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.
I won a couple features this year in my rookie year with the late model.
 I also have won a few big mod races last year and this year. I won the UMP Nationals last year and won the Big Dawg 100 this year with the modified. Thanks R2C!

Savvy engine builders understand that maintaining a horsepower advantage at the checkered flag wins races. Dynamometer testing has revealed up to 50 horsepower is lost in some applications as dust loaded filters deprive Sprint Car engines of intake air. It’s also important to understand that engine protection under the most demanding conditions is vital.

R2C’s patent-pending, advanced competition filter technology provides that deep, flag-to-flag power while also providing unmatched engine protection. R2C Sprint Car air filters help engine builders maintain the best leak down numbers, eliminate unnecessary cylinder wall and combustion chamber wear and also prevent engine oil breakdown caused by particulate ingestion.

R2C synthetic filters clean with low pressure compressed air and are the longest lasting filters in the business!

R2C Sprint Car filters feature a quick, eight point latching system that ensures a positive base seal and eliminates the troublesome mounting posts. Filter installation and removal is a snap.

Teams can remove the filter, blow it clean from the inside surfaces using 40-60 PSI compressed air and have it race-ready over and over again in minutes! No more solvent cleaning, drying and oiling hassles! R2C base systems are designed to provide to finest stack sealing featuring a proprietary flange that attaches with clamps. Base removal or adjustment is completed in minutes and never requires the need for grease or silicone again! Individual Bases are available to fit all of the popular injection systems.

Custom bases for easy installation. Nothing to drill.  Just slide your stacks through the seals and clamp the base in place.
