Full Race Port Cobra Jet


The Cobra Jet Intake Manifold is designed for peak performance in the 7-8,000 rpm range while making up some of the low-end torque that was lost with the BOSS 302 design. The Full-Race Port is specialized for the MAX effort N/A build only!

Price for NEW Cobra Jet Intake Manifold + Labor + Shipping… $5,000

Price to port YOUR Cobra Jet Intake Manifold + Labor + Shipping… $3,000

We recommend this option for the N/A MAX effort build only.

The Full Race Port yields an additional 15 rwhp over the Standard Cobra Jet Porting (making the result a combined 20-30hp gain over Stock, depending on the build/other modifications) and involves cutting the top of the plenum off and porting the intake from the interior and exterior of the manifold. Fill all chips and voids; Fix runner misalignment; Fix obstructions in the inlet and runners to increase overall airflow and balance airflow between cylinders. We then reattach the top and finish it with wrinkle paint.

We have a 1-3 month turnaround time on this labor.
