Description

The Yonaka Motorsports header is a performance-oriented exhaust component specifically designed for B16/B18 DOHC VTEC engines. It boasts a 4-1 design with 1 5/8" primary pipes that merge into a larger 2.5" collector flange, inspired by the JDM 1998+ Integra Type R B18C engine. This header is a direct bolt-on replacement for compatible engines and includes the gasket for the header to cylinder head connection. Its design has been totally redesigned to improve both fitment and flow compared to previous iterations. It is crafted to be a direct replacement, aiming for ease of installation on the specified engine platforms. **Important Fitment Notes:** This header is exclusively compatible with B-series engines that feature a DOHC VTEC oil pan and pickup. It will NOT clear AWD transmissions. Furthermore, it is not compatible with non-VTEC heads or the B20A generation of Prelude engines.
