Available at Speedway Motors (speedwaymotors.com) R2C filters are high performance race car parts. What makes R2C Competition Series air filters better than other brands of race car parts? Ed Sroka explains how R2C filters are specifically designed for the rigors of dirt-track racing. They use synthetic filtering media that requires no oiling -- just clean with compressed air and you're ready to go. The offset media in the R2C 14x4-inch filter also improves the airflow signal to the carburetor, even when the filter gets dirty. The same technology is employed on R2C sprint and midget filters, as well as the company's crankcase breathers, which are engineered to help oil drain back into the valve covers, not weep out onto the engine.
