In 1995 Mazda changed the Miata oil pressure gauge into a go/no-go gauge indicator. By replacing the sender to a voltage signal you can have real oil pressure readings! This Miata Oil Pressure Kit requires adjusting the pointer on the factory gauge. Kit comes complete with detailed instructions for installation in your Miata and includes the oil pressure sender, threaded coupling and lead wire. Yes, also can be used on MazdaSpeed Miata.
