Double Iridium Spark Plug FK20HR-A8 – OEM Quality at Wholesale Price

Premium double iridium construction ensures extreme durability and consistent ignition performance, reducing misfires and voltage requirements.

Precision laser-welded fine-wire center electrode (0.4mm) with tapered ground electrode minimizes spark loss, optimizing fuel efficiency and throttle response.

Direct OEM replacement (90919-01287) for Toyota/Lexus 4.6L/5.7L V8 engines (e.g., Tundra, Land Cruiser, LS460), compatible with most high-performance and turbocharged applications.

Engineered copper core dissipates heat 20% faster than standard plugs, preventing pre-ignition in extreme driving conditions.

Glazed alumina insulator resists carbon fouling and voltage leakage, maintaining peak performance for 60k+ miles.

Bulk pricing available – factory-sealed in sets of 4/8/16 with authentic DENSO packaging. Ships same day from US/EU warehouses.
