I want to add NGK TR55 IX and GM Red Performance Wires to my 2000 coupe with approximately 45,000 miles. I have never changed plugs on a Vette before. I would greatly appreciate any feedback that anyone has to offer. Or if you have any suggestions on other plugs and wires. Where is the best place to get the plugs and wires? Can anyone also tell me what it means to index your spark plugs? Thanks!!!

 

Its not bad, you just have to take your time. I had my plugs/wires changed within a hour. The rear plugs are a little more difficult but will come out.

I found plug wires on Ebay and bought the set of Accel wires for $30 shipped new. I like MSD or Accel myself. You could order them thru your local parts store also.

By index the plugs I think they mean Gap them. Even though they say they are pre gapped, I would double check so you dont have to do the job twice. Remember to use Anti-Sieze on the plugs and to wait until the heads are cool before you start taking plugs out. Otherwise you can pull the threads out of the heads.

 

 

If you google indexing spark plugs you will find many explainations, this one I adapted from wiki...

Indexing spark plugs
A matter of some debate is the "indexing" of plugs upon installation, usually only for high performance or racing applications; this involves installing them so that the open area of the spark gap, not shrouded by the ground electrode, faces the center of the combustion chamber, towards the intake valve, rather than the wall. Many believe that this will maximize the exposure of the fuel-air mixture to the spark, and therefore result in better ignition; others, however, believe that this is useful only to keep the ground electrode out of the way of the piston in ultra-high-compression engines if clearance is insufficient. In any event, this is accomplished by marking the location of the gap on the outside of the plug, installing it, and noting the direction in which the mark faces; then the plug is removed and a soft copper washer is added so as to change the orientation of the tightened plug. The orientation of the electrode gap is changed by using a thicker or thinner washer. This must be done individually for each plug, as the orientation of the gap with respect to the threads of each cylinder is random.

Now, if you read all that, you may wonder if it would be worth the trouble to get an indexing kit with the various washers and use it.

Or you could just use the pricey four electrode plugs out there. At least then you have a one in four chance of the optimum spark orientation.

Either way, it probably won't make a noticeable difference in a n/a motor.

 

I changed the plugs and wires on my 2000 and used Magnacore Red 9MM wires from revtech

I was very pleased with the results!

 

i went with MSDs.

 

Whats MSD?

 

Oh No..

 

Did the same job about 3 or 4 weeks ago. Used Delco Iridium plugs and GM red Performance wires. Bill Curley has wires for just over $50.
See my post Changing spark plugs a few tips for detailed instructions. BIGHANK

 

A swivel socket and a couple of extensions will make the job easy.
