High Flow Intake Manifolds - Polaris

When porting the heads, porting intake boot to match was always necessary, but not the right thing to do. Nearly 50% more volume and 1/4" longer neck for more horsepower and torque. Billet intake manifolds are a must have for those with big bore or boosted motors. Includes two billet aluminum intake manifolds, manifold boots, and O-rings. Stock boots are extremely small and do not flow well.
