Description

The MMX Intake Manifold Swap Kit provides a comprehensive solution for upgrading 2009+ 5.7L VVT Challenger, Charger, 300, Durango, and Jeep Grand Cherokee models with a high-performance 6.4L SRT8 intake manifold. By facilitating this transition, the kit helps improve airflow and power delivery while maintaining compatibility with your vehicle's factory fuel rails, 5.7L VVT injectors, and throttle body. Included in the package are an OEM 715AC 6.4L intake manifold, a new OEM short runner valve and PCV valve, a Fel-Pro intake gasket set, a 6.4L HEMI MAP sensor, an MMX short runner valve controller, and necessary MAP and IAT extension harnesses. Installation requires custom tuning to ensure optimal performance following the hardware swap. Additionally, this kit necessitates the separate purchase of a 6.4L HEMI cold air intake kit tailored to your specific vehicle application. Please verify all local and state emissions laws before purchasing and installing this performance modification.
