1979lee Posted August 30, 2010 Report Share Posted August 30, 2010 (edited) 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? http://www.oreillyauto.com/site/c/detail/ATL3/AP606.oap?year=1998&make=Chevrolet&model=Lumina&vi=1314043&pt=03435&ppt=C0334 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. lee:dance: Edited August 30, 2010 by 1979lee more info added Quote Link to comment Share on other sites More sharing options...
Night Fury Posted August 30, 2010 Report Share Posted August 30, 2010 Use ACDelco plugs... Quote Link to comment Share on other sites More sharing options...
Highmilagecutlass Posted August 30, 2010 Report Share Posted August 30, 2010 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 . Quote Link to comment Share on other sites More sharing options...
RobertISaar Posted August 30, 2010 Report Share Posted August 30, 2010 the iridium plugs are quite impressive, not exactly cheap, but they last forever. Quote Link to comment Share on other sites More sharing options...

Euro Posted August 30, 2010 Report Share Posted August 30, 2010 No need for any plugs other than stock replacement AC Delcos in a stock car IMO Quote Link to comment Share on other sites More sharing options...
RobertISaar Posted August 30, 2010 Report Share Posted August 30, 2010 the recommended ACD plats or iridiums seem to last the longest and give the least amount of trouble. Quote Link to comment Share on other sites More sharing options...

3pt1lumina Posted August 31, 2010 Report Share Posted August 31, 2010 AC Delcos...Have always run them and have never ever had a problem all of my GM vehicles Quote Link to comment Share on other sites More sharing options...
Crazy K Posted August 31, 2010 Report Share Posted August 31, 2010 AC Delco Rapidfire plugs are platinum and do the job, but iridium can be better.... for more money... Quote Link to comment Share on other sites More sharing options...
Highmilagecutlass Posted August 31, 2010 Report Share Posted August 31, 2010 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.

1979lee Posted September 1, 2010 Author Report Share Posted September 1, 2010 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: Quote Link to comment Share on other sites More sharing options...
RobertISaar Posted September 1, 2010 Report Share Posted September 1, 2010 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.
