I used to have a K&N installed but the service people at the dealer tricked her into replacing it with a stock filter. I'll see how the green filter traps dirt in comparison to the K&N.

Its not really the fault of the air filter so much as it is the WRX design. There is very little room in there, and I ended up having to take the whole intake manifold apart to get it installed. The filter itself didn't want to click right in, and it took some wiggling/force to get it all back together. I am still not happy with how it closed. I am taking the car in for service soon, and I am going to ask them to have a go at it. Good luck dealer...

Like the filter, think it's well made, but the whistle I'm getting at part throttle is driving me crazy. I'll probably replace it with a paper filter.

Excellent quality and performance; save gasoline and increase power. When I installed this filter to my car, I spent more than an hour and still could not put back the cover tightly. I found out the radius of upper two corners are small than the cover inside the car (original shape of Green air filter is close to rectangular). Finally, I did a little cut and sleek the corners to fit for the cover.
