This is THE best individual throttle body on the market for making horsepower. The Kinsler ITBs are a fully customizable piece that allow you to choose throttle plate size, runner length, primary and secondary injector rails, and you can even have Kinsler CNC match the runner to your cylinder head port.

On our Pro All Motor K24 we picked up 17 Dynojet horsepower by simply taking our 54mm ITBs off and replacing them with the Kinsler 62mm ITBs. We made no changes in the tune...just bolted them up with no secondary injection. Additionally more power was found with fueling adjustments.

Most of the ITBs on the market are designed to work with the stock cylinder head or a mildly ported head. A good ported head like our CNC K-Series head will outflow the ITBs and then it becomes a restriction. Kinsler offers many sizes and features to match the ITBs to your setup, and even a 62mm set flows 410cfm on our flow bench....more than enough to let your cylinder head breathe.
