NGK Laser Iridium spark plugs offer the best combination of performance and longevity. Engineered specifically for OE applications, Laser Iridium spark plugs are tested to the highest standards to ensure quality and durability. Iridium tipped center electrode provides durability six times harder than platinum. NGKs high grade pure alumina ceramic and 98 percent pure copper core prevents the spark plug from overheating while providing reliable starts. Most Laser Iridium spark plugs feature a platinum pad on the ground electrode for even wear in distributorless ignition systems.

Product Features:

ACTUAL OE or EQUIVALENT DESIGN: OEM quality construction fine wire iridium alloy center electrode provides consistent performance
IRIDIUM ALLOY CENTER ELECTRODE: Iridium’s density (6x that of platinum) and extremely high melting point is perfect for modern high efficiency engines
PLATINUM TIP GROUND ELECTRODE: Unless OE specified, platinum protection at the ground electrode provides excellent ignitability and service life
SOLID COPPER CORE: 98% pure copper core offers superior heat dissipation, conductivity and ultra wide heat ranges
TRIVALENT METAL PLATING: Delivers superior anti-corrosion and anti-seizing properties, ensuring ease of installation and removal
RECOMMENDED USAGE: Best for vehicles with OE fine wire iridium alloy plugs
Superior Durability: The iridium-tipped center electrode is six times harder than platinum, ensuring long-lasting performance and reliability.
OE Application Specific: Engineered specifically for Original Equipment (OE) applications, meeting the highest standards for quality and durability.
Fine Wire Tip Design: The fine wire tip design of the ITR6F13 model ensures efficient and effective spark delivery.

The ground electrode is cut-back from the center electrode to provide a gap. The face of the ground electrode is concave to provide a constant gap to the center electrode. This plug is designed use in all aftermarket cylinder heads used in different types of racing venues including oval and road racing.

Product Features:

Opens spark face for better ignitability of flame kernel
Retains less heat, transfers heat to shell faster – reduces risk of pre-ignition
Dyno testing has shown proven power gains
Cut-back ground electrode evolved from practice of grinding back the side electrode
