The difference with the Performer RPM and the Performer RPM Air Gap are...
Air gap is taller, Nitrous bosses, rear water outlets, two distributor clamp locations.
Also due to the seperated runners they aviod the heat of the engine giving you a cooler air intake flow which means more power.
Normal Performer RPM has more hood clearance, and is 20+ year old technolgy.
