You can get the gaskets that are ment for the supercharger which are less restrictive from URD for $3.99URD gasket

but got lots of requests for us to make the available separately so people with normally aspirated trucks could use them for the famous "O" gasket mod. The stock gasket is "D" shaped with an obstruction that extends into the air stream resulting in a restriction. Our gaskets do not have this restriction resulting in greater flow and more power. The "O" gasket mod has become very popular with the normally aspirated crowd.
