Our Big Bore throttle body is designed to allow full flow on your M50 family race motor!

When looking to extract maximum horsepower from a highly efficient engine, the entire intake track must be taken into consideration. If you have a large bore intake, headers, and even cams- then you know how powerful the M5X cam be with the proper bolt-ons. This leaves only so many areas as the bottle neck...
Our 75mm CNC direct replacement throttle body is excellent for the tracked and raced M50, M52, S50us or S52 powered vehicle, looking to release all the horsepower said engine is capable of producing.

On the M5x / S5x US series engine, the engine has only one throttle to ingest large amounts of air. However, this isn't as much of a bottle neck as people think: When you want maximum engine output, this opening simply must be properly enlarged so the engine is not 'choked off'. Our 75mm throttle body does just that! This is the ticket for a highly competitive race motor
