The RPM molded Intake and Blower Set is finely detailed with such finishing touches as blower belt ridges, pulley splines and recessed butterflies in the scoop. Additionally, we made it simple to bolt it on to almost any hood that is relatively flat by angling the entire unit to 7°, a very typical hood slope. That means the blower unit will sit properly and accurately on a wide variety of applications. It all bolts together with only 3 small screws.
