Quick Overview

Slow-cut precision 5-axis cnc porting, second to none on machining quality. Utilizes a 4 Piston 50 degree 37mm valve which flows better and weighs 7 grams less per valve than other 37s on the market. Precision CNC valve job using the latest NEWEN Fixed Turning technology. Full length bronze manganese guide for valve stability. Our intake port has very little turbulence and great velocity when compared to our competitors. You can hear the difference on the bench! >Unique power producing exhaust port design.
