G'day all. I've got a service coming up pretty soon, and I'm thinking of replacing the plugs at that time. Has anyone got a preference, or experience with particular models they'd like to share? :) From what I've been told, the Bosch are the way to go, but a little costly...

Thx

Just had my AU XR8 serviced. Changed the spark plugs to the new NGK Iridium (noticable difference from the Motorcraft crap). Platium plugs are on the way out and are being replaced by these new Iridium plugs. Go the NGK web site (US) and read about them.

Just don't use splitfires, I have been involved in some dyo testing and they actually losted power. If your chasing an edge u could use indexing washes which allow u to use different size washers to get the spark plug facing the correct way in the combustion chamber.
