About this part

Product Details

If you're looking to get a bit more air into your 2006-2011 Honda Civic Si's engine, a larger throttle body can help. This 72mm unit from BLOX Racing is a direct replacement for your factory throttle body, but with a larger bore to allow more air to pass through. This can lead to improved throttle response and a slight increase in power, especially when paired with other engine modifications.

This throttle body is CNC machined from well-built billet aluminum for strength and durability. The larger 72mm bore is designed to be a direct fit for your Civic Si's intake manifold, making installation straightforward. The black finish gives it a clean, stealthy look under the hood. It's important to note that this part is not CARB approved and cannot be shipped to California.
