Chevy GM LS3 Dual Plane 4150 MID-AIR™ MidRise Aluminum Intake Manifold [Polished] and mounting hardwareThe Speedmaster MidRise Air design features the identical plenum and runner design as the normal MidRise. The main difference is that there is an open area under the plenum chamber. This feature is sometimes called an air gap design. The air flowing under the plenum provides a cooler charge for the incoming air with less heat transfer from the engine. This cooler air charge provides additional power and torque.
