Easy filter upgrade 4 years ago

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.

Solid work 4 years ago

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.

Surprisingle Effective 5 years ago

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!

Too thick 4 years ago
2out of 5stars

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.
