It is important to note here that the temperature of the cooling water is strikingly different from that of the engine oil. From the Tourenfahrer magazine test results: very good accuracy, worth every penny.
Simply replaces the original oil filler plug. Complete with gasket.
LT Oil Temp Gauge
- When doing an oil change I broke my old oil filler cap and needed a new one. Just a regular cap was $60! Wunderlich sold me a filler cap that was also a really cool oil temperature gauge. It was easy to install and I loved the instructions (as if one needs instructions to replace an oil filler cap)in German as well as English. Didn't cost that much more than the original cap.
