Re: Spark Plugs
Iridium are the best you can get - more spark. They also cost mucho wonga, as as far as I could find out you can only get one size in Iridium. Not sure if you'd notice any difference on the road, suspect v little? May notice better emmisions if it is near MOT time?
If you have money to burn, go Iridium. Otherwise std platinum ones will be fine, and you should notice a difference in performance from replacing worn plug anyway.
