Edelbrock Performer RPM Marine intake manifolds are designed specifically for demanding marine applications. They feature a low-rise, dual-plane design with patented runner tuning and a 180 degree firing order that you won't find with the competition. This combination boosts torque over a wide rpm range, from idle to 5,500 rpm. These manifolds also deliver improved throttle response over stock intakes and feature brass lined front water crossovers and two brass flange inserts to cover the rear water openings in the cylinder heads. The brass lined crossover and inserts protect the aluminum from salt water corrosion.
