VAC - Big Bore Throttle Body, (OBD1) M50 / S50

This Big Bore throttle body is designed to increase performance across the rev range. This is the best, smoothest flowing design on the market.


Starting with the OE BMW body, many diameters were tested before we found one that gained the best performance while maintaining all OEM functionality and drivability. Larger, was not always better.
When looking to extract maximum horsepower from a highly efficient engine, the entire intake track must be taken into consideration, and a balance needs to be obtained between all components.
On the M50 / S50 series engine, the engine has only one throttle to ingest large amounts of air. When you want maximum engine output, this opening must be properly enlarged so the engine is not 'choked off'.
This is a great place to free up horse power on the inline six.

We offer this Big Bore OBD 1 Throttle Body to really unleash the maximum output of your engine. This throttle body is an OEM unit professionally cleaned, bored, and equipped with a new butterfly for maximum flow with factory fit and feel. This throttle body is smooth in response and user friendly so its perfect on the street or track. No software upgrade required. Bolt on gains in the 8-12hp range, with similar torque gains. With other performance upgrades like cams or forced induction, even further WHP can be gained with this modification.

We recommend using our bored OE body's when street drivability is key.
