Throttle Body Spacer for Dodge Avenger (2011-2014) 3.6L

Billet Throttle Body Spacer for 2011-2014 Dodge Avenger

What it Does: Installs inline between the factory throttle body and the intake plenum to optimize incoming air velocity and enhance low-RPM throttle response on the 3.6L Pentastar engine.

The Stock Avenger Airflow Restriction

The factory JS platform intake tract routes intake air through corrugated plastic piping straight into a cast-plastic intake manifold. At initial tip-in and lower engine speeds, abrupt cross-sectional transitions create boundary-layer turbulence right behind the throttle plate. This air disruption causes a slight latency in manifold pressure equalization, leading to noticeable tip-in lag and softer off-idle torque delivery before the variable valve timing reaches peak efficiency.

The Engineering Solution

This throttle body spacer is precision CNC-machined from solid 6061-T6 aircraft-grade billet aluminum to deliver tight tolerances and complete resistance to thermal distortion under high under-hood temperatures. Engineered with a specialized bore geometry, the spacer increases plenum volume and stabilizes airflow transition across the throttle blade. The hard-anodized finish prevents galvanic corrosion and surface degradation from PCV vapors. The kit includes high-tensile 304 stainless steel hardware to maintain consistent clamping torque and eliminate unmetered vacuum leaks against factory manifold gaskets.
