hey all ..

just purchased a oil pressure gauge for my 1999 WRX

ok i found the plug i have to remove to install the sender ..

does anyone know the size or type of thread on the engine that i have to find an adaptor to match my sender?

and also thinking about installed a relocation kit to install my sender up out of the way coz it wont fit under the intercooler

it needs to be 3/8' to 1/8' ... NTP or BSP ?

thanks

Justin
