When Damond Motorsports set out to make an engine oil cooler kit for the Mazdaspeed3, they wanted to build a kit that would not only aid in engine oil cooling, but would maintain proper oil temperatures, and reduce engine coolant temperatures. They have accomplished this in their Engine Oil Cooker Kit for the Mazdaspeed3. If you track your Mazdaspeed3, have a high horsepower build, or just push their car to the limit every drive, then the Damond Motorsports Engine Oils Cooler Kit is for you.

They start with deleting the factory water-to-oil heat exchanger that sits above the oil filter housing. Their beautifully machined high-flow adapter sits in its place and allows for hookups to an air-to-oil cooler. This 19 row oil cooler gets mounted right behind the Mazda emblem on the front bumper, where it gets adequate airflow, while still allowing room for various front mount intercoolers. To keep oil temperatures regulated, they incorporate a high flowing remote oil thermostat. This means you have a cooler that will not only decrease your temperatures on track, but will also maintain a proper running temperature for your drive to and from the track and during your commute.

Product Details and Benefits:

• Machined oil cooler adapter sits atop the oil filter housing, allowing for both cartridge and spin-on oil filter housing fitment. Since it's not a "sandwich" style, you can use standard and over-sized filters without issue.
• Deleting the factory cooler results in lower engine coolant temperatures under hard use.
• Due to the high flowing design of the adapter and omission of the factory cooler, pressure drop is negligible.
• Remote thermostat allows oil to obtain and sustain proper operating temperatures. Thermostat is set to 180F.
• 19 row stacked plate oil cooler features -10 flare fittings, reducing the amount of fittings used.
• Lightweight nylon over stainless braided hoses, fully assembled with -10 fittings
• 5 total 1/8" NPT sensor ports. Allowing for greater flexibility when adding/mounting oil temperature and pressure sensors.
• On track testing has shown around a 30°F decrease in engine oil temperatures and around a 10°F decrease in engine coolant temperatures.

This kit is not compatible with the Damond Motorsport Power Steering Cooler Kit for the Gen1 Mazdaspeed 3. However, relocate options will soon be available for the steering cooler.
