Hello all,
Yesterday I stopped by the dealership and talked with one of the lead mechanics about my 93 Explorer. What I talked to him about was that me and a friend pulled the left cylender head off of the Explorer to find a 0.5" x
0.25" hole in the exhaust valve with a crack developing towards the valve stem. We chitchatted about it, but before I left the mechanic told me when I put new ignition wires and spark plugs in (the ones on there are corroded pretty bad) that I can only use Motorcraft/Ford based ignition wires and plugs because those are the only ones that will work and others like Bosche or other brands simply won't work at all.
Is this true? Do I need to get Motorcraft branded ignition wires and plugs (nearly $90 total) from the dealership only or can I get solid, reliable, equivelant ones at NAPA?
