Re: Major problems with 2003 Expedition Spark Plugs
Providing you get the plugs changed before the required interval, let the dealer do it so if it breaks it's on them to fix it, not yours. If you get the dealer to replace the plugs after the required interval and problems arise, I'm sure you'd have quite a fight on your hands. I change my plugs every 25-30K in all my vehicles. No sense in running platinum plugs which can last upwards of 100K. 100K is a LONG time for those plugs to be sitting in the heads, so it's only a guess that something will go wrong upon removal
