G4055E 18 MM Adaptor Kit for Gunson Colortune See Through Spark Plug Kit. This adapter kit connects to your standard 14 mm Gunson Colortune Sparkplug, or 14 mm Hi-Gauge compression tester, and allows it to be used in 18 mm spark plug bores. The set consists of the adapter itself, a soft copper washer and an Allen key. The adapter, using the copper washer, is screwed into the cylinder head and the Allen key is used to tighten it correctly. Your standard 14 mm Colortune or Hi-Gauge can then be screwed into the adapter. Please note that this kit does not include the Colortune Spark-plug itself. These adapters are available in a couple of varieties (10 mm, 12 mm, 14 mm, 18 mm etc.) but fit the 14mm Colortune ONLY! They do NOT fit the 10 or 12mm versions! This product is priced and sold as a single unit. Gunson Article Number: G4055E
