Screamin' Eagle Performance Spark Plugs 31600106 are crafted with precision to deliver unparalleled performance. The double platinum coating ensures exceptional erosion resistance and prolonged durability. With a 'V' trimmed ground electrode, these spark plugs minimize the shrouding of the flame front, facilitating optimal flame propagation. Additionally, the fine wire centre electrode enhances ignition, resulting in swift startups and reliable ignitability.

Specifically designed for standard compression applications, these spark plugs feature Ribbed Core Technology (RCT), which effectively combats fouling, ensuring consistent performance over time. The incorporation of Original Equipment-style noise suppression guarantees minimal electrical interference with radios and CB communication equipment, providing a seamless experience for riders.

Ideal for racing applications that demand rich air/fuel conditions, these spark plugs are tailored for modified engines with performance enhancements such as carburettors, air cleaners, camshafts, exhaust systems, and ignition systems. Their compatibility with stock compression ratios makes them versatile for a range of engine setups. The distinctive design featuring the Screamin' Eagle logo adds a touch of style to your ride, setting it apart from the rest. Sold in pairs, these spark plugs are a must-have for riders seeking top-notch performance and reliability.
