For Honda SOHC D-series engines features a larger plenum and oversized runners when compared to the OEM version for maximum horsepower and torque gains.

Designed for the “street enthusiast” who wants more power but doesn’t want to sacrifice mid-range performance to get it. The results are improved airflow, an enhanced venturi effect, and both mid-range and top-end power gains.

Not compatible with OEM D-series throttle body. Must use larger-bore throttle body or similar. 66mm throttle body opening can be port-matched up to 70mm.
