I have a stock 03 C5, I want to go ahead and replace the plugs and wires. I am thinking about the NGK's. What wires should I get with these. Is there anything else I should replace while doing this?:shrug01:
Which one were thinking of using,v-power,g-power or the Iridium IX?I have used the G-power one's in my 454 big block,But what ever one you use make sure you torque them down to man. specs.I have used Bosch also,I also did'nt like them.SILVER50TH said:I read that the NGK 55 is a colder NGK Plug. I thought about Bosch, but my friends with Z06's dont think much of them.

I thought I read that it is recommended that you put dielectric grease on the threads of the spark plugs when you screw them into the heads. Well since the dielectric grease is actually an insulator, is this wise to do? If the plugs aren't suitable grounded via those threads, won't that affect the spark? The whole purpose of the spark plug is to have a hot spark arc across the hot central electrode of the plug to the side electrode above it, igniting the air/fuel mixture in the cylinder. So if the sparkplug itself is somewhat insulated from the head itself, the spark will not be as vigorous as it could be.
Maybe that dielectric grease isn't enough to make a difference, but I think perhaps a CONDUCTING grease of some sort might be better for that particular application.
Is KY the same thing:shrug01: :lmao:98 softtail said:Rich,
No you do not put dielectric grease on the threads of the plug, you would apply a small amount of anti-sieze as mentioned. The dielectric grease is for the insulator and the inside of the boots. Dielectric grease is simply Silicone lube.
