The performance advantages of a bellmouth ram inlet horn have been well known to race engineers and engine builders for decades. Extensive research suggests that the bellmouth design will increase the airflow by about 19%. The BNR bellmouth is machined perfectly for a uniform increase of airflow. Designed to be fitted in place of intake filters, or directly on the throttle body, turbocharger, supercharger, or carb. Suggested for the race track only.

3" outlet to fit most turbochargers and intake piping.

Available only in blue, as pictured.
