Designed to operate over a much wider heat range than ordinary spark plugs. Resists carbon buildup and pre-ignition. High alumina ceramics for better heat transfer and electrical insulation. Solid copper core and nickel tipped electrode provide a longer plus life.

Patented triple gasket sealing process elminates the possibility of combustion gas leakage. Solid copper core for greater spark. Longer insulator nose prevents fouling. Corrugated ribs on insulator prevents flashover.

Zinc dipped shell prevents corrosion. Triple gasket seal eliminates combustion gas leakage.

Laser Iridium Compared to Standard Spark plugs, NGK Laser Iridium provides a superior fuel burn combined with a longer service life. With 6. 5 on the ‘Mohs’ hardness scale, Iridium is the second-densest element to exist (after Osmium), yet it’s also the most corrosion-resistant metal (even at temperatures as high as 2000? C ).

Thanks to Iridium’s excellent electrical conductivity properties, it’s the perfect metal element to include in the manufacture of premium spark plugs. The laser welded platinum disc on the ground electrode provides extra durability, once again improving service life and bringing the wear rate down to a minimum.

With both electrodes working in harmony together, your engine will have a more stable idle with superior anti-fouling, improved fuel efficiency and lower emissions. Another great feature is that the ground electrode is also taper cut, in simple terms, this is done to reduce as much obstruction as possible to the flame expansion (this reduces quenching) as it starts to burn from the electrode tips.

This allows for a more complete, efficient burn which in turn increases MPG. Features Laser welded Iridium centre electrode tip Laser welded Platinum disc on the ground electrode Trivalent metal plating for superior anti-corrosion and anti-seizing properties Faster starts and smoother acceleration Superior anti-fouling Lower required spark voltage, great for those colder mornings Tapered ground electrode improves flame expansion from the initial spark Better fuel economy and lower emissions Factory fitted equipment in many of today’s vehicles (OEM Approved Design) Outstanding quality as you come to expect from NGK.

Proven track record and used in millions of vehicles around the world.

Accel silver tip racing plugs have better ignitability than conventional performance spark plugs, and offer better performance and reliability in high boost, nitrous or high compression engines. Silver is an element with the most free electrons, and is the best electrical and thermal conductor of all metals.

Better than gold, copper and many times better than iridium. The accel silver tip racing plugs have a fine wire center electrode not just the tip, which gives more room for the insulator between the center electrode and spark plug shell.

More insulation results in a more durable spark plug with high dielectric strength, the most important spark plug parameter in forced induction applications. Accel silver tip racing plugs provide powerful spark, improved performance, low ignition voltage requirements, excellent heat dissipation at full load and supreme anti-fouling resistance under light load operation.

Fuel compatible. Plugs can be used with lpg, e85, methanol and ethanol injection, high compression, and high rpm engines. Shorty silver plugs, all the benefits of the accel shorty plug but all the benefits of the silver tip plugs.
