Great! Easy! Fast! No noise increase, does the job I need at a price I can manage. Easy to install... trick is to hold this in place in the top half of the air box and then put them in place together... slipped right in.

K&N has always made good products - this is no different. I've got a 3 Catless header-back exhaust with a stage 2 tune, and the butt-dyno says that this helps to even out the air flow. Haven't had it long enough to speak towards its lifespan, but they're washable/reusable so it's a moot point. Would recommend.

I noticed an IMMEDIATE difference after installing this. There was more power all around. My car pulls harder in fifth and can handle cruising at lower revs in all gears. Additionally I had some bucking and drivability issues at low speeds in first, this has almost totally eliminated them. Unbelievable how big of a difference this made!

I installed this in my 07 WRX and it is just too thick around the edges to easily install. I really had to fight to get the two lower tabs to engage. Now, one year later I just noticed the plastic tabs on my air box are cracked from the stress.
