How to Change 1998 Mark VIII LSC Spark Plugs

Haha. They have the copper 764s, but I'm looking for the double platinum 764s. Yes, they apparently have the same part number?

For right now, I'm just going to do the fuel filter, and throw the K&N in. All this talk about possible backthreading and other fun stuff has temporarily deterred me, lol.

Then you want APP764, not just 764. Also I hear good things about NKG. Not so much years ago, but they are a great inexpensive plug now.
