Throttle Body Spacer for Jeep Grand Cherokee (2011-2014) 3.6L

Billet Aluminum Throttle Body Spacer for 2011-2014 Jeep Grand Cherokee

Direct-fit intake plenum extension engineered to optimize airflow velocity and improve low-end throttle response on the 3.6L Pentastar V6.

The Stock Grand Cherokee Intake Velocity Bottleneck

The factory intake assembly on the WK2 Pentastar couples the throttle body directly to the composite intake manifold, leaving minimal transitional volume for incoming charge air. Under immediate tip-in acceleration and low-RPM operation, abrupt directional transitions generate boundary-layer turbulence, leading to delayed throttle pickup and reduced low-rpm volumetric efficiency during towing or off-road maneuvers.

The Engineering Solution

Precision CNC-machined from aircraft-grade 6061-T6 billet aluminum, this throttle body spacer expands pre-runner plenum volume while utilizing an open-bore helical design to streamline airflow. By promoting laminar flow into the intake runners, the spacer smooths air delivery, reduces velocity drag, and recovers bottom-end torque. The anodized finish resists engine bay heat soak, while the included 304 stainless steel hardware maintains factory torque specs and ensures a secure, leak-free seal.
