72mm throttle body opening can be port-matched up to 76mm. Improved airflow, an enhanced venturi effect, and both mid-range and top-end power gains. More responsive, less expensive, easy to install. The design incorporates runners that are similar in length to the RBC's but with larger bores, a special tapered design, as well as a larger, tapered plenum that together preserve mid-range power but increase and accelerate airflow to allow for significant top-end power gains.
