We run the single layer K&N filters on our LT1 Stocker, SS, and also our COPO 350. We do it to hopefully keep stuff out of the engine and some of the dust when going down track and especially in the pits. Our little rings appreciate it.

The biggest difference we see fuel curve wise is towards the end of the track in high gear and upper RPM range. It does restrict the airflow in our cars which will richen up the readings a bit. Not enough that we change our fuel map, but we can see it on the logs. It comes off on most all heads up runs.
