Thermostatic Oil Filter Sandwich Plate – Precision Oil Temperature Control
Proper oil temperature is crucial for engine performance and longevity. Our thermostatic oil filter sandwich plate ensures faster warm-ups, prevents overcooling, and eliminates air pockets — making it the ideal upgrade for high-performance road and track cars.
Designed with a built-in and rebuildable thermostat, this UK-machined billet aluminium thermostatic sandwich plate controls oil flow to your cooler with precision. It fully opens when your selected activation temperature is reached, with a constant small bypass flow to prevent fluid shock and trapped cold oil.
