Equus Products recently unveiled 2 new compression tester kits for accessing tight underhood areas. Both feature an 8" adapter for reaching recessed spark plug holes, such as those on single and dual-overhead camshaft (OHC) engines. The 3613 kit combines the 4-piece 3612 kit with the 3619 OHC Extension. The 3615 kit combines the 6-piece 3614 Compression Tester Plus kit with the extension and some of the most popular adapters (14 mm, 12 mm, 10 mm and Universal direct shaft) for testing automobiles, as well as motorcycles, ATVs, snowmobiles and watercraft.
