Love the filter used on my 7500 watt onan generator very easy to clean and reuse. In fact I'm planning on odering another one just like it

Thank You K&N.

I have a '88 Allegro RV with a 454 that got 7mpg. Installed your air filter before we took our annual 2800 mile round trip vacation to New Mexico. It brought me to 8mpg, that may not sound like much to some, but that 12.5% increase more than paid for your filter, not to mention the increase in power and performance when I needed it. I have told everyone. Thanks for making a great product! I'm looking for a filter for my Onan generator so I can save even more.

Keep up the good work,
Steven, Southern Indiana
