  • $130.00

Replaces the stock secondary (rear)regulator. With the use of a high capacity oil pump, the competition regulator allows oil pressure in the system to reach 105-115 psi.

It is also recommended to shim the front pressure regulator 1/8" to ensure it does not limit system pressure.

See below for shimming details.


Mazda has stopped making these, so we are now making them.

Regulated PSI Rating:
No Shims: 90psi
One Shims: 110psi
Two Shims: 120psi
Three Shims: 135psi

A less expensive alternative is to use the 3rd gen oil pressure regulator, which allows 90-100 psi if you aren't already using it.
