I have a 96 V6 M edition MX-6 and I was wondering what is the best spark plugs to use? Also at 60,000 miles what belts should be changed? Thanks for the help!
Smoother idle, better fuel efficiency, and more fuel burnt, so theoretically you MAY get some better performance. You will if the plugs you already have are old.kingnajar said:what advantage does a good spark plug give...? I always thought it was just for starting the engine?
