I have a 99' XLT Triton 4.6 V8 and im due for a full tune-up.
I was wondering on the wires, if there was a specific diameter that i had to get for the engine, or if i could get any size, and what the difference is?, also any recommendations on the plugs besides making sure they're motorcraft?
thanks

 

Motorcraft SP432 plugs. $3.87 each at rockauto.com.

Motorcraft WR5934 wires, $65.79 at rockauto.com.

Do not use antiseize on the plugs and torque them to 28 ft/lb.

 

motorcraft for the win

 

thanks guys. yeah after doing enough research, unless i pay way out of my budget, there's no point. so im going with motorcraft

 

Doesnt a 1999 4.6 have COP"s?

 

Nope.
