Gonna do a minor tune-up on my '94 4.9L. Went on RockAuto and I see lots of plugs to choose from. Any recommendations based on experience? Do I need platinum? Thanks

 

No. this has been beaten to death recently. Copper corr motor craft. Gap to .044

 

just get plain old motorcraft or autolite

 

Stock copper core Motorcraft came out and went back in and she liked it a lot!

I have a '95 4.9L as well. Stock wires, cap and rotor too.

 

Your truck will eat those plats up in a matter of a few hundred miles, stay away from them.

 

I agree with everyone else. Get the regular copper core Autolite or Motorcradt. Once I got my truck properly tuned and all of the broken vacuum lines fixed, it was ping city with platinum plugs. Went to plain coppers and it ran like a dream.

 

What if your runnin ford racing wires?

 

Still run the copper Motorcrafts

 

gapping to .50 without the timing advance wouldnt be a problem would it?

 

Minor electrode burn but nothing serious, I run mine at 0.05" but timing is at 14deg
