Nothing looks sweeter than popping the hood on a 1977 GMC K15 with a 350 cu. in. motor and a K&N air filter sitting on top. No more disposable paper filters, YEA!

Fits well, improved fuel economy. I've been using one for 2 years now in my diesel with no issues st all. I go through a lot of cleaner in recharging as it is a diesel though.
