doin new plugs in the 08 wrx...anyone know if subies prefer any of them? like cold plugs or iridium platinums or something? any help would be appreciated
+1 The stockers should be good for 60k or so. The main adv to the iridiums is the long change interval, which is a big selling point on for subies.how many miles are on your car?
I am even getting those for an old one...(except 3903 part#)+1 The stockers should be good for 60k or so. The main adv to the iridiums is the long change interval, which is a big selling point on for subies.
one step colder seems to be the wrx norm...double firing even on oem is a toaster.These NGK Iridium IX spark plugs feature an ultra fine center electrode that's designed not too thin to ensure maximum durability and life of the spark plug and not too thick for an accurate and consistent spark. They represent the ultimate evolution of spark plug technology and performance. Iridium is significantly stronger than any metal used in spark plugs today. It's the hardest metal used (in fact, iridium is 6 times harder than platinum) which has allowed NGK engineers to design an ultra fine center electrode reducing the voltage requirement for spark.
