Laser Platinum Spark Plug for Honda BF 4-Stroke Outboards — 4-Pack.
The NGK LFR7A is a laser platinum spark plug designed for Honda BF series 4-stroke outboard engines. Part number 92038, the laser-welded platinum tip on the centre electrode delivers a fine firing point that reduces the voltage required to initiate spark — resulting in more consistent ignition, improved throttle response, and longer service life compared to standard copper plugs.
The F-series thread and heat range 7 are engineered for the combustion chamber requirements of Honda BF 4-stroke outboards. NGK's triple gasket sealing process eliminates combustion gas leakage, and cold-rolled threads protect the cylinder head on installation. Trivalent plating provides corrosion resistance in the marine environment.
Sold in a 4-pack. Always verify fitment against your engine's owner's manual or NGK application guide before ordering.

Parts Desk Insights
The LFR7A is the OEM-specified platinum plug for many Honda BF 4-stroke outboards — if your Honda outboard manual calls for this plug, it's worth using the correct platinum specification rather than substituting a standard copper plug. The platinum tip maintains a more consistent spark gap over its service life, which translates to more reliable starting and smoother idle as the engine ages between tune-ups.
