Iridiums 1 step cooler

 

[gixxer750]

NGK 3330 stock number. The plug of choice for high horsepower mk4's. It got rid of the idle miss that I had with autolites.

HKS Platinum R.

 

[bowsercake]

Autolite 3923 coppers. After doing alot of searching I found out that those ones were good for me. I will probably be running some more boost later so coppers arent really an advantage right now but I don't mind changing them ever 20,000 as I don't drive too much.

btw, copper can ignite at higher temps than iridium.
