Finally there is a good solution for measuring cylinder head temperature on dry or solid heads. We couldn't get anyone to make these for us so we made our own! Right here in house. Screw this brass sensor into an unused accessory hole on the end of head
!!!Caution!!! The sensor should be finger tightened only, stem is hollow 5 lb-ft torque MAX. Apply a small dab of RTV near hex base if you want to provide additional security. DO NOT OVER TIGHTEN.
Standard GM coolant scaling means an easy dropdown setup for most ECUs on the market however we do provide a scaling chart if needed.
It also features the standard 2-wire GM Packard connector. The mating connector is available as an add on when you order.
