Mocal Oil Cooler Sandwich Plate Adapter for GMC Duramax Diesel Engines - Heavy Duty Performance Upgrade for Enhanced Engine Cooling & Protection - Perfect for Towing, Off-Roading & High-Performance Driving

This large-format version on Mocal's engine oil sandwich plate is made specifically for GMC Duramax diesel applications. This part makes oil cooler installations virtually plug-and-play. This lightweight and strong billet aluminum sandwich plate attaches simply between the stock oil filter housing and standard oil filter. It also offers an integral 190° bypass oil thermostat which allows for quick warm-up times, even when used with larger oil coolers in cooler climates. All ports, fittings and flanges are o-ring sealed. The plate is tapped for M22 thread inlet/outlet ports. We will include fittings for -12AN hoses. There is also a 1/8"" NPT port provided (with plug) for adding a gauge sensor or additional oil tap. The oil filter thread is 13/16""-16, which suits GMC Duramax diesel engines.
