I recently bought my truck. It has 101k the previous owner hadnt changed the plugs and wires yet.. taking suggestions on whats best for the 2002 5.4L...

 

good luck. when i changed the plugs & wires in my 99 4.6 changed @ 86k i had to shell out like $120 just for wire. i almost cried.

 

Forgive my ignorance, but I thought an '02 was equipped with the Coil-On-Plug system.
If not, then the best wires in the world are Magnecors, but they ain't cheap!
If your ride is COP, then Bosch P+2 plugs are very nice.
If not COP, then any good brand of double-platinums are nice.
