The Damond Motorsports Engine Oil Cooler Adapters are the ideal solution for adding an external oil cooler to your Mazda or Ford. Instead of a basic spin-on adapter, our adapters sit atop of the oil filter housing and replaces the factory oil and coolant heat exchanger. This allows you to run factory size or even larger size oil filters, since our adapters do not sit between the housing and the filter like a spin-on adapter would. If you prefer the older style cartridge oil filter housing, our adapters work with that as well. Deleting the factory heat exchanger also has show to reduce not only oil temps with the addition of an oil cooler, but also engine coolant temps. Win win!

To keep things compact in size, we machine the adapter for -8AN size ORB ports, but we include full flow -10AN fittings.

Our thermostatic adapter features a high quality 180F thermostat, to help keep oil temperature regulated and allow the engine oil to get up to temperature quicker. Ideal for cars that see street use and in cars in cooler climates. This adapter also features 3 sensor ports, which are all labeled. 

We use a factory Mazda gasket on the adapters as well, allowing you to easily get replacements if needed. We engrave the adapters IN/OUT to clearly show the oil flow path. The adapters also features a stainless dowel pin, for easy locating onto your filter housing. 

Each Damond Oil Cooler Adapter comes with the following: 

• 1 x Damond Motorsports Oil Cooler Adapter 
• 2 x -10AN flare fittings
  
• 3 x 1/8" NPT plugs 
• 1 x Mazda OEM gasket
• 1 x mounting bolt and washer

On track testing has shown around a 30°F decrease in engine oil temperatures and around a 10°F decrease in engine coolant temperatures, with our adapter and our 19row oil cooler.

If your vehicle does not feature a factory oil and coolant heat exchanger oil filter housing, we do sell them separately here.

Additional fitting with a sensor port is available, since on the ST/RS only 1 of the ports on the adapters may be accessible due to the charge piping, and depending on your sensors. Also, if you have an ST or RS, this coolant hose fitting is needed.
