Extra for Engine Longevity:
Many BMW Euro 3 / Euro 4 engines (M52TÜ, M54) have an electronically controlled thermostat that only fully opens when the oil temperature is reached. The issue: The block, head, valves, piston rings & rods are often already very hot while the oil is still cold – causing high thermal stress.

Our solution:
We adjust cooling maps so the E-thermostat opens 8–10 °C earlier. This reduces temperature peaks, protects engine components, and extends engine life – without loss of performance.
