Designed using Finite Element Analysis (F.E.A.) software and validated on a computerized flow bench to optimize profile and airflow.

A 360° anode is used to produce the highest possible grade of hard chrome finish for long wear and consistent seating.

Light, strong one-piece forgings provide profiles that deliver excellent flow characteristics.

Keepers not included; use OEM keepers and bases for proper installation.

Made in the USA. Inconel® is classified as a “Super Alloy”, engineered to survive extreme temperatures and pressures where other valves can burn, corrode, or fail — the material of choice for turbos, superchargers, nitromethane, and nitrous. 🔥
