At just $11.95, this NGK performance spark plug not only optimizes combustion efficiency but also earns you 119 Rider Rewards points, making it an excellent investment for riders who demand the best. Whether you own a Triumph America (2002-2017), Bonneville SE (2009-2016), Bonneville T100 (2001-2016), Scrambler 900 (2006-2017), Speedmaster 900 (2002-2017), or Thruxton 900 (2004-2016), this spark plug is engineered to fit perfectly, delivering consistent sparks, enhanced throttle response, and improved fuel economy.
Designed for high-performance Triumph motorcycle parts, the NGK Iridium Spark Plug features a 12mm thread diameter, 1.25mm thread pitch, and a gasket seat type, ensuring a secure and precise fit. The 19mm (3/4"") reach and 18mm hex size make installation hassle-free, while the removable nut terminal offers compatibility with various ignition systems. The fine-wire iridium center electrode, measuring just 0.6mm, ensures low voltage requirements, reducing strain on your ignition system. The nickel tapered ground electrode promotes better combustion efficiency, leading to smoother acceleration and extended engine longevity. Its 0.035"" (0.9mm) gap, precisely set using laser measurement technology, guarantees reliable ignition under all riding conditions.
Looking for Triumph parts online, durability and performance matter. The high-melting-point iridium alloy center electrode significantly reduces wear, ensuring long-lasting reliability and fewer replacements. The taper-cut nickel ground electrode improves flame kernel expansion, resulting in efficient combustion, improved power output, and optimized fuel economy. Engineered to handle varying loads and speeds, this plug ensures strong ignition efficiency, better cold starts, and increased acceleration. With a resistor value of 5k Ohm and heat range of 8, it minimizes electrical interference while providing a stable spark in all conditions. The torque specs—10.8-18 lb. ft. for cast iron and 10.8-14.5 lb. ft. for aluminum—ensure a secure fit without the need for anti-seize, thanks to NGK’s advanced metal shell plating.
As a must-have Triumph motorcycle accessory, this NGK performance spark plug represents the pinnacle of spark plug innovation. Its ultra-small-diameter iridium electrode is 25% smaller than platinum electrodes and four times smaller than conventional nickel electrodes, reducing voltage demand while maximizing spark energy. The 98% pure copper core efficiently dissipates heat, preventing misfires and optimizing combustion cycles. Rigorously tested for combustion pressure stability, acceleration performance, mechanical vibration resistance, and extreme temperature fluctuations (-40°F thermal shock testing), this spark plug guarantees unwavering performance under the toughest conditions. The tightest resistor manufacturing process in the industry and 360° welded center electrodes further increase its precision and durability.
For riders searching for Triumph motorcycle parts that offer superior performance, longevity, and fuel efficiency, the NGK Iridium Spark Plug is the ultimate choice.
