I had 2 cars that supposedly need cap, rotor, plug every 30k. After a while I just do it every 60k with plat plugs and ignore the cap and rotor. I did see some deposit on the cap's terminals and rotor did see some dark spot, but I just sand them off or scrap them off with a box cutter. Didn't have problem afterward. Maybe I would if I run mine to 6500rpm but with an automatic transmission they never run that high.
Did Spark Plugs
- Thread starter MountainManDan
- Start date
I forgot to include spark plug wires, with failing insulation.
My OEM one lasted 150k miles before manufacturer give me a free one along with oil change, plugs, cap and rotor, because somehow there are enough of them failing smog that they want to not get in trouble. The aftermarket one I got for $20 from rockauto lasted 30k before one of them got an insulator breakdown and turn into white powder.
OEM for those only afterward.
I Just Sold Set of Use Iridium Plugs from Original 2005 -2012 Volvo Motors - Marked Ford FoMoCo so why did Ford

I remember those old days, cap rotor wires and plugs every 30k or whatever.
Finally got around to doing plugs on our Toyota's, 105k and 125k. Not sure why, they sure looked fine to me, but eh, I can live with doing that every 5 years. Probably will only do twice. I just have to remember, the air filter isn't rated for 100k, for some reason I can never remember to do that every 30k. For some reason I think the hood shouldn't have to go up before 100k. Odd since I remember the days when 100k was considered "a pretty good run".
