I use NGKs in everything - imports, domestics, trucks, high performance engines, all of it.

I buy cheapies and replace them often. May not be the best route but I always have good plugs!!!!

keep your gm vehicle all gm. its not like ngk's are going to work any better. index them if you want the most out of them.

no body uses spark plugs? i might use oem ones.. just very curious abt E3 it was in 4 wheeler, off road magazine.. they say its the best plugs period. so i dunno.. i might use that on my 80 gmc. but i want something to last on my 03 silverado.. shes sees alot of highways.. i average her 22 mpg on long trips. just want to try 23 if possible.. already have k&n filter in, uses mobil one oil, and soon coming 1 inch spacer.. been thinkin alot abt headers but thats later. as of now.. oil change, spark plug, wires. so may 1st is when i get tune up kit.. wanna hear everyones opnion abt which plugs. i like everything premium on my trucks..

Ac Delco whenever possible..

NGK's are very comparable in construction to the AC's, but I like the AC just a bit better... Rumour has it that NGK is now making AC Delco's...

as a auto mechanic who sees the problems with home done tuneups with wrong brand plugs in newer rides these days. ( ACDELCO IN GM ) AND BRAND SPECIFIC IN ALL THE REST. its not worth the time and hassle traking down skips under load and crapy performance when it all leads back to the wrong plug.

I have NGKs in my '99 T/A and never had a problem with it. I have yet to see someone making lots of power with an LSx engine running anything other than NGKs, actually. I know it's not 100% relevant to the topic at hand (older SBCs), but the whole "'domestic' plugs for domestics and 'import' plugs for imports" doesn't make any sense to me.

i see plug to running problems all the time and its worse on vortec and up gm engines.

the time and money put in to building a stock motor from the factory via the enginers and getting it to run the best with that brand and model plug is what its all about these days.

for example. my 96cc 350 vortec was good. i did full tune up. and then at highway speed under load with convertor locked up in od i had a surging skip. swaped out namebrand diffrent plugs. then installed the acdelco factorys and what do you know it was gone. so even me a mechanic i am a converted man.

plus the hassle to get to some of the plugs these days do you realy want to do it all over again cause you have a crappy running ride after tuneup?

My experience is mainly with the LSx stuff and the LQ4/LQ9 engines. Just about everyone I talk to on LS1Tech and LS2 run NGKs, with no problems at all. Really don't have much experience with '97 and earlier GM engines, or SBC stuff, but I don't know...just never had issues with NGKs.

I just hate seeing people run the Bosch +3 and +4 junk in their engines.

the inside of each brand plug the porcelain are different shape specific to the engine it was designed for. for the most compresson they spent tons of money & time to design the their own plugs for their engines. ac delco for gm
bosh for german cars, autolite for chysler , motorcraft for furd, ngk for jap/asian. stick with what was designed for your applcation.

since most people voted for ac delco. im goin to buy a ac delco tonight. thanks for ur help.. almost made a mistake of buying E3. thanks again ya'all!

AC all the way. I have had problems using other brands of plug in Chevy 350's twice and figure it's not worth the heartache to go through again.
