NGK Spark plugs

I don't have to change my NGK plugs every year like Ken. When I used Champs I had plug problems but the NGKs have been in for over 6 years with a lot of miles and all 8 run and burn perfect. G.M.
 
I change my Champions every 10,000 miles only because I read that somewhere once. Never any trouble past 39 years.
 
6 yrs on a set of plugs on a vehicle thats used a lot,I WOULD CALL THAT BEING CHEAP. For the $15 or so its cheap insurance i dont get stuck on the road. LOL ken ct.
 
I'm not cheap, just thrifty. Why change plugs when the NGK plugs just keep working. They are not going to all stop working at once. I have never had a NGK go bad yet but have been on a tour where a friend with a 47 Ford had ignition problems. We just happened to stop in a lot across the street from a Napa store. He walked over and bought a new set of NGK plugs, installed them and problem solved. If you ever get your car running stick the old NGK plugs you say you bought back in and enjoy the ride. G.M.
