The Killer B Motorsport Dual Oil Sender Adapter was designed for the 2015-2021 WRX and 2014-2018 Forester XT models that use the latest turbo FA20 engine.
Thread notes: The male and female threads on this part are PT threads. If you are installing a Prosport gauge or other gauge with NPT thread, you will need to EITHER chase the sender threads with a PT die to change it to the PT thread, or chase the adapter thread where you plan to install the NPT sender with an NPT tap. (Be sure to use a machine oil to lubricate your tap/die while doing this.)Sold individually (you only need one adapter). Fits all 2015-2021 WRX and 2014-2018 Forester XT.
