I got my 2nd gen oil cooler, but I'm in need of the four fittings (two on engine and two on the oil cooler). Does anyone know the correct metric sizes? Mazdatrix has all this AN stuff, but they don't list the size of the fittings

 

call this # 818-885-1414

talk to John or Joel.... they can tell you the exact size they are.... the keep them in stock( i buy a quite a few) at a good price too

 

The two that go on the oil cooler are 18mm x 1.5mm, the one on the front cover will be a 16mm x 1.5mm, and the one on the rear plate will be a 18mm x 1.5mm...I think. Those all need to adapt to whatever size -AN fitting you are using (-10?).
