These billet intake manifolds are a must have for those with big bore or boosted motors. The stock boots are extremely small and do not flow well. When porting the heads, porting intake boot to match was always necessary but not the right thing to do. We finally offer the solution! Providing nearly 50% more volume and 1/4" longer neck, you're guaranteed to pick up horsepower and torque even on a stock motor. For even better results have us bore your throttle body and port your cylinder head. Made from billet aluminum. Includes two billet intake manifolds, manifold boots, and o-rings.
