2.3L ('02-'11) Time to change plugs on my 2010 2.3 with a manual tranny.

The manual does not list the original equipment plug number - why? Did the truck originally come with platinum or iridium? I have 100,000 miles but I don't know if the plugs in there now were original or not. What would be the best choice and what did the truck come with?

 

[Dirtman]

It came with double platinum, use double platinum or iridium. It will chew up single platinum or copper plugs very fast. Motorcraft or Autolite brand.

I only see four spark plug wires on the 2010 2.3. Why do some sites list 2 plugs per cylinder?

The old 2.3 Lima engine had 8 spark plugs (Pre 1998). You have a 2.3 duratec, completely different engine.
