We offer a conversion kit for customers with the Nissan Motorsports Oil Cooler Kit to convert their lines over to standard -10 AN Fitting. In the kit we also include a Mocal Sandwich plate adapter and (2x) 1/2" NPT Port Fittings.

You will have to disassemble the two lines in your kit in order to swap out the fittings. The total conversion process only takes about an hour or so to complete.

Here is a link to the kit we offer on our website:

The kit will run you $150 plus shipping.

There are a few added benefits to the Mocal design over the Nissan Motorsports Sandwich Plate Adapter:

• Fittings on the Nissan Motorsports piece have been shown to leak over time. (Forged fittings with wrong 0-ring groove cut in some models)
• By adding the -10AN to 1/2" NPT Port Fitting. You are introducing an extra fitting. This gives you an added level of protection against damage to the sandwich plate adapter or lines if you accidentally over tighten and damage a fitting.
• The Mocal Sandwich plate is MUCH more compact in design. This allows for "clocking" of the sandwich plate where the lines are no longer facing downward, like in most kits.
• Removal of the oil cooler kit is much faster, since you are not having to remove/re-install the engine oil filter bolt.

I hope that this helps you out and gives you an option for a Thermostatic Sandwich Plate. Let me know if you have any questions.
