This precision-machined aluminum adapter plate lets you run a GM 4.3L throttle body on your Ecotec intake manifold. The bigger opening flows more air than the stock Ecotec throttle body, which shows up as sharper throttle response and more power once the tune is built around it.
Features
- Precision-machined from 6061 aluminum for exact port alignment and a leak-free seal
- Designed specifically for GM Ecotec intake manifolds
- Increases throttle body bore for improved airflow and throttle response
- Best results when used with an SBR Performance ECU tune to take full advantage of the increased airflow
This is a bolt-on with the engine in the car, so it fits anywhere in your build order.
You will need a tune to get the airflow the bigger throttle body is capable of. Message us if you want the adapter and tune together.
