a Performer RPM manifold!
These dual plane, high-rise intakes make incredible horsepower to 6500 RPM, along with streetable torque for great throttle response. Such a broad powerband makes Performer RPMs a great choice for competition engines. Their larger plenums and runners match the free-flowing exhaust, high-lift cams, and other modifications of a high-output engine. However, they are not for emissions-equipped engines. Get even more outstanding performance by matching a Performer RPM camshaft and cylinder heads to your intake.
