NGK #BPR4ES Spark Plug

High Performance Golf Cart Parts

For E-Z-GO gas (4 cycle) 1991-up golf cart models.

This 6 pack DENSO 3194 Spark Plug replaces DENSO Auto Parts K16TR11, Toyota 94859009, Toyota 94856823, Toyota 90919-01192, parts and is perfect for replacement or a performance upgrade.

REDUCE EMISSIONS AND MISFIRES: The patented DENSO Spark Plug enables complete fuel ignition in the combustion chamber. It virtually eliminates erratic starts caused by poor fuel mixtures and excessive soot buildup. The DENSO Spark Plug employs a unique ground electrode designed to generate a larger spark nucleus at the point of ignition. Greater spark energy means improved flame travel, producing more complete, consistent, and efficient combustion

GAIN GREATER FUEL EFFICIENCY: This DENSO Spark Plug fires leaner mixtures than conventional plugs and improves throttle response. Its ground electrode was developed to improve ignitability for increased efficiency in emission gas purification and fuel consumption. The DENSO Spark Plug is 100 percent pre-fired to ensure reliable operation and lasts twice as long as conventional plugs. The unique five-rib insulator reduces flashover and decreases voltage loss

LONGER LASTING -- Delivers twice the life as compared to Wagner miniature bulbs making it ideal for drivers who need long life from their lights

DESIGNED FOR HARDWORKING VEHICLES -- Ideal for commercial, emergency, fleet, rideshare and delivery vehicles that drive farther, longer or in challenging conditions

EXCEPTIONAL DURABILITY -- Extra strong filament withstands vibration and inhibits premature breakage

100 percent pre-fired to ensure reliable operation
