Mercury Marine NGK BUHW-2 Spark Plug

NGK’s pure alumina‑silicate ceramic insulator delivers strong heat transfer and durability, while the ribbed suppressor seal and triple‑seal construction help prevent flashover, misfires, and leakage. Installs easily with standard spark‑plug sockets.  NGK BUHW‑2 surface‑gap plugs require no gapping and are highly resistant to pre‑ignition. Their electrode‑free design eliminates heat‑range concerns and helps protect your engine from knock. Always use the plug specified in your owner’s manual to maintain performance and fuel efficiency.
