Satin 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.
