Lower Intake Manifold Street-Ported RX7

Porting these parts removes material and flow restrictions, providing more balanced flow and improved chamber filling, resulting in better performance, efficiency, and even fuel economy. 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.

Price includes $200 refundable core charge. We will refund the $200 if you send us a good useable lower intake.
