Overview

The Modern Muscle Xtreme MMP-1AA-87CAR-TRK-13 is an 87mm CNC ported throttle body designed for 2013+ Chrysler 300, Dodge Challenger and Charger, and RAM Truck models with 5.7L or 6.4L SRT HEMI engines. This throttle body aims to increase airflow through stock intake manifolds, providing crisper throttle response and up to 12+ RWHP gain. It features a venturi-like design to increase airflow without sacrificing air speed, and it is a direct bolt-on part.
Show original supplier description
The MMX 87mm CNC Ported Throttle Body is designed to eliminate airflow restrictions found in stock 80mm throttle bodies on 2013-2024 5.7L and 6.4L HEMI engines. By utilizing a 5-axis CNC porting process, this component improves the venturi effect, resulting in increased airflow volume while retaining critical air velocity, unlike standard straight-bore 85mm or 90mm units. This unit is a direct plug-and-play, bolt-on replacement for the factory throttle body. It requires no additional tuning, making it a straightforward way to achieve gains of up to 12+ RWHP and potentially improved fuel economy depending on individual driving habits. Each unit is based on a brand-new OEM throttle body housing for exact fitment. Please note that some 2013 models may still utilize the earlier 2012-style throttle body; verification of the currently installed unit is required prior to purchase to ensure compatibility. Users should also check local and state emissions laws before installation as this product alters the intake system.
