i have always had good luck with using Ac Delcos and prefer them over champion by a long shot. some people are into those e3's or whatever but i was always taught that electricity takes the easiest and shortest route so i wouldnt see how all 3 posts would fire at the same time. im no spark plug expert, i always just throw some ac delcos in and run

I run the accell header plugs u can buy off the autozone shelf for 30 bucks and they seem to work great im not complaining but ive heard acdelco plugs are pretty good if u wanna use them



and e3s im sure they work good but who really cares im not payin 60 bucks for a set of plugs lol no offense to anyone who uses them

Personally, I wouldn't use anything but ACDELCO plugs in a GM engine. The next step up from conventional plugs are the ACDelco RAPIDFIRE® Performance Platinum Spark Plugs.

I second the AC Delco in gm engines. Thats what I run in my Olds 350. R46SZ part number.

I've used those E3's and they did improve my combustion, i could tell because my car was running a lil bit rich but you couldn't tell with the E3's when i slapped in a set of acdelco's you could see the smoke coming from the exhaust, but they are expensive, I use autolites copper core, cheap and they seem better than ac delcos IMO

I have a question on this subject my 350 has auto lite plugs in it #26 so I went and bought the same ones but I haven't installed them I asked them to recommend plug brand to me for a 350 Chevy and they couldnt cause there is to many different plugs for Chevy 350s so they didn't know which ones could be best so I just settle for the ones I already had on the car can anyone recommend which name brand and a part number plugs i can use on my Chevy 350.

I use AC rapidfire #1 platinums. I noticed a marked improvement over the standard R43ts plugs. They are spendy but on a properly setup engine they last 100,000 miles. My engine is a Gm Crate motor called a K block I am running a GM 92 vette roller cam and lifters and a set of 1.5 roller rockers, a Edelbrock performer EGR manifold, with a Nicely tuned Q-jet.

AC Delco is the recommended plug brand for Chevrolet. Just get the cheap copper core ones. They should be about $2.09 a piece.

I've used AC Delco's, Bosch, Autolite's and now NGK's.

I prefer the NGK's but really couldn't tell much of a difference between any of the other's.

I personally am not sold on AC Delco stuff anymore. Used to be if you wanted a quality, OEM style part, you bought AC Delco but anymore they're all crap, overseas made junk anyway.
