Just got my 2010 MKS ecoboost and love it so far.
I want to ask because it has 85,000 what kind of system update (flushing, replacing, testing) should i do to get this thing running the best it can.

You'll love the ride!
Unless you know how it was driven (or beat on) and have the service records....Beyond the obvious, I'd recommend a low volatility motor oil (Amsoil or Pennzoil would be my first choices), check-clean-gap plugs (motorcraft OEMs are fine), and to clean as well as change fluid in tranny and PTU. I'd ask a ford dealer to see if the ECM software is current and have that updated... at least on the SHO there has been an update in the last year. The same might apply to your SYNC. Consider BG service also for the particular needs of a GDI engine.
Check the cabin and seat HVAC filters too.
Check the TSB/recall list posted here... and/or register your car with FMC to check and be sure all have been applied. I have found that I often found out about these from FMC before my SA knew of them.

5,500 rpm is fine, no problem. Once tuned, raising to even 6,000 rpm before the shift is not a problem.

.035 is OEM gap... You are correct. If you tune you should regap to .028-.030salsathe4th said:SHOdded said:Is the dealership saying that? Or did you read it somewhere? My impression was that people checked the gap from factory (0.030) and it did not need to be changed. Folks?
the amazon page you linked says that those are gapped at .035 and that they fit my 2010 mks

IMHO... Yes, especially with 85K miles and no records. The hassle is FMC saying not to do it on the PTU until 100K miles. There is not even a drain plug on the PTU...so a change is actually a flush and repeat several times process, or taking the unit off the car and dismantling to clean. My dealer won't do it because if they do Ford says their service was done improperly and leaves the dealer liable... But the service techs all seem to agree that no fluid will last that long. Failures aren't common, but when they do the fluid looks like very thick chocolate than is hardley a liquid. Many change the RDU fluid at 10K-25K intervals or annually.salsathe4th said:BiGMaC said:.035 is OEM gap... You are correct.
