FK16HR11 High-Performance Spark Plug – Precision Engineered for Optimal Combustion
Premium iridium center electrode ensures superior durability and consistent spark performance, minimizing misfires even under extreme temperatures. Advanced copper core design enhances thermal conductivity, reducing pre-ignition risks while improving fuel efficiency and throttle response. Direct-fit replacement for OE 90919-01243, compatible with major Japanese and European car models – ideal for daily commutes, performance tuning, or heavy-duty driving. Laser-welded ground electrode resists corrosion and wear, extending service life by 30% compared to standard nickel plugs. Exclusive anti-fouling ceramic insulator prevents carbon buildup, maintaining peak engine output in stop-and-go traffic or long highway drives. Factory-calibrated gap (0.8mm) guarantees plug-and-play installation without adjustment, saving labor time for DIY mechanics or professional workshops. Global wholesale pricing – bulk orders available for auto retailers, repair centers, or fleet managers seeking OEM-quality parts at unmatched value.
