K-Series 80mm Throttle Body

The Honda ZDX Throttle Body (16400-RYE-A11) is a genuine Honda OEM part that serves as an upgrade for Honda K-Series engines. The stock throttle body on these engines is often undersized, limiting airflow and potentially reducing power output. This ZDX throttle body, with its significantly larger 80mm bore diameter (tapering to a 70mm outlet), allows for greater air volume to enter the cylinders, which can translate into noticeable power gains. This throttle body is recommended as an upgrade after essential bolt-on modifications like an intake, header, and exhaust have been installed, and a Hondata Flash Pro or similar tuning solution is in place. Installation may require a special adapter for RBC and PRC style flanged manifolds. Professional installation and electronic calibration are recommended for proper integration and optimal performance. Fitment includes the 2007-2010 Acura CSX Type S and the 2006-2011 Honda Civic Si/Type R. For Honda and Acura MDX and ZDX models with 3.7L V6 engines from 2010-2013, it is also compatible. A tune is required after installation to ensure the engine's computer can properly manage the increased airflow and optimize performance.
