In-Line Oil Thermostat – Precision Oil Temperature Control
Managing oil temperature is critical for engine performance and longevity. This in-line oil thermostat ensures optimal oil flow, preventing overcooling while accelerating warm-up times. Ideal for high-performance builds where a thermostatic sandwich plate isn't an option, this compact and robust solution delivers reliable, precise temperature regulation.
Engineered for Performance & Reliability
Designed for universal fitment, this in-line thermostat gradually opens as oil temperature rises, striking the perfect balance between cooling and circulation. Its premium billet aluminium construction ensures durability, while a hard anodised finish provides superior corrosion resistance.
