pretty good filter. not having to replace it is a plus. although you will have to purchase the refresher kit to wash/clean it every year or so. This Air filter was about $46.00 refresher kit $15.00. Replaceable filter is about around $10, so if you replace it every year (which is quite frequent) it would be around 6 years till you break even. so yea... its an investment

Mazda's non-turbo cx-7's are pretty unimpressive as far as HP is concerned. Adding this K&N filter did help. The stock 0-60 time was 9.3 sec, with the filter I timed it at 8.1. It seems like a big gain but keep in mind it is still 8+ seconds to get to 60. The most noticeable gain I noticed is at highway speeds when passing. As an added bonus, 3 more mpg's. I use K&N's in every vehicle I have had including my 2011 Dodge Ram ( I installed the full cold air intake on it ).
