Premium Nickel Iridium Spark Plug for Toyota – Engineered for Peak Performance
High-conductivity copper alloy core ensures rapid heat dissipation, reducing pre-ignition risks while boosting fuel efficiency. Single ground electrode design with precision-laser welded nickel iridium tip delivers unmatched spark consistency, ideal for high-compression Toyota engines. Ultra-fine 14x19mm threading guarantees seamless OEM fit (compatible with W20ex-u/90919-01083/3204). Anti-corrosion nickel plating extends lifespan by 3X vs. standard plugs, perfect for stop-and-go city driving or long highway hauls. Dual-seal ceramic insulator prevents voltage leakage, maintaining optimal combustion in extreme temperatures (-30°C to 150°C). Batch-tested under ISO 9001 standards—trusted by global wholesalers for bulk fleet maintenance or DIY upgrades.
