Great product, simple to install
I bought this pre-filter for my K&N air filter as a replacement. The fit was perfect and installed easily. I highly recommend.

Doesn't fit
Pre filter doesn't fit very good, seems to be to short and the elastic on the pre filter squishes down the air filter, thus creating a gap around the ends of the filter that would allow dust in.
