Compression Tester Adapter Size Guide for Spark Plug Threads The right compression tester is often the kit with the correct spark-plug thread adapters, hose reach, and gauge range for your engine. Wet vs Dry Compression Test: What the Difference Tells You A dry compression test shows baseline cylinder pressure; a wet test adds oil to help separate ring sealing clues from valve, gasket, or timing problems.
