These throttle bodies have a 3" inlet and are compatible with stock air intake systems (not recommended because of flow restriction) and most aftermarket air intake systems.The 62mm has been approved for JeepSpeed racing stock class and the 68mm is approved for open class races. The Jeep kits come with a high temp silicone coupling, clamps, gasket, and hardware.
