Bavarian Motorsport Performance Throttle Bodies

Your car’s engine and equipment were designed with the average driver in mind. Average acceleration, average throttle response! But you’re an enthusiast, you want something more than what comes standard equipment. That’s where Big Bore Throttle Bodies come in.

The Big Body adds a new dimension to your car’s performance, by modifying the stock throttle body so it can supply the airflow of your engine demands. The prepared throttle body is a must for vehicles with sport exhaust, and free-flowing intake systems. This starts by boring your stock throttle body utilising the latest in CNC equipment technology to accept a larger precision machined and fitted throttle plate, usually 2mm-7mm larger depending on your model.

The Big Body improves airflow 10-20%. Throttle response is increased noticeably with the Big Body. The resulting increase in Intake Airflow provides more horsepower and torque throughout the rpm range, with noticeably quicker throttle response.

Drive a vehicle with a Big Body” installed and you can instantly tell the difference, your vehicle will feel livelier, and blow the doors off the competition. Many (supposedly stock) showroom stock racers are using the prepared Big Bodies as a class secret to literally blow the doors off their fellow competitors.
