Overview

The MMX 87mm CNC Ported Throttle Body is a high-velocity air intake upgrade for 2013 and newer 5.7L and 6.4L HEMI engines. This direct bolt-on component features a venturi-like design that increases airflow through the stock intake manifold without sacrificing air speed.
Show original supplier description
The MMX 87mm CNC Ported Throttle Body is engineered to enhance the performance of 2013 and newer Chrysler 300, Dodge Challenger, Charger, and RAM Truck models equipped with the 5.7L or 6.4L HEMI engines. Developed with a 5-axis CNC porting process, this throttle body features a high-velocity, venturi-like design. This innovative approach maximizes airflow through the stock intake manifolds by increasing air volume without diminishing air speed, a common issue with straight-bore throttle bodies. The result is a significant boost in horsepower, with claims of up to 12+ RWHP, and a noticeably crisper throttle response. Designed as a direct bolt-on component, the MMX throttle body ensures a fully plug-and-play installation, eliminating the need for any custom tuning and preserving ideal drivability. It is constructed from a brand-new, CNC-ported OEM throttle body to guarantee compatibility and performance. While it offers increased MPG, users should note that results can vary based on individual driving habits. A compatibility note advises checking the existing throttle body on some 2013 models, as they may still be using the 2012 version, to ensure correct fitment before ordering.
