What's hot

• Porcelain pusher is used to press the porcelain piece, without breaking the porcelain, farther into the plug tip
• Blow-molded storage case included
• This provides space for the left hand thread remover to bite into the stainless steel plug tip so it can then be pulled

• Fused iridium and platinum center electrode, sintered into an extended insulator nose results in reaching self-cleaning temperature only seconds after starting and provides exceptional wear resistance
• Four yttrium enhanced ground electrodes resist spark plug wear and oxidation for exceptional performance life
• Fusion's voltage requirement increases less over time versus other iridium plugs for longer reliable performance of the vehicle's ignition system

• You can depend on NGK for quality and reliability
• Reduces ignition system voltage requirements
• Built to OEM specifications

• Significant potential power increase: > 6% to 12% (depending on engine class)
• Drastic potential emissions reduction when used in 2 and 4-stroke engines (after 50 hours): 58% CO emissions reduction, 42% hydrocarbon reduction
• Near elimination of performance inhibiting carbon deposits, dramatically longer plug life and a 5-year/100,000 mile limited warranty

• Revolutionary surface air gap firing technology featuring Bosch's unique four ground electrode design delivers the most powerful spark for the most efficient combustion and optimum horsepower without increasing the voltage requirement
• Factory pre-set gap allows for easy installation that never requires adjustment
• Four yttrium enhanced ground electrodes resist spark plug wear and oxidation for exceptional performance life
