Supposedly if you have a '13 they come gapped correctly at .32-.34

Anyone have a '13 that didn't?

I think Ford recommends 100k for sparkplug replacement.

That's what I was thinking, and heard a lot off ppl that torture this truck do first. My truck idles smooth and pulls great. I just hate the lag time.

That's a turbo charged engine for you. Although compared to my previous TC vehicles the lag is very minimal on my EcoBeast.

However, due to the different metals between the spark plug (steel) and head (aluminum), it is best to "crack" the plugs every 20K to ensure they don't seize in the head, and don't build up a ton of carbon at the end of the threads near the electrode, that can break loose when the time to actually change the plugs come.

Also, it gives a chance to look at the plugs and see if there are any "variations" between the cylinders. I would normally say "and read the plugs for proper combustion" ... but I already know what they will look like ... BLACK ... BLACKER THAN OUR TAILPIPES!

Just imagine what they can look like at 100K.

Before I loaded my custom tune, I bought new Motorcraft SP534's and gapped them to .028. When I pulled the plugs out of my 2013, all were gapped to .030 which is what the factory recommends. I was pleasantly surprised since I had read about so many being inconsistent. When tuned, it's often best to decrease the gap to prevent blow out during high boost. I know a lot of guys are gapped down to .025 and some have to gap at .032. My truck likes .028, idles super smooth at cold start and hot. I just ordered Brisk racing plugs at the factory heat setting and will gap those to .028 and see how they perform. A lot of very good reviews of these plugs on tuned engines.

Every 20k I would change them. I had to fight to break my loose at 20k. All gapped around. 035 replaced with sp534 gaped .030
