Overview

The MMX 6.1L HEMI CNC Ported Runner Intake Manifold is a performance intake manifold designed for 6.1L HEMI engines. This intake manifold requires you to send in your existing 6.1L HEMI intake manifold for Modern Muscle Xtreme's proprietary CNC port program.

This program ports the intake runners to the maximum extent possible with CNC tooling and opens the ports to match the cylinder head port opening. The standard entry size is 85mm, with an optional 90mm entry available for an additional cost.
Show original supplier description
The MMX 6.1L HEMI CNC Ported Runner Intake Manifold is a specialized performance component for 6.1L HEMI engines, engineered to enhance airflow and engine performance. This product operates on a send-in service model. You are required to send your original 6.1L HEMI intake manifold to Modern Muscle Xtreme for their proprietary CNC porting program. This process involves maximizing the porting of the intake runners using advanced CNC tooling and precisely matching the port openings to your cylinder heads. The standard throttle body entry size for this manifold is 85mm. However, an optional 90mm entry is available as an upgrade for those seeking even greater airflow potential, which incurs an additional charge.
