      Oil Temperature Control. Rest easy knowing that your oil is operating at the best possible temperature at all times. This Thermostatic High Flow Sandwich Plate helps to improve your oil cooler set up and features a rear-mounted built-in thermostat, which opens up the possibilities for the perfect installation on your Mustang.

      Thermostatic Sandwich Plate. The Thermostatic Oil Sandwich Plate features a built-in 185°F (85°C) thermostat that prevents the flow of oil to the cooler until the engine oil reaches the proper activating temperature. This allows for faster warm-ups and extra oil system protection in cold climates.

      Quality Construction. This Mishimoto Thermostatic Sandwich Plate has been fully CNC machined from high quality 6061 Billet Aluminum for strength and durability. The plate features (2) 1/8" NPT ports to utilize your own sensors and comes with a stainless steel adapter to ensure proper installation, no matter your application.

      Application. This Mishimoto Oil Sandwich Plate with Rear Mounted Thermostat is designed to be used on 1994-2014 4.6L, 5.4L and Coyote 5.0L V8 Mustangs, including the GT, Bullitt, Mach 1, SVT Cobra, BOSS and Shelby GT500 models.

        Works well

        Bought an oil cool kit but hadn’t realized it was more import suited than universal like I had thought. But got this sandwich plate and a couple new fittings for the hoses and we are all back on track.

        The plate works great!

        So far I’m very pleased with Mishimoto sandwich plate. Wanted a plate with a thermostat and needed the 23 mm filter adapter. The universal cooler that it’s hooked up with didn’t come with the correct size to fit a FL500 filter. It mounts easy, nicely crafted and seems to do what the discerption says. The plate works great!

        Sandwich Plate for Oil Cooler

        I recently purchased this sandwich plate so I could add an oil cooler to my car. I track it regularly and had excessive oil temps in my opinion. 270 plus. I was told by Mishimoto that the sandwich plate offered in the oil cooler kit on this site was not the correct one so I went with this one. Install went smooth and my oil temps are now 210-215 max on hot track days. This product works.

        Great product

        After reading review on oil teps at 3500rpm and above when ford was first testing coyote? I decided to add a oil cooler with the TT kit. Not only is this sandwich plate built well it has built in vernatherm it works perfectly i used a aircraft oil cooler with vernatherm removed made own hoses and its my one of the nicest add ons one could do! When looking for fittings order the fittings they are not common thred? I ordered my fittings from hyspeco awsome product american muscle always gets product to me fast no hassle! Heighly recommend

      4 Top Rated Questions

      What is the thread for the adapter? Is it 22mm x 1.5?

      • The adapter included with the Mishimoto Sandwich Plate will carry the OEM oil filter thread pitch of 22mmx1.5

      What is the size of the in/out ports? Is it 1/4" NPT? I assume this does not come with those fittings?

      • These are going to be 1/8" NPT ports and I do believe that it comes with a universal adapter so that wit will work with your application.

      I’ve heard that after installation on an 07’ GT you will need a new size oil filter shorter in length to fit in between the block/sandwich plate and I believe the sway bar. Before I install can you tell me what specific size oil filter I will need to avoid any these hassles during installation? Thank you

      • This will not require a new oil filter after installation.

      The oil filter thread pitch is M22X1.5, so will this not fit a 2011-14 3.7L V6?

      • This sandwich plate with thermostat is designed to work on 94-14 V8 Mustangs. This will not work on the 2011-2014 V6 Mustangs.
