anyone know what the recommended mileage for spark plug replacement is? my truck is reaching the 50,000 mile mark and was wondering when you guys changed out your plugs?

every 30K is what I think for says

50,000 miles
Change engine oil and replace oil filter.
Inspect tires for wear. Rotation recommended for
optimal tire life.
Multi-point inspection (recommended)

It depends on the type of plug stockers are prolly somewhere round 60kmls. But for most newer cars the plug life is 100kmls. Good stealership Q, for clarification.

well i just got the new tires and wheels. and put new brakes on front and back in june, oil change is due in another 600 miles.lol so i guess i'll just have to see what's posted next?

On the DuraTech 2.3, NGK Irridium plugs are used from the factory, and should only be replaced by Irridium plugs. The service interval, per Ford, is 100K miles.

That said, I changed mine out at about 80K, and they still had good life left in them. The NGK IrridiumIX plugs are a direct stock replacement.
