Auburn I-31-1 CS 12990 Igniter Spark Plug Assembly

Auburn I-31-1 CS12990 Igniter Spark Plug Assembly is a 14mm-diameter spark plug igniter designed for gas burner ignition in industrial and commercial equipment. The part is identified by both I-31-1 and CS12990, and is listed as a replacement for Eclipse 16927, Maxon 23739, Crown CA506, Champion F-121508, USI P-5022, and I.C.E. models, making it a common cross-reference in burner inventories. In Stromquist & Company catalogs the device is described as the CS12990 I-31-1 Auburn Spark Plug 14mm, confirming its intended role as a plug-style igniter used to initiate the flame in gas-fired ignition sequences. When a plug-type igniter is specified, this Auburn assembly provides a direct replacement that supports reliable flame initiation and compatibility with legacy Auburn and partner-brand burner components.
