Hi i was wondering what spark plugs I need for a 1998 3.3ltr GV as i am getting conflicting information as to what plugs to use.

some say copper plugs others say platinum plugs is there a difference other than how long they last ?

 

the part number is under the hood on the white label

they will be platinum plugs and use champion only.

 

Thanks I will go have a look for white label.

also have to ask why only champion?
