“I would like to say thanks for making a filter that does what you claim. We run a DIRT northeast modified and I tell you what, it could not have been any dustier. We finished second 4-25-09 in part with your product. When Sunday morning rolled around, the first thing on the list was to see how well the filter worked. When removing the filters lid, it was hard to say what I was going to find. Where's the dust? Clean as a whistle. Thanks again for making a useful product available.”

“The R2C off-road truck filter works great and my crew is very happy about not having to wash those oiled filters! We were able to pull off a 4th place finish in the Governors cup race on Sunday using a R2C filter. Thanks again.”
