ALs or NGK..

[oneil.GTP]

mods are in sig, pry wont drop pulley til later this summer after i get headers so hell with the 104s til then. my question is can i run a range cooler with my setup? like AL 605s? i wanna try to kill some kr without going overboard with the plugs. and im not upgrading my wires, stock works just fine.

copper ftw too, so dont steer me in the platinum area, me like copper. 605s or stock?

thanks

you can if you want but running too cold just loses your mileage.

AL or NGK wont matter really, get what you want.

You think 605s would be considered too cold for what ive got? if so i dont gotta problem with running stock plugs, but if i can get away with the ranger colder ima go for it.

Not really...605 is basically a stock replacement...just a TAD cooler...so since you have a PCM and some exhaust mods...I'd say 605's are just fine.

my car didn't like NGK's, she likes autolites

[blueguy]

These cars love autolites for some reason...even though they are junky plugs...maybe it is because they are an old junky engine?

I need to change the plugs in my winter ride. AL 605's work fine in a stock GTP?

yep ^^^

i have ran both al and ngk with same results. ngk seem to last a little longer IMO

Thanks warbeaver.

That's because they aren't a copper core based plug.

[BoostJunki3]

my car likes both either or but i go with ngk's because al's tend to crack on me...

[SilvaMan61]

never had a problem with my als

[Nickell]

my car loves AL's

Going to install some new Delco wires with AL 605's next week.
