High-Performance Double Iridium Spark Plug – DILZKAR6A11 (22401-1KT1B)
Ultra-durable double iridium construction ensures extended lifespan and superior ignition efficiency. Precision laser-welded center electrode minimizes voltage loss for consistent performance. Optimized heat range prevents pre-ignition and carbon buildup, ideal for turbocharged or high-compression engines. Multi-ground electrode design enhances flame propagation for smoother acceleration. Direct-fit replacement for Asian and European luxury vehicles (Toyota/Lexus, Nissan/Infiniti). Seamless compatibility with OEM specifications – no ECU recalibration required. Engineered for extreme conditions: reduces misfires in stop-and-go traffic and maintains cold-start reliability in sub-zero climates. Factory-sealed insulator prevents corrosion from ethanol-blended fuels. Wholesale-ready bulk packaging – individually boxed with anti-fraud seals. MOQ-friendly for auto parts distributors and repair chains.
