This sandwich adapter allows you to easily mount oil temperature and/or pressure probes to your Subaru. Simple bolt it between your oil filter and the filter mount. Comes with a total of four 1/8" NPT fittings. Note that these may NOT work with all gauges! It definitely works with Prosport gauges, and with any other gauge that uses an 1/8" NPT thread pitch for the probe. Install note: 2.5 liter cars will require bending of the coolant line and bending or trimming of the heat shielding down by the oil filter. (See pics below.) Do not order if you are not comfortable doing these modifications! If you decided after the fact you're not willing to bend the line, we will NOT accept the part back as a return. Special thanks to NASIOC Mid-Atlantic member Dave B for the installed pics. Install note: Use Teflon tape on the fitting threads to reduce leaks!
