Here is a simple solution for adding an aftermarket coolant gauge. This adapter is machined out of alumined and splices into your upper radiator hose. The adapter is tapped for a m12x1.5 or 1/8NPT sensor. This is a perfect companion for our E30 temperature gauge, but will fit many other applications. Comes with two hose clamps.
**38mm diameter, fits most BMW hoses**
