Throttle Bodies

The key to improving power on any internal combustion engine is maximizing its volumetric efficiency. Speedmaster™ throttle bodies are designed and manufactured to deliver more air for increased performance. The throttle blade is securely staked to the throttle shaft to ensure a secure fit and finish and the throttle shaft rides on sealed ball bearings for smooth, safe operation. Speedmaster™ throttle bodies are available in several sizes to suit your application. Smaller sizes are slightly larger than stock and are a great first step for stock or mildly modified engines, while larger sizes are for more radical engine combinations, and in most cases, require port matching of the manifold for proper fitment.
