Plug Changing

[Mark #2]

What is the general consensus on anti-seize on plugs these days?
Haven't put in on in the past 7 years and the plugs haven't blown out, but it still seems like a good idea with AL heads.

I use it for heat transfer. Does it help transfer from an engineering standpoint? Engineer dude? got beer?:beer:

Way too many assumptions in the thermal model.

Porsche guys, many PHDs, for the last 30 years still argue about this.
Metal to Metal is the best, but the resistivity and total area at the interface between the two is where the thermal model brakes down.

The Porsche racing guys put it on as I did so you can get the plugs out without galling if needed when hot.
We ran big Weber carbs and fouled plugs regularly.

Don't be sceered! I like the copper grade studd myself. I do a lot of plugs dry but I also seize the high heat situations for transfer. I liken it to mounting voltage regualtors and amp chips to heat sinks and chassis etc. Without the transfer compound they burn up. Fo shizzle, wheres your brews? Miller as usual?:beer:

I typically use antiseize on every single bolt I reinstall when I work on my vehicles except on spark plugs. I've used copper antiseize on a previous change and don't care for it much at all. The thing I don't like about it is that the next time you go to remove and reinstall the plugs the remains of the antiseize have dried and is all crumbled and doesn't allow for a good installation. It ended up taking me hours to clean the old antiseize out.

If you don't like the copper anti seize. At least use a drop of oil/grease to get a true torque.

I've always used it-not the cooper stuff just the Permatex anti seize
