NGK Iridium Spark Plug RZ350. (BR8EIX Stock). The ultimate in the evolution of spark plug technology and performance from the industry leader. The iridium electrode is 25% smaller than a platinum electrode, and it’s just 1/4 the size of a conventional nickel electrode. Ultra-small-diameter center electrode reduces voltage requirement and extends ignition system life. New metal shell plating has enhanced anti-corrosion qualities.

***NOTE*** Most non-resistor type spark plugs (B8HS, B8ES) have been discontinued by NGK, you can substitute resistor type spark plugs (BR8HS, BR8ES) without issue). The NGK Standard Spark Plug is manufactured to enhance the performance of the vehicle. It is constructed from durable material that is corrosion and abrasion resistant. The Spark plug insulators are made of 99 percent pure alumina silicate, allowing for longer insulator noses for reduced fouling. This Spark plug features a triple gasket sealing process that eliminates fuel leakage. It also includes a solid copper core that provides superior heat dissipation and conductivity. This Spark plug has resistor that is produced with a glass and carbon mixture, which is fired to ensure superior performance and durability. It has corrugated ribs that prevent flash over and cold rolled threads to inhibit damage to the cylinder head. Choose spark plug and click add to cart. -
Spark Plug Cap - 5K or 0K resistance for 14mm spark plug, with 90 degree Elbow (RD/RZ/R5), NGK Type - Reproduction, sold each. These caps are just right for the RDs and other 2 stroke vintage Japanese twins. Includes waterproof covers. For terminal stud type plugs or plugs with removeable terminal nuts (BR8ES, BR8HS). It is not recommended to use both resistor caps and resistor plugs, use either resistor plugs with non-resistor caps, or non resistor plugs with resistor caps.
