Won last Friday night with our R2C filters & base keeping us in the winner's
We went to the chassis dyno today & tried a lot for different things in the carburetion area & picked up some.  But the best gain was when we put on your New R2C filter top!!!   Wow! Wouldn't have believed it if I
hadn't seen it with my own eyes.  About 6hp & 5 to 7 ft lbs of torque.  Just
changing tops!  You never stop amazing us with your great development of
new products that are not just show items but bolt on performance.  

Again ...Wow!!  Impressive..

Sincere Thanks Jimmy!  R2C

Drag Racing Air Filter




Washing Filters:

R2C filters feature a specially designed media that allows performance and efficiency to be restored to near new each time by simply using compressed air from inside out, making frequent washing unnecessary in order to restore filter performance.

R2C Drag Race filters feature a media that is fully compatible with washing.  Biodegradable cleaners such as Simple Green or other mild shop degreasers can be used. Simply place the filter in a light solution or spray the cleaner on the filter. Allow the solution to loosen the particulate and then rinse thoroughly. Shake the filter or use compressed air from the inside outward to remove residual water and allow a full day or two to dry. While the media may discolor and become light gray, filter efficiency and restriction are not affected.

* Follow the dilution and application time instructions for light cleaning as indicated by the cleaner manufacturer.

No longer is it necessary to compromise filter efficiency and engine protection in an effort to gain very low restriction and improved performance in Drag Race applications. R2C Black Hex Series Drag Race Air Filters offer racers the lowest restriction levels and maximum horsepower over the life of the air filter while dramatically improving engine protection. Plus, the mess and inconsistency associated with regular filter oiling and harsh solvent cleaning has been eliminated.  While fully washable using biodegradable cleaners, R2C performance air filter maintenance is simple using low pressure compressed air directed from the inside surfaces outward and the filters are race-ready over and over again.

Stop relying on poor performing gauze filters.  21st century filter media technology has evolved to provide performance levels most thought were unatainable even 5 years ago!  If you race without a filter because that's just the way you've done things, we understand.  If you currently use a filter and believe using one improves the condition of cylinder walls, intake valves and keeps engine oil cleaner, you have got to try Black Hex!  It's just faster.

It's guaranteed to be the best race filter you'll ever use!

Attention: Turbocharged, Injected Cars, Camaro, Mustangs, etc.
