Contour Enthusiasts Group Archives Forums Modifications Forced Induction daily driver nitrous plugs...

i did a little searching and found NOTHING...

okay i found that stock heat range should be fine just make sure the plugs are copper or iridium? i am only going to run a 35 shot and MAYBE a 50 shot if something catastrophic doesnt happen with the 35.

?????

You should NOT run the same heat. You want a step colder. If you have a V6 you will want to use NGK TR55's

i thought i read i should be fine on stock heat range with just a small shot. i should just decrease the gap from stock. i guess not?

TR55's it is then.

i always wondered how a contour would run as a dd with copper plugs and not 2x platinum?

My car runs great, and I've got the NGK TR55's.

My question is, why wouldn't you just go a step colder if you're already changing the plugs?

i was just asking but its all good now...we shall see how she runs tonight hopefully...

well it runs good. at least i think it does. i only got to get into it twice both in 3rd from about 4-6g's. everything seemed to be fine, but i didn't push it to much cause it was pooring down rain, and you dont have much control over a car with 4 year old bald tires/nitrous/rain!

Why not?

On anything larger than a 50-60 shot go a step colder and close the gap to at least .045.

On my homemade wet kit I had, I ran stock heat range copper Autolite gapped at .045 and it ran just fine....until other issues arose.

IMO, 60> stock heat ranger, with a gap of at LEAST .045 will be fine.

The guy who helped me with my kit (a highly respected Fox body guy back home) is where I got my 411 from. He also said from what he seen (for whatever reason) Shell gas was the best for the gogo juice, and also (I can't remember specifics) that he said Delco plugs were the best plugs for the juice (this was really before the NGKs became a 'mainstream' plug).

Stock heat range plugs are most definitely okay for a 50 shot or less.

Make sure they are copper or if you want to pony up the cash NipponDenso Iridiums. Don't bother with NGK's Iridiums and that's rare coming from me as their other plugs are good.

For that matter Autolite has a new line of dual tip Iridium plugs. (Extremes)

Make sure to close the gap up a bit. .045 should be fine for that range.

sorry to bring back on old thread, But what plugs are they?

TR6's are not listed on the NGK website. They have:

V-Power TR55
G-Power Platinum TR55GP
Laser Platinum PTR5F-11
OE Laser Iridium ITR5F13
Iridium IX TR55IX

Im guessing it is the Iridium TR55IX
