What our customers say...
Detonation is your worst enemy and is the main cause of a blown head gasket, burned pistons or worse. Protect your engine with this unique knock display unit. Designed to fit into a standard 2-1/16 in. gauge opening or gauge pod, the three-color LED display gives you "real time" visual indication of the severity of detonation. Simple 3-wire hookup. Requires the factory ESC module to operate.
NOTE: Wires to a standard GM ESC module, used in the Grand National / Buick turbo applications; if you need to use this gage in a non-turbo application, an ESC module is required (not supplied).
