5.0nly

And wow, the power delivery is addicting. My 5.0 would hunt for gears constantly on certain drives but the eco stays in 6th and still gives you great torque. I just brought it home after a 10 hour drive and I can defintely see why some folks like this engine. Truck is a 2013 FX4 with 298,000 on the odo. That being said, I did get a check engine light and a couple of misfires at WOT only. Should I go ahead and change the plugs? Does anyone have any part numbers for the plugs & tools? What do I torque it to? Thanks!

298k???

Drill the weep hole in the intercooler. Change your plugs every 30-50k with the ford SP534s gaped at .030
I believe they are torqued too 11ft lbs.

298k miles? Or kilometers?

I thought the '13+ trucks fixed the weep hole mod? Anyone know what socket I need?

Miles. Got the truck for 5 grand. Fully loaded 2013 FX with the appearance package. Good deal?

For $5K? That's not a bad deal, but that's a boatload of miles. The saving grace is that those pretty much have to be almost all highway miles, so it's not like it was sitting around idling or running stoplight to stoplight.

$5k is a great deal. My buddy bought a Lariat with the 5.0 and 212,000 miles on it for $12k and I thought that was even a great deal.

300,000 miles on a first generation EcoBoost engine is extremely impressive. I'd love to see the service history on that one.

No they did not, I have mine drilled.

Spiky

No. Maybe in 16-18 somewhere, not sure. You need a drill bit.

Put a nice tune on it and the smile on your face will be permanent. I would definitely change the plugs, coil boots and drill a weep hole in the CAC. I would also clean the MAFs and TB as well.
