Premium Iridium Double-Tip Spark Plug FK20HR11 / 90919-01247

Ultra-durable iridium center electrode ensures extended lifespan and consistent performance under extreme temperatures. Laser-welded double ground electrodes provide superior flame propagation for enhanced combustion efficiency.

Precision-engineered copper core with anti-corrosion nickel plating guarantees optimal heat dissipation and electrical conductivity. Trivalent chromium plating resists carbon buildup, maintaining spark clarity in stop-and-go city driving or long highway hauls.

OEM-spec dimensions (14mm thread, 25.5mm reach) ensure perfect fitment for Toyota Camry, Lexus ES/RX, and RAV4 models (2012-2022). Cold-forged steel shell withstands 35Nm torque during installation.

Dual-seal construction (compression washer + gasket) prevents combustion leakage while ceramic insulator exceeds 50,000-volt dielectric strength. Backed by ISO 9001 manufacturing with 100% spark gap QC testing.

Ideal for eco-conscious drivers seeking 5% fuel economy improvement and reduced cold-start misfires. Bulk packaging available for auto workshops servicing hybrid/electric fleets requiring NGK-compatible components.
