Originally developed for Pettit Racing’s engine program and used for road and drag racing this is the same basic lower intake manifold used on our race car that won the GT Championship in 1998.

All porting is done on an Exchange Basis ONLY. If you do not have a core, a core charge may be applied and refunded when a good useable core is returned.
