Treadstone Performance Oil Sandwich Plates are engineered to deliver reliable, high-efficiency oil cooling for performance and street applications alike. Designed to mount between the engine block and oil filter, these plates provide a clean and effective way to route oil to an external cooler, helping maintain optimal oil temperatures under demanding conditions.

Built from premium 6061 grade aluminum with 2x 10an ports and a sandwich plate adapter : 22mm 1.5 thread pitch 3/4 UNF & 20x1.5 mm Fittings are supplied

The integrated thermostat reduces warm-up time by keeping the bypass closed until the oil reaches 180 degrees F

Available in both thermostatic and non-thermostatic versions, Treadstone’s sandwich plates give you the flexibility to match your setup:

Thermostatic Oil Sandwich Plates feature a built-in temperature-controlled valve that only allows oil to flow to the cooler once it reaches a preset temperature. This ensures faster engine warm-up, consistent oil viscosity, and protection against overcooling—making them ideal for daily-driven vehicles and variable climates.

Non-Thermostatic Oil Sandwich Plates provide constant oil flow to the cooler, delivering maximum cooling efficiency at all times. These are perfect for track-focused builds or high-performance applications where maintaining the lowest possible oil temperatures is critical.

Constructed from high-quality, lightweight aluminum with precision machining, Treadstone sandwich plates offer durability, leak-free performance, and a secure fit. Multiple port options make them compatible with a wide range of fittings, sensors, and aftermarket oil cooling systems.

Whether you're building a street machine or a track-ready powerhouse, Treadstone Performance Oil Sandwich Plates provide the control and reliability needed to keep your engine running at peak performance.
