Finally got that done today. Had the dealer replace them at 40,000, have 73,000 on it now and put NGK Iridium plugs in. The old plugs looked fine! Now have a back ache, took some Aleve. I am getting too old for this at 46! HA HA In addition, I don't think you need to replace the fluids that often. I had many cars go 100,000 without many fluids being replaced.
