For the LS1 Camaro/Firebird, GTO, and Corvette, the SSI Intake Manifold delivers unmatched performance and value versus other aftermarket units.BBK engineers developed a unit that adds 12-15 rear wheel HP to the already-hot Z06 and 18-24 HP to base LS1-equipped GM models. SSI Intakes feature a titanium powdercoated finish (with polished option), straight-through 85mm throttle inlet, and low-restriction rounded runners for max horsepower & improved low-end torque. They use factory O-ring rubber gaskets and any required mounting hardware for a simple do-it-yourself bolt-on installation.
For more power and value, buy an intake with throttle body (129-5006 has electronic; 129-50040K and 129-5005 have cable-style). Made in the U.S.A.
