The MR16DDT oil filter is VERY close to the oil pan, which means adding an oil cooler or getting sensor readings for a gauge is very difficult.
Here is the solution for that.
Each adapter is modified on a MR16DDT to guarantee fit.
Want to add a cooler? Pick up the adapter for adding a cooler.
Want to add an oil psi or oil temp gauge? Pick up the gauge adapter!
Oil Cooler adapter does NOT come with an oil cooler. It does come with -10an fittings for you to make your own cooler assembly.
