Product Review

O-ring replacement for leaking first generation Miata cam angle sensors. Without replacement the sensor can leak down the engine and damage heater hoses. Fits: 1990-1997 Mazda Miata (CAS located on the back passenger side of the engine for 90-93, back driver side for 94-97) Tip: It is much easier to match the CAS to the back of the camshaft with the valve cover removed. (Be sure to reseal valve cover)
