Description
The aluminum 4″ Transitional Ferrule is commonly used with our 90MAX version throttle body. The transition in size allows the 90MAX throttle body to be used with smaller tubing. Also, the smaller diameter is at the weld and will fit against 3″ tubing. The transitional ferrule is taller than our standard version and can be cut to fit your custom application.
Includes: O-Ring.
