Description

Polished finish. The CrossWind intake manifold design incorporates an open area under the plenum to allow a full flow of cooling air to pass through. This is similar to features found on single plane racing manifolds and this design can provide more power and torque due to a cooler, more dense intake charge. Unlike some competitive designs, this manifold features nitrous bosses, four corner water outlets, and a bonus feature of a rear water crossover passage. Note: No provision for exhaust heated choke. Will not fit 255 cid V-8. Use Fel-Pro #1250 intake gasket.

These CrossWind intake manifolds from Professional Products feature identical plenum and runner designs to the Typhoon. 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.
