Hey guys what kind of plugs would be best for my 99 4.6L truck. I was
thinking about sticking with the original plugs from ford, are they autolites? advance carries bosch's, autolites and champions, none of which i am a big fan about other than the autolites. thanks...

 

Id go with the Autolites, or Motorcraft. I have a set of Autolite Double Platinum's in my 99 4.6 and havent had a problem with them at all.

Ive heard these Fords dont really like Boshs and Champions.

 

I have a 90f150 and have been using Champions every time I change plugs, no probs @ all

 

Stick with the Motorcraft or Autolite plug. Double Platinums. You won't be sorry.

Stay away from Champion. Not a good Ford plug.

 

I agree, stick with Autolite or Motorcraft.
Champions are really bad in these engines, and Bosch are hit or miss (hear lots of bad stories, hear lots of good stories...)

 

^^^^ I agree. You must use double platinum also.

 

I would stick with Motorcraft platinum OEM plugs. They are the ones that were designed for the motor. I have had good luck with them.

Use Motorcraft plugs. You can get them for about half the price by doing a search on Ebay for: hillisbestdeals. I recently bought a set of 8 plat plugs from him for $24.00. Dealer charges about $6.00 each. You do the math...
