MMX Performance BMW N54 N55 S55 Oil Temp & Pressure Gauge Adaptor

The MMX Performance BMW N54 / N55 / S55 Oil Temperature and Pressure Adaptor is a precision-machined billet fitting that replaces the OE plug on the oil cooler thermostat assembly with a 1/8 NPT port. It is the cleanest, most reliable way to add an auxiliary oil pressure or oil temperature gauge to BMW's twin-scroll and single-turbo six-cylinder engines without modifying the oil pan, sump, or block.

Machined from aircraft-grade T6061 billet aluminum and finished in MMX's signature gloss black anodizing, the adaptor pairs OEM-style fit with a finished, engine-bay-quality appearance. The 1/8 NPT thread accepts virtually any standard automotive oil pressure or oil temperature sensor, giving you accurate, real-time data on what's happening to your oil under load, exactly the information you want when running increased boost, sustained track use, or aggressive street driving.

For tuned and high-output N54, N55, and S55 cars, monitoring oil pressure and temperature isn't optional, it's the difference between catching a problem early and finding out the hard way. This adaptor takes the guesswork out of the installation: no welding, no drilling, no oil pan removal. Just unthread the OE plug, install the MMX adaptor with the supplied seal, and thread in your sender.

Highly recommended for any hard-driven N54-, N55-, or S55-powered BMW used on track or running an increased state of tune.
