xandraxal · July 29th, 2012, 02:19 PM

Ngk tr6 gapped at .030

jstang98 · July 31st, 2012, 03:49 AM

+1, but id run the gap a little larger if it was me.

xandraxal · July 31st, 2012, 12:31 PM

Yeah you make a point. I'm also not a fan of nitrous either. OP run a copper plug if you're using nitrous.

what are some cooper ones?

He means dont run platinum plug. And I am of the school that says you dont need plug 2 steps colder until you run 20lb of boost or a 200 shot if nos

Buy a TR6 plug. It should be in an NGK V-Power package. Do NOT run a TR6GP.

Exactly, 100% agreed on that.

jstang98 · August 1st, 2012, 01:38 AM

alright sounds good then tr6 it is now you guys are saying .30 gap what about when its not be sprayed how will that affect drivabilty and if i wasnt plannign on spraying right away would you say for gap with the swap and premium fuel with a tune??

jstang98 · August 1st, 2012, 01:40 AM

and something else i dont get why would one use a smaller gap when running spray would you want a bigger arc because of all the extra fuel and oxy molecules or does that make it weaker cause it has to arc futher???

termi_GT · August 1st, 2012, 01:36 PM

If you run too big of a gap with FI it will cause spark blowout. I run all my FI set-ups with a gap of .028-.032

You won't notice much change at all in driveability.

sharkbait · August 1st, 2012, 02:00 PM

I would recommend autolite 103's

Your going to need to gap them around .030
Worked fine when I used to spray my car.

jstang98 · August 1st, 2012, 11:37 PM

i think i would be more comfortable with a 2 step colder plug, what would they be for NGK and Autolite?

jstang98 · August 3rd, 2012, 03:14 AM

???

1996 GT · August 3rd, 2012, 12:39 PM

NGK would be a TR7, no idea on the Autolites though.

Tang Stang · August 3rd, 2012, 01:46 PM

NGK has the TR7IX and the BR7EF. Motorcraft has the AWSFA-12C and the AGSF-12FM1. Denso has the T22EP-U (does not have a resistor).

My recommendation is to start with a colder plug, make a pull, check the "color" to see where you're at, then adjust heat ranges from there.
