2011 XLT. What is the correct coil pack?

[callwill]

125k on my Expy. Have no idea how long the plugs have been in there, bought it @18 mos ago and it is running great. I have plugs and started thinking that as long as the plugs are being changed may as well do coil packs. Started looking and there are a number of different MC numbers thrown around on some of the seller sites as being the correct one.
Rock auto says brown boot DG521.
Are there any recommendations on aftermarket brands.
The plugs i have for it are MC SP509x.

Call your local ford dealership, give them the vin number, they should be able to tell you.

I'm going to be doing this soon too, but you gotta be sure here, cause from what my trusted mechanic told me, the brown & black boots are NOT interchangeable & will cause some serious issues if you use the wrong ones...

And yea, I agree that you might as well do it all at the same time since you're gonna be in there anyways and it's all part of the same operation

But as Logan said, a stealership should be able to tell you what to use....however, and you probably know this already, but the stealership will NOT sell them to you unless THEY install them, and the quotes I got from 2 different local dealers are both in the $1200 range to do the coil packs, boots & plugs.... f*** that, when you can get the parts from any number of places for WAY, WAY less....

Yours won't sell you parts without them installing? Glad the one by my house isn't like that, actually found out that buying certain things directly from them is cheaper, to buy the oil filter for my expedition is about $15, but at the dealership I spend $8. But $1200 isn't bad for all that work, my dealership charges $1000 just to install spark plugs. Love living in AZ.

Also just stick with ford oem if you can for the plugs and boots, I used duralast ignition coils and they don't seem to do as well as the oem ones that were on there. But if money is tight at the moment duralast is great for lifetime warranties, might have to keep replacing them until you can get better ones like me, but at least the replacements don't cost anything.

Coil packs either work or they don't and you can test them before just tossing perfectly good ones out. They are not a routine maintenance item and will likely last the life of the vehicle. 214k on my OEMs and still going.

however, and you probably know this already, but the stealership will NOT sell them to you unless THEY install them, and the quotes I got from 2 different local dealers are both in the $1200 range to do the coil packs, boots & plugs.... f*** that, when you can get the parts from any number of places for WAY, WAY less....

That's specific to your dealership and is absolutely not the norm. The entire purpose of the parts counter is to sell parts without service. And I live in PA also btw. Find a new dealership.

 

[Logan97]

Ignition coil packs are recommended to inspect and replace as needed every 60,000 miles or 4 years.

Only on certain things, they won't sell separately....for routine maintenance stuff, no problem, other stuff not so much...

And here's a strange one: the parts counter sells the oil filters for $10, and the air filter for $12, which is about what I get them for from da Zon....BUT, their "quick lane" oil change is $130....w.T.h.... I get the oil for $40, so they are adding $80 for ~1/2 hour of labor...nope, not doin that either

They also told me that they would only sell the running boards with an install, BUT only in complete sets of 2 boards, motors, brackets, control arms etc.. all for a measly $2600.... f*** that, since my boards are in good shape, I just had one motor that was flaking out, which I got with the brackets & control rod online for ~$135 & installed it myself

The dealership charges people in my area 150 for an oil change, hourly rate for most mechanics in this area is about 150 and they always round up. That's why I learned how to fix cars and just do it myself. I also save money on parts as long as they're duralast since I used to work there. As long as it's not a major electrical component my expedition doesn't seem to mind cheaper parts.

Don't make it overly complicated. You CAN do it yourself, just be sure to have a broken spark plug remover tool just in case. I bought one, but never used it yet. It pays off to apply anti-seize compound to the plug threads. Coils can go 10+ years without issue. My last set, Accel, off Amazon ~$233 for the set when I bought, lasted ~11-12yrs or ~180k miles before one started to go bad. I've just finally replaced all the coils this year! I've replaced the plugs more than these coils. The only tools you need are an 8mm socket and a I forget the plug sized socket. I would also get a set of extra spark plug pig tails incase you break the release clip, I've had to replace several, even on #4 & #8 cylinders. Watch some YouTube University videos on how to do it. Check out RockAuto for parts, you'll save SOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOO MUCH MONEY!!!!!!! According to Dr. Google the brown boots are longer than black. So measure before you order.

This job will cost you ~$300 for DIY or $X,*** for a dealer.......the choice is yours though.

You CAN do it yourself

This is true, IF you:

A) Are mechanically inclined
B) Have the proper tools & work space
C) Have the patience

If you don't have these 3 things, then you're better off just coughin up da cash & getting a qualified someone to do it for you, it doesn't HAVE to be a stealership, but just someone with experience with this type of work....

Just sayin

 

[ediddily]

No mechanical inclination required for this job as there are no moving parts.
Proper tools, yes. Work space is just standing next to car, or lying on car to get to #4 and #8.
Patience only required when something breaks.

No moving parts is true, but I beg to differ on the rest, as the front 6 packs & plugs are fairly easy to get to, even without removing any of the Air intake parts or others...

However if you are less than 6' tall with somewhat long arms, the back 2 WILL be a bit more difficult not only to reach or see and remove without damaging anything, but also requires carefully removing the above parts and a few others too, something which I think most non-mechanically-inclined folks would have some issues with...

Just trying to give a clear(er) picture of what's involved for those who may be thinking of trying something like this for the 1st time.. not everyone has the skills/temperament to work on cars.. I do to a point, but there are certain more complicated things that I won't attempt....and, as Harry Callahan says: "A man's gotta know his limitations"

 

[ediddily]

I'm your average 6' person and I can easily reach #1,2,4,5 easily, #3 & #6 are just a stretch while still standing, only for #4 & #8 do I require a stool to lay over the edge. I replaced all coils, plugs and #8 pigtail without removing anything. Now that I think about it, perhaps I'm biased as I replaced the stock intake with a performance one that is just a big tube as it gives a lot more room.
Note to OP, replace your intake with a performance one to not be intimidated by all the fancy covers that just have "Ford" plastered all over it and a few more ponies at 3k rpm.

Inspect, sure. "Replace as needed." In your own photo it plainly states: "If damage exists refer to Chapter 5 for the replacement procedure." A fully functioning, undamaged coil pack doesn't need to be replaced. If you like throwing money away, don't let me stop you. It's not actually accomplishing anything though.

Those pages are in the routine maintenance chapter is all I'm saying. Got that book from a ford tech.

Answers for everything except the original question!

SEE POST #10!!! It has pretty pictures too

@ediddily
You are voting for the accell coil kit?

 

[ediddily]

Based on my experience I can only recommend Accel as I'm only on my second set of coils with my entire ownership of this car. The coils I have in there now are made by ECCPP and I don't know their reliability. I got them off Ebay years ago for cheap as a backup set.
