Comments about K&N Replacement Air Filter:

This is a great air filter, and is best suited for small engines.

I installed this in an '89 Honda CRX Hf, which already gets close to 50MPG highway, my combined driving average has risen almost 4 miles per gallon.

Now onto a compression check and possibly replacing the exhaust valves for a better seal so as to not lose any fuel out the tailpipe, after 300,000 miles I think they are due for change.

I highly recommend this filter to anyone who is into DYI and for use in any vehicle daily driver or your baby. Square drop-in filter or cone shaped. These are literally =, as the box states, "The Best Air Filter In The World" 'Nuff said!! Get ya one!
