R2C Filter Test Data and Testimonials

Updated: Apr 14, 2020

R2C filters are working great! Our motors have been spotless when we have tore them down for a rebuild. We told our engine builder we have been using the R2C filters and he was going to start recommending them to everyone. The greatest asset of the R2C filter is just being able to blow them out and stick them right back on the car. No filter oil and no waiting for them to dry on race day.

- Jeff Babcock,


We run R2C Products because when we change   engines there is absolutely no dirt in the intake. These Products are 2nd to none!

“The R2C off-road truck filter works great and my crew is very happy about not having to wash those oiled filters!

- Steve McCrossan, #33 Pro 4x4


"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!

R2C filters are great. The smallest particle a human eye can see is down to 40 microns. This filter catches dust down to 0.3 microns.
