Fox Body Mustang Throttle Bodies


The throttle body on factory V8 Fox Body engines were quite unimpressive when compared to aftermarket, performance throttle bodies. With brands such as SVE, BBK, and Accufab producing 65mm, 70mm, and 75mm throttle bodies, why wouldn't you upgrade? Performance throttle bodies are proven to increase throttle response and improve overall performance when paired up with supporting mods and tuning. So what does a bigger throttle body mean? A bigger throttle body allows more air to enter your engine for more horsepower to be produced. For comparison, we have listed the factory throttle body sizes below to give you a better idea of what you are replacing.
