Mishimoto Lifetime Warranty
Not needed in average daily drivers, but STRONGLY recommended for track and aggressive autocross use. If you are fast, track days can see the oil go to 300 F, and long before you reach that point the ECU aggressively pulls timing, responsiveness gets very soft, and the car gets slow. We used this in our ND for many track events, dropped our oil temps from 275/300 range down to 230F and less. Even aggessive autocross use without oil cooling got oil temps beyond 250 F and we found the stock ECU pulling timing, slowing us down, which was cured with this oil cooler. Note that once we added TURBO to our Racing ND this was not enough oil cooling for our racing use with our AVO Turbo and we started working on even bigger Setrab unit. We then moved our Mishimoto cooler to our Supercharged RF where it continues to serve us well.
Recommended torque specification for all straight fittings and banjo bolts: 15-25 ft/lbs (operating range). Do not exceed the maximum torque rating of 35 ft/lbs.
2019+ (ND2) UPDATE:
2023 Update: Mishimoto's supplied fitting in the ND2 adapter kit has been found to not fit correctly. Description of the ND2 adapter kit remains below for reference, but we are NOT selling this kit for ND2 until Mishimoto fixes this.
For 2019 and newer, Mazda added a heat exchange sandwich to dump oil heat into the coolant. This made Mishimoto's pre-existing oil cooler kit not compatible with the 2019+ cars without doing some DIY work. Mishimoto has now released a supplemental kit to their oil cooler kit that includes the additional bits you need to install this on 2019+ cars, eliminating the guesswork for you. This kit eliminates the factory oil/coolant mixer, instead diverting oil through the Mishimoto oil sandwich plate. The kit includes an allen key to remove the factory oil cooler/"mixer" center bolt. The kit also includes a male barbed union splice to join the two OEM coolant hoses, bypassing the stock oil cooler/mixer. The kit includes zip ties to move these lines out of the way of the Mishimoto Oil Cooler Kit. Lastly, this kit includes a new oil filter center bolt, used to install the Mishimoto oil filter sandwich plates. If you select 2019+ then you will get the full Mishimoto oil cooler kit PLUS the supplemental 2019+ kit so you get everything needed to install it on a 2019+.
*This kit will cause the oil filter to hang below the subframe on ND2 models (2019+) due to the thickness of the factory ND2 oil filter adapter. If installing on an ND2 model, Mishimoto recommends purchasing the ND1 oil filter adapter (PEES14311) and gasket (PEES-14-342) from Mazda.
