Well, I have 13K on the factory plugs, so time to change.
I decided to try out the Bosch Platinum +4 plugs ($50 !!)
Anyway, I start pulling the original Champs out and notice the center
Porcelain in the Champs is Bright Red,???? I have never seen anything like
this, I have seen shades of dark orange, light brown, but never a RED like
this!! Every plug I pulled out was Red. Is this from fuel additives??
I have only used additive twice. Anyway, I have a nice Hi-res digital
picture off the plug, I'd like to send it out to you all and get your
comments after looking. Who wants it??

Took me about 45 minutes to change all the plugs, very easy.
Best thing to do is disconnect the electrical leads from the Coils.
This makes it very easy to pull the tubes straight off the Plugs.
Another thing you will have to do is use a screw driver and pop the clip
open that secures the cooling system lines. After that you have full access
to the plugs. Make sure you use a real Sparkplug socket with the rubber
thing intacted. It makes the job very simple. Tools needed are a flat
Screwdriver, 10mm socket(for tube removal), 5/8" sparkplug socket, ratchet
and 6" extension.
 
I installed the +4 plugs and so far they are working fine, no complaints.
No noticeable loss or increase of power. Runs smoother.
