I am wanting to change my spark plugs on my 94 348, what is the best spark plugs to get? Any info
NGK is the only way to go. Probably use their newest Iridium IX plugs: DR8EIX Too bad they are not available for the F355.
You should NOT use spark plugs with resistors built in ex. Iridium NGK's (DR8EIX's) , accoriding to some of our forum posts. However Ricambi put them in thier 30,000 mile service kits.
