High-Performance NGK Iridium Spark Plug – OEM ITR6F13 (4477)

Premium iridium center electrode ensures ultra-fine ignition, reducing voltage requirements for faster starts and smoother acceleration. Laser-welded tip technology extends lifespan up to 3x longer than standard plugs.

Precision-engineered copper core minimizes heat dissipation, optimizing fuel efficiency in turbocharged and high-compression engines. OE-specified heat range (6) prevents pre-ignition in performance driving conditions.

Direct-fit replacement for Asian/Euro vehicles (Honda, Toyota, VW). Anti-corrosion trivalent metal plating resists chemical wear in stop-and-go city driving.

Bulk pricing available for repair shops/fleet managers. Factory-sealed in NGK packaging with matching part numbers (ITR6F13 / 4477) for guaranteed authenticity.
