Tuneup Time 3100 v6 98 lumina

[1979lee]

well at 165k the lumina is running pretty good, but its tuneup time(meaning spark plugs), i pulled the front 3 and there quite worn (autolight platnium 606) got them at walmart . they have got too have like 40k on them(probably more). so iam gonna changem out next weekend. are there better plugs you'all can recomend?

thats what i currenty run., Ive attached 2 pics(sorryass cell phone camera) i took of the current plugs

before i wireburshed them and regapped them. .60 seems like a BIG plug gap...... i'd have changed them but it was late and the parts store was closed.

the last time i did the plugs i did the reacheting strap method, and it f#$%@d my hydrolic engine mount hopefully that dosent happen again

let me know what you all think.

Use ACDelco plugs...

[Highmilagecutlass]

Iridium AC Delco plugs passed every cold start test that G.M. used to validate cold weather starting so now that they are stock in every G.M. product and they dont perform that test any more.

 

The test consisted of 6 cold starts at 40 degrees below zero, when most plugs fouled out the Iridium didnt .

the iridium plugs are quite impressive, not exactly cheap, but they last forever.

No need for any plugs other than stock replacement AC Delcos in a stock car IMO

[RobertISaar]

the recommended ACD plats or iridiums seem to last the longest and give the least amount of trouble.

[Highmilagecutlass]

I agree with Robert

[3pt1lumina]

AC Delcos...Have always run them and have never ever had a problem all of my GM vehicles

[Crazy K]

AC Delco Rapidfire plugs are platinum and do the job, but iridium can be better.... for more money...

[Highmilagecutlass]

When I bought my Iridium plugs they were at least $4.00 each, But those back plugs are tough to get and I plan I driving my Cutlass at least to 400,000 miles so I could justify the cost.

Thanks everyone, Umm WHo Sells the acdelcos the cheapest?

whats the plugs # ?

and what gap shold i set them at , the factory .60?

whats with the big ass gap with these 3100? my former 89 chevy 350 was .35.

but i had a 77 cadillac that was set at .60, we lowered it to .50 and it ran smoother.

 

thanks l:sabeerfall:

[RobertISaar]

the large gap can be run thanks to the ridiculous voltage the coils make, allowing it to jump longer lengths for more complete burns.

 

you can play with the gaps, but it's unlikely you'll find a lot of improvement.

Ok
