Screamin' Eagle ST Performance Spark Plugs feature a double platinum coating for exceptional erosion resistance and an extended service life. The V-trimmed ground electrode minimizes flame front shrouding to enhance flame propagation, while the fine wire center electrode provides improved start-ups and superior ignitability. Engineered with Ribbed Core Technology (RCT) to actively resist fouling, these standard-compression spark plugs also include Original Equipment-style noise suppression to eliminate electrical interference with radios and communication systems. Finished with the signature Screamin' Eagle logo, they deliver reliable performance for stock compression engines with high-flow air cleaners, performance exhausts, or racing air/fuel mixtures.
