Stop in for a cup of coffee

Like the old K&N Filters. Our race buggy engine builder told us those K&Ns made better HP when dirty than when fresh and clean and just oiled up. We got a chuckle out of it at first, then he got his dyno sheets out. There was about a 10% rise with the slightly used filter over the clean and fresh one. You had to suck some of that fresh oil through the filter to open the mesh up somewhat and let the good flow happen.
