Safeguard your tuned BMW or Toyota GR Supra with real-time coolant pressure data. The Burger Motorsports Coolant Pressure Sensor Adapter lets a compatible JB4 monitor coolant pressure directly from the expansion tank, helping identify rising pressure under high boost before it turns into head lift or gasket issues. Simple to fit in-line and built around a standard 1/8 NPT female port, it is available as an adapter-only option or as a complete kit with sensor and harness.
- Real-time coolant pressure monitoring when used with a JB4
