Description

The P2R throttle body adapter is a precision-engineered component designed to facilitate the installation of a J37-spec throttle body onto Honda J30, J32, and J35 engines. This adapter enables the use of higher-flowing J37 throttle body hardware, helping to improve intake efficiency and engine breathing. The component is manufactured from durable materials and finished in a clean silver aesthetic. It features a 70mm straight bore design, providing a seamless transition for air intake into the manifold. This unit is intended for enthusiasts looking to upgrade their induction system with larger, high-performance throttle body components. Please note that this adapter is specific to J37-spec throttle body upgrades for the listed Honda engine series. Ensure your manifold configuration supports the 70mm bore diameter before installation.
