what plugs to use with a SC

[MightyMaro666]

i am running a 98 Z28 with a vortech supercharger with 9 psi and its aftercooled, but im getting ready to do a tune up on it and im not sure what plugs to get, they say i should run a colder plug because of the SC, what is a colder plug. any info will help.

Most guys will use the NGK- TR6 plugs. They are gapped at .035 instead of the normal .050, which makes them burn cooler.

I have used the NGK plugs for a few years now and I am very pleased with them.

What about autolite 106's

Do the autolite 106's work well on supercharge application. When u gap the sparkplug down to about 40 instead of 50.

Exactally what I ran on my 94.

I used to run the AC Rapidfire #3 on my old Powerdyne supercharged 93 Z28. I never had any problems at all. And I left the gap opened up at .045 because I was running a Jacobs Ignition box which needed the bigger gap.

That was my choice as well, except I used an MSD6A. Worked well.

I use NGK TR6. They are a cooler plug and resist detonation because the ground strap and electrode are shorter and dissapate heat faster. I've never had a problem with the NGK's.
