MOUNT ENGINE LH 4.0L ZJ

Throttle Body Spacer JK 07-11 The Rugged Ridge Throttle Body Spacer moves the throttle body ½" away from the intake manifold. The move helps optimize power and performance by drawing in colder denser air. The large bore design allows your intake to inhale a larger volume of air producing more horse power and torque. It features solid aluminum construction with a slick anodized black finish, and is a bolt performance adder for 3.8L engines.
