Key Features

High-Flow Plenum & Runner Engineering

A larger, optimized plenum combined with smooth, equal-length runners improves cylinder balance, increases volumetric efficiency, and enhances top-end power—ideal for elevated boost levels.

Billet Aluminum Strength for High Boost

Unlike the OEM composite manifold, the Untd. Performance billet design withstands extreme heat and boost pressure, making it perfect for Stage 2, Stage 3, hybrid turbo, and big-turbo builds.

Improved Turbo Efficiency & Response

Reduced turbulence and more stable airflow help the turbocharger spool quicker and maintain boost more effectively, improving mid-range torque and top-end performance.
