    It's all marketing hype. Your truck was made with AC Delco, you should go back with AC Delco... Not Bosch, not E3... Delco plugs were made for your truck.

    AC's have always worked best for me too. I tried Bosch plugs years ago and pulled them out hours later and tossed them! Wasn't even worth my time to return them.

    If they have the Rapid Fire plugs available for your year, get those!
    *they were a modified design plug w/ a tapers electrode and ground strap. Made my old Pontiac run smoother, more responsive too. Depending on what plugs came in your truck, and whether they still make them -- if they do, but them!*

    I ran a set of E3's in my 07 4.3L and they performed as advertised. However, after 20,000+ miles they started to cause the engine to misfire. I went back to OEM plugs and haven't had a problem. I can't recommend the E3's.

    Here is my theory. Just a theory..

    E3, Split Fire, Quadra Fire, ect...

    They are all the same. Look at electricity. It takes the path of least resistance. Hence... They may work great in the beginning, but after they start to wear, they will take the most worn easiest path. Fire to 1 spot. Not multiple. Causing a weak fire, or missfire.

    IMO

    no good.. stick with stock or NGK's... these things are garbage... have seen sooooo many people have problems after installing these plugs - and once they switched back, problems solved...

    They have ther qualitys i guess but call me old faschioned, i prefer the old school stuff rather than the new WONDER things. A good spark plug then is still a good one today. [FONT=arial, sans-serif][/FONT]

    Electricity takes the path of least resistance, maybe once in a while it will jump around between the other electrodes, but I bet you'd usually find it hitting the same a majority of the time. So why not use the plugs that the engine was engineered around to begin with? After all, AC Delco has had a good rep. for making damn good plugs; they're proven to work!

    Are the NGK's actually the OEM plugs for 01' and 02'? According to Haynes manuals this is what they call for....any chance they got it wrong? I think I pulled out AC's from whomever did the previous tune-up, but they must either not know about the Haynes recommendation or just know better from experience. 100% of the guys at the AA parts where shocked to see this information in the Haynes manual regarding NGK's for a big American V8, vs. an import.

    Just was watching Stacy David's Gears and he actually did a electric test and you could clearly see the electricity going to all the points on the diamond shaped end of the E3, he also showed it sparking in a combustion chamber, they look great hahah but like everyone said they are not wat your vehicle is made to use,

    Also checked with my dealer's part counter and he said they only use AC Delco's in all those years for Tahoe, S10, 1500's etc.
