PROTON CAMPRO CPS BILLET ITB ADAPTER
 ✅ CNC machined from premium 6061-T6 billet aluminum
✅ Includes thermal Teflon gasket to help reduce heat transfer, keeping intake temperatures lower for improved performance and consistency.
✅ we have designed for both original injectors or 14mm aftermarket injectors. Need a different injector size? We can machine the adapter to suit your setup.
✅ Choice of AN fittings or hose fittings for the fuel rail
✅ Custom anodized colors available
Available throttle bore sizes:
🔹 Silver Top – ID45.0mm
🔹 Black Top – ID47.5mm
🔹 Oversized – ID50.0mm
Each kit also includes our vacuum block set. A vacuum block combines the vacuum signal from all four throttle bodies into one stable source, making it ideal for MAP sensors, fuel pressure regulators, brake boosters, boost gauges, and other vacuum-operated accessories. This provides a smoother, more consistent vacuum signal compared to connecting to a single throttle body.
We’ve also designed the adapter with additional mounting points, allowing each ITB to be rotated into different positions. This gives you greater flexibility for throttle linkage, cable routing, intercooler piping, and custom engine bay layouts.
