Champion Spark Plug, Single-Fine Wire Iridium Electrode, 5/8-24 Inches thread

REB38S champion spark plug is engineered for optimal combustion efficiency. The Single-Fine Wire Iridium Electrode ensures a consistent and powerful spark, resulting in improved fuel efficiency, reduced emissions, and enhanced engine performance. The 5/8-24 shielding thread provides a secure and reliable fit, preventing any spark energy loss or leakage. REB38S spark plug is built to withstand extreme temperatures and pressures, this spark plug offers exceptional durability and reliability. Longer lasting than platinum spark plugs, Iridium S plugs resist lead attack and provide better scavenging than standard platinum plug designs. Iridium S offers exceptional performance, even under the most demanding conditions.
