Spark plug.. ?!

[turby]

I have a brand new set of #8's sitting here.

I believe it is just the heat range... But AC Delco or NGK... But I perfer AC Delco.

 

 

BTW, go to napa for the 8's and they can order them for you and have them there within 2 days. I have 54 of those plugs here! and I think Ill try em out when I need plugs again.

 

BTW, for AC Delco rapid fire's you can get #'s 2-4-6-8-10-12-14. 2 being coldest plug and 14 being the hottest.

For GM vehicles, AC Delco and NGK are good. Bosch is bad.

 

Agreed. I use NGK Iridium IX spark plugs, and they made a nice difference. Engine just seemed to run smoother. Just remember if you buy the Iridium spark plugs, don't do any gaping, since they're preset for the right gap size (plus you'll risk breaking the brittle tip).

 

If you still wanna use an ACDELCO plug, I've heard that's just about the best you can go with for your car.

With my name being Beausoleil, I should speak French fluently.....lol But I know little of the language...I really want to learn though.

[Grand Moff Joseph]

Not to add more confusion to the mix, but I've had very good luck with Autolite double platinums...

 

But, if cost is an issue, go with the AC Delcos.

If for whatever reason you go platinum in the 3.4 (read: don't), just stay the fuck away from anything Bosch.

Can anyone comment on the performance and quality of the NGK Iridium series spark plugs? I've been using them for a while and I love them. Has anyone else tried them?

On these engines, your not going to get any gain of out upgrading any part of your ignition system. The power you feel is the power you lost from your old, worn out plugs.
