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!
