It may be optimistic to think that I will have my Cobalt SS/SC for 100000 miles....but just in case....

For those that haven't pulled their spark plugs or looked at the how-to, the plugs sit deep within a well at the top of the engine, threaded into the aluminum head....

Seeing that, I thought I would NOT let those spark plugs sit in that block the next 100000 miles and effectively attach themselves to the engine block. Can you imagine what kind of engine disaster it would be if the plug seized to the block?

So, preemptively, I pulled the plugs, and applied anti-seize to the threads. Very easy to do while the engine is young....and replaced the stock plugs.

Excellent advice for anyone who intends to keep their car for a long time. Because if you leave those plugs in for 100k miles they WILL be long life - as in never coming out *L*.

You shouldnt leave your stock plugs in for that long anyways. 110K is way to long, bad idea

I change my coppers every oil change, because they get dirty, and a cheap as dirt.

I dont ever use anti-seize ....it always makes the plugs harder to remove imo . Ive never had a prob not using it on plugs .

The say 100K miles if under "normal" driving. But NOBODY drives under the normal driving conditions. The longest you should go before changing plugs is 50K. Any longer then that and you will probably start to notice the plugs fouling. I usually change my plugs every year just to make sure they stay in tip-top shape.

Wait...the post from SilverSS/SC...anti-seize makes the plugs HARDER to remove? That seems to be the antithesis of anti-seize.

How could that be? The stuff I put on said it was rated to 1600 degrees. No joke.

I think Antiseize consists of fine aluminum, copper and graphite...it should stop the plugs from attaching permanently...what makes you think the opposite should happen?

I use it each time I swap out plugs. Never had an issue up to this point.
