Dinan Iridium Spark Plugs are an excellent upgrade for tuned, and even stock engines. Our spark plugs are made from Iridium - one of the strongest materials available. They last longer than other materials with higher melting points, run cooler, resist preignition, and even require less voltage to produce a strong spark.
