spark plug question

[caldera]

Hi all,

I have a Magnum R/T with 35k miles and decided to change my own plugs. Having never worked with aluminum heads before, I was wondering if it is a good idea to use copper anti-seize on the threads or just install them dry?

A Predator is in the future and i plan to disable the MDS. From my feeble understanding, the 30k mileage sparkplug change interval is due to the MDS. If disabled, would it still be advisable to change out the plugs every 30k after that?


Thanks from a noob.

Doing a forum search on spark plugs will get you a lot of info.

I use anti-seize on my plugs. Going with inexpensive copper core plugs with platinum tips (e.g., Champion, Autolites) will do just fine. If your engine is moderately to highly modified, or you're using nitrious, you need a cooler plug than stock.

MDS has nothing to do with the change interval.

It doesn't matter what material it's made out of always use anti seize!
