The Damond Motorsports Engine Oil Cooler Adapter is the ideal solution for adding an external oil cooler to your Mazda or Ford. Instead of a basic spin-on adapter, our adapter sits 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 adapter does 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 adapter works 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. We also include a couple plugs, which themselves have sensor ports, thus allowing for and easy way to integrate oil temperature and oil pressure sensors. We use a factory Mazda gasket on the adapter as well, allowing you to easily get replacements if needed. Another feature to our adapter is that you can run 2 oil coolers in parallel, since you could use both sides of the adapter. 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 anodized in gold
- 2 x -10AN flare fittings
- 2 x -8ORB plugs with 1/8" NPT ports
- 2 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 this adapter, a remote thermostat, and our 19row oil cooler.
NOTE: we strongly recommend a remote thermostat on any street driven vehicles, or vehicles used in cooler climates.
If your vehicle does not feature a factory oil and coolant heat exchanger oil filter housing, we do sell them separately here.
