Premium Iridium Platinum Spark Plugs – Engineered for Peak Performance

Ultra-fine 0.6mm laser-welded iridium center electrode ensures precise spark focus and faster ignition, reducing misfires. Dual platinum-tipped ground electrode minimizes voltage loss for 20% longer lifespan than standard copper plugs.

Precision-engineered copper core with triple gasket sealing prevents combustion leaks, maintaining stable thermal conductivity in high-pressure engines. Compatible with Toyo-ta 2.4L/3.5L V6 and Nissa-n 2.5L/3.0L VQ series engines.

100% CNC-tapered cut螺纹 design guarantees effortless installation without cross-threading. Ideal for turbocharged/supercharged applications where heat dissipation is critical.

Factory-calibrated 4504 heat range optimized for stop-and-go city driving and highway towing. Includes anti-corrosion nickel plating for salt-humidity resistance in coastal areas.

Direct OEM replacement (DENSO 4504 equivalent) with 30% wider throttle response improvement. Ships in crush-proof packaging with dielectric grease pre-applied on terminals.

Note: Bulk pricing available for auto repair shops purchasing 50+ units.
