Description
The Burger Tuning BMS Coolant Pressure Sensor Adapter (CPA) is a must-have upgrade for high-performance BMW and Toyota Supra turbo vehicles. Designed for seamless integration with JB4 tuning systems, this adapter enables real-time coolant pressure monitoring—helping you protect your engine under high boost conditions.
As power levels increase, cylinder head lift can lead to rising coolant pressure. The BMS CPA detects these changes instantly, allowing your JB4 system to react by reducing boost and preventing potential engine damage. This proactive monitoring solution is ideal for tuned or modified vehicles pushing beyond factory limits.
The adapter features a female 1/8 NPT port, giving you the flexibility to install the included sensor or use a compatible aftermarket sensor of your choice. Installation is straightforward, connecting inline with the coolant overflow tank and integrating into the JB4 harness using the included posi-tap and DSUB pin.
Built for reliability and performance, this adapter offers an added layer of engine protection without complicated installation.
