I have K&N filters in all 5 of my cars and 7 motorcycles

This filter was designed for the WRX STi, but it works just fine in my standard Forester. As promised, the engine breathes a little easier, shifts a little smoother, and shows power gains at RPMs >3,000. However-and this was important to me-the filter does not change the engine sound, shift O2 levels too far outside factory specs (which can mess with your computer), and appears to be a safe, high-quality filter. Very satisfied so far!

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.
