Getting ready to install new Motorcraft plugs (standard copper) and was wondering if I should use anti- seize?

Read through numerous posts on the pros/cons.

From what I hav read, this is basically what the pros/cons are.....

CONS:

1. Anti-seize can allow for over torquing plugs as the additive allows for easier torquing. How would this matter if you used a torque wrench?

2. The anti-seize can affect the ability of the SP to dissipate/absorb heat, causing heat/SP/Head problems

PROS:

1. will protect threads and not allow for corrosion to settle in and allow for future removal of SP without issue

Thoughts? For those that are on the PRO side please explain and note which anti seize you use? Is copper based anti-seize the formula of choice for those that use AS? For CON, explain reasons

Thanks!

 

Yeah I can't give you the definite correct answer, but I can say I always put anti-seize on mine. It makes replacing them a whole lot easier. As for torquing, I don't use a torque wrench. I just run them in as far s I can by hand, no tools, then I put a 12" ratchet on them and run them down snug. Been doing that since I got the truck and 20k miles later I have had zero issues. I used the same process on my brothers cars and they have had no issues at all either.

 

I never use anti-seize on spark plugs, on my own vehicles or on customers. I do, however, strongly suggest dielectric grease in the wire boots and connectors, this seals out moisture and makes future removal easier.

 

so one pro and one con.

Dielectric grease I plan on using on plug ends but not on dist cap end. Read that is was only needed where spark plug was to avoid spark from coming out of plug boot.

 

Use grease on both ends and it will also keep them from corroding or the boots getting "glued" on. As far as anti-seize, I never put any two threads back together without it! Yes, copper is prob best for this application. Just be careful not to get it on the electrode. Then I torque to Evan_P specs, precisely.

 

I put antisieze on EVERY bolt, stud, or nut that I install, whether it's something new I'm adding to the truck, or a part that I removed and am reinstalling.

I use it on my spark plugs and don't put a torque wrench on them either. Ain't ever had one blow out OR get stuck, if it was previously serviced by me.

I don't think it would affect heat transfer that much, if at all. Ain't ever had a problem with heat either, and I run my engines hard sometimes.
