Going with 3xNGK 6150's (same as before) and 6xMOTORCRAFT WR6135 .. crossing my fingers.  Hope this is not a actual coil issue or weak o2/wideband thingy ..

I do not want to deal with the dealership with no codes ...

If it was me... I would buy six... what I don't use I can put away for when it's time to replace them.. at $6 a plug it's cheap insurance..

Will a meth wash hurt the plugs !?   should I be replacing them every 10k?  (that's how long I have had mine ..)

one last hail mary.  I will check the CAC..   it has never been a problem before... BUT it has been run HARD and above stock boost levels so it *could* be getting more than normal oil and goo in the bottom and eating it on high rpm runs. 

I will see about 'sticking' it today or tomorrow...

to be clear normal driving is perfect and strong.  it is under high load and high rpm the issue crops up.

The extra stress alone from the drivetrain on a Tuned vehicle should be changed more often preferably @ 12K intervals .IMO. for added reassurance purposes.  Z
So to better answer your question "Yes"
@ the end Fresh plugs,fluids=better performance.

Where and what does the boost solenoid look like ?

From Brad ""Chris go check your vacuum hoses around the boost solenoid, specifically the one that leaves the solenoid and goes to the intake pipe  or charge pipe. It looks like you are overboosting.""

is this some thing similar ?

thankx in advance..

I assume this is what is being talked about

If tuned:  Take note of the strategy code as you return to stock (including 3 bar MAP to 2 bar MAP) -> take car in & get it serviced -> check strategy code when you get car back -> have tuner update your tune if the strategy code has changed -> reload tune -> ENJOY!

Thanks SHOdded,  i thought that might be it but wasn't sure. 

NEXT mystery ::
http://www.rockauto.com/en/catalog/ford,2010,taurus,3.5l+v6+turbocharged,1445050,exhaust+&+emission,oxygen+(o2)+sensor,5132

Brad says my primary O2's are sketchy ... but on the RA link above the closest thing i find to primary is ''upstream''.   any ideas?  since this is a race rig and DD i will pop for bigger cost/better quality pieces but i do not know which parts i need.. and to be honest if i should just replace all of them since i will be under there.

So far we are
6 new plugs to replace the 10k old NGK 6150's
6 new boots for the COP
2 new O2's for maybe 4 for good measure
..

thank you all in advance.

Primary = upstream
Secondary = downstream

When in doubt, go oem.

Call up one of the online dealers for all the parts you need, discounted.  Levittown Ford, Tasca, and AutoNation of White Bear Lake are tops in the trade.
