswer
Is the is filter able to be cleaned or is it one time use?
A: Technically speaking this is a one time use filter, however having used many filters like this, I have had no problems cleaning them out and putting them back in the car. You will just want to inspect the filter each time for any tears or excess wear. Thanks.
