buying spark plugs

[colonel6632]

so i did a little searching, and NGK is the way to go.

but i heard using iridium ones may help my gas mileage since they burn hotter...

if i get hotter burning plugs, will it help anything.

NGK makes 3 plugs for the ecotec.

g-power platinum
NGK platinum
Iridium IX.

which ones are the best?

NGK platinum

I bought the AC Delco Iridiums, which are the same iridiums because they are manufactured by NGK. I don't remember exactly what the advantages of iridium are supposed to be, but back when I was doing the research, they're supposedly better than platinum.

I did get about 1mpg better after changing them, but I also changed all the fluids and filters at the same time as doing the tune up.

i went with autolite iridiums not bad

i have NGK's but i have a 3400...

[01OldsAleroGt]

i've heard ACDelco Rapid Fires are great for the 3400 is that true ?

[Cliff8928]

The original rapidfires were good. I don't think the new ones are much more than a single-platinum plug.

You'd probably be best off with the ACDelco #41-101 Iridium plugs.

search button ftw
i used it and now im get iradium plugs in my eco

[pawzbear]

if you want bang for your buck then get an autolite, they are reliable in domestic vehicles. I used to run them in my cobalt but now i run NGK iridiums.. I dunno about that hotter thing though, b/c mine are 1 step colder..

Ecotec 2.2 L61 spark plugs
NGK Iridium LTR5IX-11: Stock replacement
LTR6IX-11: One step colder (Boost/Nitrous)
LTR7IX-11: Two steps colder (Boost/Nitrous)
