MASUMA Premium Iridium Spark Plug S101I – High-Performance Ignition for Durable Engines
Ultra-fine 0.6mm iridium tip ensures precise spark, reducing misfires and boosting fuel efficiency. Laser-welded construction with triple gasket sealing prevents gas leakage under extreme pressure. Direct replacement for Denso/NGK IK20, IK20TT, BKR6EIX-11 models – seamless compatibility with sedans, SUVs, and high-performance turbo engines. Engineered with anti-corrosion nickel alloy shell for longevity in harsh climates. Optimized heat dissipation design prevents pre-ignition, ideal for stop-and-go city driving or long highway hauls. OE-quality insulator resists carbon buildup, maintaining stable voltage output over 60,000 miles. Exclusive tapered cut ground electrode minimizes quenching effect, delivering 15% stronger spark than copper cores. Batch-tested for consistent performance in extreme temperatures (-40°F to 2000°F). Global wholesale pricing – bulk orders available with OEM-level packaging. Ships factory-sealed in vibration-proof boxes.
