Just as a kind of guide but much of it is true.

Just when you think you know it all, you find out you don't.

Hmmmm.

And no mention of clocking the plug with different thickness gaskets.

And he did not even mention what makes the plug hotter or colder.

Silver,

I used to waste a lot of time clocking my plugs and for the most part I never noticed enough difference to make it worth the spacers and time it took to do it on a regular car. I did it when racing but I also used a very high output ignition system.

True, you will not notice it with the seat of the pant dyno. However if you are looking for that extra .01 to .05 seconds at the dragstrip then it's worth the trouble.

Went to the end so I know the butler did it.
