iridium ftw

 

i change my plugs at every oil change. cheap insurance, i cant afford a misfire while spraying

 

that might be a little excessive

 

$9 every 5000 miles is not gonna kill me. lol

 

just buy some iridiums. they are good for awhile. on normal use i believe they are good for 100,000 miles

 

Octane boosters or fuel additives will cause a red tip to form on the spark plug.

I'd stay away from additives.

 

copper is the best conductor for spark, they are 8.99 for a pack of 4. gotta keep the car running good

 

personally i see no reason for using copper plugs. thats just my opinion

 

Copper is the only way to go. Especially in boost/nitrous applications.

 

better spark means better nucleus of the flame, which means better hatching of the flame, which means better propagation, completing the burn as best as possible

 

ive used copper, platinum, double platinum and iridium. i will always go iridium.

 

If you really think that's better...

 

that may be so, and do what you feel is right. i am just saying that copper is the best conductor

 

to each their own, my car just runs the best on iridium. thats what i have found out.

 

proper gapping is essential

 

I love my autolites.

 

.035 seems to work for me. on copper and platinum i used .032 though

 

**** on my autolites i used .38

 

.36 works for me

 

1 step colder? also depends on your pulley what gap you bring it down to

 

Yea one step colder...

i had a 2.8... I think it was .37 actually....

 

that sounds about right for a 2.8 give or take.

 

I had similar problem but was orange like rusty water, I think it was because I was running too much timing. Haven't seen it again.

On second look, mine happened while running at Hallett OK, you guy's have some weird crap in your fuel?

 

change where you get your fuel, and don't go back..

 

so should i get step coolers AGAIN. and what should i gap them at for my 2.9?
