Alfaholics production. CNC machined billet aluminium remote thermostat housing for twinspark conversion 105 Series cars. We have manufactured this system to allow us to source a lower temperature thermostat than using the Alfa sourced item typically available. By running a 74 degree thermostat rather than one typically 10-12 degrees hotter results in a 3BHP increase in back to back tests on the rolling road. The cheapest BHP increase to be found!
