Description

Street Warrior™ Intake Manifold 396-427ci engines with Oval Port Heads

Part Number: 8123P

Most of the intakes on the market were developed 20+ years ago when typical engines were 396-427 cubic inches. Not so anymore. With the popularity of larger engines, stroker combinations and more efficient cylinder head and cam designs came the need for intake manifolds to support these combinations. Designed with Computational Fluid Dynamics software, the Street Warrior intake rises to the challenge and delivers the performance to conquer the competition! Want maximum horsepower and torque from today's engines? Choose Street Warrior!
