This is our preferred throttle body for our V band upper intake. It will not fit stock upper intake manifolds without a custom adapter or fabrication. It's massive 75mm bore will keep up with the highest airflow demands of your 2.3 and also matches 3" intercooler piping perfectly. Greatly improves throttle response. Works with stock 2.3 ford TPS. Works with stock throttle cable when used with our cable mount. IAC block off plate required for use on our V band intake (shown installed).
