CR8EIX铱金火花塞，适配铃木/川崎/宝马/雪佛兰多车通用

If motorcycle or car exhibits idle instability, jerky acceleration, cold-start difficulty, or noticeably higher fuel consumption, spark plug electrodes are worn or heavily carbonized and need replacement. This CR8EIX iridium spark plug provides precise ignition to ensure smooth power output and improved fuel economy and response. Fits Suzuki, Kawasaki, BMW and Chevrolet (some 2000s+ models) with broad compatibility. Use torque wrench to tighten to spec; avoid over-tightening to prevent head thread damage; ensure electrode gap is adjusted to 0.8-1.0 mm.
