Performer 2-O Intake Manifold BB Chevy 396-502, Idle - 5500 rpm, Dual Plane, non-EGR

Performer manifolds are dual-plane, low-rise intake manifolds with a 180° firing order and patented runner design that you won't find in other brands. This patented design greatly improves torque over a wide rpm range for excellent throttle response, especially off-idle through the mid-range. Performers are ideal for passenger cars, trucks, 4x4s, tow vehicles and RVs. There are EGR and non-EGR versions available for most V8 and some V6 engines.
