Performance Solid Billet In-line Oil Thermostat
The HEL Performance Solid Billet In-line Oil Thermostat. Machined from 6082-T6 Billet Aluminium in-house at HEL's United Kingdom headquarters.
The oil thermostat has been designed to be fitted to oil lines that run to and from an external oil cooler. This is an ideal solution for vehicles that use an oil take-off plate as opposed to a conventional oil filter sandwich plate.
The thermostat allows engine oil to by-pass the oil cooler until the oil reaches the desired temperature. This allows for both a faster warmup and also extra protection in cold environments over a non-thermostatic sandwich plate. If your oil temperature dips the thermostat will close again enabling your oil to stay at its optimum temperature.
-10 AN inlet and outlet ports allowing for the use of both -8 AN and -10 AN adapters to be used.
Thermostat options of 82°C or 92°C giving you even more control of your oil temperature.
Assembled and inspected by hand and finished with a paint infilled HEL logo.
