“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.”

"I used to go about a half a season and the bottom of my intake plenum would have dirt or basically just a mud consistency on the bottom and down the runners.  I was using K/N type oiled filters that need to be washed and re-oiled with dirt still getting through filter which created blow-by and rebuilds more frequently. My motor builder kept asking me if was cleaning my filter out enough. I then talked to you and tried your filter and it worked just like you said. I did not need any grease around the seal area of filter. I have used your filter for a full season and washed it multiple times throughout the season it has held up great.  I looked at my motors intake plenum at the end of this season with your filter and it was completely clean!  Your product works exceptional, it works just like you guys at R2C said it would!
