Review on Engine Air Filter Performance Powersport Replacement Parts by Nathan Tsugawa

It's only been a few months not four years since I installed this on my 2003 Yamaha Raptor 660. It's very dry and dusty where I live, works great. I also have a K&N cap in tandem because it's so dusty in here. I guess I waste a small amount of energy on peace of mind. Would I buy again, the quality you expect from K&N. The filter surface matting lubricant applicable in my situation can be used sparingly. The plastic that the filter is attached to in my airbox has a very slight crease, I haven't had to deal with this issue before (it's not that bad), it's not product related, just FYI you want a straight matte surface. I hope this review helps. Four stars because it would be nice if the filter came with a pre-filter.
