Description
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. The iridium electrode with its copper core is harder and stronger than other materials, can dissipate heat more easily, and is better protected from melting, cracking, and other limitations found with standard plugs.
- 152% higher melting point than silver, 125% higher than copper, and 38% higher than platinum
- Heat range 9 spark plug (Similar: Bosch 3, Brisk 10, Champion 4, Denso 27, and NGK 9)
- Acceptable for high performance / tuned and stock vehicle applications alike
- Optimized electrode design for hard to ignite fuels, such as ethanol
- 1 step colder than OEM (Gen 1 B48, Gen 1/2 B58, & S58)
- Cooler operating temperature than stock plugs
- Resists preignition better than stock plugs
- An excellent match for Dinan ignition coils
