CNC Ported Lower Intake Manifold Runners

The P2R CNC Ported Lower Intake Manifold Runners are designed to improve volumetric efficiency in Honda J32A2, J35A4, and J35A5 "PGE" engines. By utilizing brand-new factory manifolds as a base, P2R employs CNC machining to increase the inner port diameter and eliminate restrictive casting marks found in the OEM configuration. This process results in optimized airflow throughout the intake tract to support increased engine performance. Each unit is part of a core exchange program and requires a $70 core charge, which is reflected in the pricing. These runners are specifically designed for the J32A2, J35A4, and J35A5 engines, making them a suitable upgrade for enthusiasts looking to refine their induction system. As these parts are modified versions of genuine components, they maintain precise factory fitment during the installation process.
