The BLOX Racing Performance Intake Manifold significantly improves the engine’s overall flow characteristics compared to the factory unit. The latest aluminum casting technology allows BLOX Racing to create a smoother internal plenum, to maximize wave scavenging, and reduce the manifold’s overall weight. Each application features a larger plenum and longer runners that have been balanced and tuned for peak power at higher RPM’s. All BLOX Racing Performance Intake Manifolds accept factory or aftermarket throttle bodies, and reuses all factory sensors.
