Denso Iridium Long SK20R11 Spark Plug
Part No.: 3297
Spark Plug Product Code: SK20R11
Iridium plugs have an extremely long life as Iridium is 6x harder and 8x stronger than platinum. Because of the strength and hardness of iridium, there is virtually no electrode wear. This combined with a platinum tipped ground electrode, creates a spark plug that is almost impervious to wear even under extreme driving or racing conditions.
