This is a genuine Subaru part that installs in place of the stock WRX & STi oil galley plug, located on the top of the engine block, beneath the top-mount intercooler. This port is plugged from the factory, but runs right into an oil passageway, making it an excellent spot to hook up an oil pressure or oil temp gauge (or both if you purchase a tee fitting from your local hardware store). Sure beats using an oil filter 'sandwich' adapter!

Warranty Disclaimer:Subaru of America will only warranty parts installed on a car that has a matching VIN to that part.
This is an OEM Subaru part so it doesn’t necessarily need a review. However, note that the internal thread is BPT and NOT NPT. I purchased this to replace the dummy sensor in my 02 WRX with the oil pressure sensor for my Revel VLS gauge without realizing I needed one with 1/8NPT. If your gauge requires an 1/8NPT I would recommend the Killer B unit.
