Mileage on plugs for Livernois tune

[Juicybaka]

I’m just about to order “permagrin”. With 13,000 miles on vehicle, should I install new plugs too? Thank you

Yes you should. I change plugs every year in my SHO and wife's Escape.

I watched video for removing intake to get at back plugs. Looks like total PITA, something I’m not going to want to do every year. How much would dealer charge for this? Thank you

 

[SHOdded]

Likely anywhere from 300 - 450 ... USD.

You dont have to remove anything on a SHO to change plugs in it.

Some of the wiring harnesses may have to be moved for the back three plugs. Other than that it's fairly simple.

Back is harder than the front but I was done in about an hour. Had to move some wiring around and I also removed the pipe that goes over the top of the motor to the back turbo area

I've found that this is by far the easiest transvers mounted engine to change plugs. With the right wobble sockets and extension I didn't have to remove anything and just pull the sockets.

What is everyone's opinion on spark plugs - what brand, type, etc...? I've seen commercials for those "E3" I think they're called with the 3 prongs for a more efficient burn. I want to change mine again just to stay on top of all my mods.

Motorcraft SP-534s are all you need.

 

[SHOdded]

If you want to try a different plug, the SP542 might be a candidate, it is 1 range colder, I believe, than the SP534.

I'm curious about this. When I had my Focus ST running a Cobb Tune a one range colder plug was necessary but I never really understood why. So what benefit is there to going colder?

 

[SHOdded]

No need unless you do a high hp build like bpd's. He uses the NGK plugs, or was at last report.

Seems like your right around that time as we suggest changing them every 15k miles or once a year

 

[Jeff2017]

Use OEM Motorcraft plugs. 13k seems like a low mileage but if you can do them in an hour, it might not hurt.

 

[Juicybaka]

Is $760.00 fair price including alignment to install springs?

Sounds about right to me so yeah thats good!

I changed the plugs a couple of times on my 2011 SHO, this weekend I'll be doing them in my 2016, the back plugs are more difficult but no big deal, no need to remove anything.

Usually 4 of them are easy and the last two are the harder ones
