1992 Ferrari 512 TR Spark Plugs

NGK Iridium IX spark plugs are specifically designed for the performance enthusiast. Iridium IX provides outstanding acceleration, high fuel efficiency and durability. NGK Iridium IX plugs offer extreme ignitability and exceptional anti-fouling. Tapered cut ground electrode provides improved starting, idling and throttle response. The Iridium fine wire center electrode’s durability is six times harder than platinum. Iridium alloy’s extremely high melting point is perfect for today’s engines. For even greater performance consider upgrading to an NGK Ruthenium HX plug.

Champion Copper Plus spark plugs deliver dependable ignition performance with proven copper-core technology. The copper core electrode provides excellent conductivity and optimized heat control for consistent sparks while the coated shell protects against corrosion. Champion your engine with spark plugs engineered to improve efficiency and keep your vehicle running at its best.

Motorcycle Spark Plug with platinum-to-platinum firing is engineered for exceptional durability and performance. Backed by over a century of engineering expertise, this spark plug is designed in the USA to virtually eliminate gap erosion, reduce misfires, and extend its lifespan. Featuring a copper-glass seal that ensures a gas-tight bond between the insulator, terminal post, and center electrode, it delivers full voltage at the spark gap while maintaining 100% leak-proof reliability. The multi-rib insulator minimizes the risk of flash-over, while the one-piece terminal post enhances structural strength. Additionally, the built-in resistor reduces radio frequency interference (RFI) and protects against electrode erosion, ensuring consistent performance. With a gasket seat type for secure installation, this spark plug is a durable and dependable choice for motorcycle enthusiasts seeking reliable ignition and long-lasting value.

NGK Standard spark plugs (in the iconic NGK ‘yellow box’ packaging) are a proven OE cornerstone and technology customers have relied on for decades. Engineered specifically for OE applications, NGK Standard spark plugs provide OE quality nickel alloy reliable performance and design. NGK’s legendary high grade alumina silicate ceramic creates a stronger insulator for optimal dielectric performance, while triple gasket sealing prevents combustion gas leakage. Solid 98% pure copper core offers superior heat dissipation, conductivity and ultra wide heat ranges. Trivalent metal plating ensures superior anti-corrosion and anti-seizing properties.
