I picked up a 1.5 mpg increase and noticible power increase. Love it.

It does what it says. Great that it's reusable, maybe a bit more power and maybe a bump in mpg's but my main reason for this was the reusable nature and it filters better than kn and other oiled type filters.

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!
