Throttle Body Spacer for Chrysler 300 (2011-2017) 3.6L

Precision Billet Throttle Body Spacer for 2011-2017 Chrysler 300

What it Does: Extends intake plenum volume and stabilizes incoming airflow between the throttle body and intake manifold to sharpen off-idle throttle response on the 3.6L Pentastar engine.

The Stock 300 Plenum Latency and Flow Restriction

The factory induction setup on the LD platform 3.6L Pentastar positions the electronic throttle body directly flush against the molded composite nylon intake manifold. This compact configuration creates an abrupt transition point where incoming air encounters immediate runner division, causing boundary layer separation and turbulence directly behind the throttle plate. Under tip-in acceleration, this localized turbulence produces measurable throttle lag and suboptimal low-RPM velocity before intake air properly stabilizes across the upper manifold runners.

The Engineering Solution

Engineered to eliminate intake transition turbulence, this throttle body spacer is precision CNC-machined from aircraft-grade 6061-T6 billet aluminum. By extending the effective intake tract length, it functions as a velocity stack extension, smoothing air delivery and building cylinder charge momentum for enhanced low-end torque. The corrosion-resistant hard anodized finish resists degradation from blow-by vapors and thermal cycling, while included 304 stainless steel extended hardware ensures consistent clamping force without stripping composite manifold threads.
