    Default $2 or $12 sparkplugs?

    I just priced plugs for my 2001 Impala 3.8--- at autowarehouse.com
    they range from $2.30 to $12.50 each.

    This isn't a job I want to do more than once [jack a frigging engine
    forward to change plugs? sheesh]-- but I also hate to spend more than
    necessary.

    Can anyone point me to a comparison of plugs to see what the real
    differences are?

    The car has 80K on it- is now a second car & does mostly city driving
    but will be the 'long trip' car, too, so it will be called on to do
    highway driving a few times a year.

    Thanks
    Jim
    [Actually- how many folks would change plugs and wires on this car
    when it is running fine today?]

    Use the AC Iridium plugs about 7 ea. from Napa, or Autozone.

    Any of the Iridium plugs should work well and give you another 80k miles
    easily. NGK, Denso or AC-Delco. I would pick the lowest cost of those
    three. I would also stay away from Bosch Platinums as the tiny center
    electrode is reported to give problems on some applications.

    $2 plugs for your car are likely to be conventional and will work fine
    for a shorter life span, probably in the 15k-30k range. Platinums are
    the next step up in service life and Iridiums are the longest lasting.

    Definitely go with ACDelco plugs. I put NGK's in my old Bonnie's 3.8, and it
    lost gas mileage. When I got my new Bonnie (1996) I used AcDelco and she
    runs great, and gets around 28MPG on the highway, and that's with the
    supercharged engine. I went with ACDelco wires as well.

    You can't go wrong using what the factory used.

    As long as it's running fine, I probably wouldn't mess with it. Plugs and
    wires will usually give you some indication when they need to be changed.

    The plugs in my car are rated for 100k miles. At 110k, the car was in the
    shop so I figured I have the plugs changed at the same time. The
    difference? None. Same easy starting as when it was new, same fuel
    mileage. As expected, a wire broke while Bob was changing the plugs. He
    said it is common for the ones on the rear trying to pull them off the old
    plugs. Worth it? I guess since the car was in the shop it was convenient
    and now they will last me the life of the car. My 91 Regal is on it second
    set of plugs at 148k. The first set was changed at 80k.

    If the OP does change them, get equal to the OEM and they should last a long
    time.

    Hmmm, the last "AC-Delco" Iridium plugs I purchased were stamped "NGK"
    on the actual plug. GM has quit making spark plugs itself and
    outsources production of the stuff that goes in those little blue and
    white boxes.

    As far as I know, they are still different plugs.

    Jim,

    Don't believe everything the service manuals tell you. I have a 2001
    3.4 Impala, and my Helms book said the same thing. Ridiculous. You
    have to be careful, but it's not really a problem - I've pulled and
    reinstalled my plugs with no hassle.

    Most of the work will be done by touch - but they should be reachable.
    Be sure to use a real spark plug socket (with the rubber piece inside
    to grip the plug.) And of course, be careful and gentle upon
    reinstallation to avoid stripping of threads - I always start mine by
    hand, with just the socket and extension, before attaching the socket
    wrench.

    It's like on my Colorado p/u - to pull the front spark plug, they (the
    factory manual) say you have to pull a zillion connectors, then
    totally remove the wiring harness. Uh, no. Not necessary. Or my
    old BMW, where they said to change a heater core you had to chisel out
    the steering column mounts. I don't frigging think so (and didn't
    need to.)

    The guys who write these manuals badly need a reality check from their
    mechanics.

    - Larry A.

    I changed the plugs on my wife's Impala around 50k, they are cheap enough
    that replacing them at 50k instead of the recommended 100k isn't that much
    more $. Stick with the AC Delco stuff. I unbolted the coil pack and moved
    it out of the way to make it easier to get the rear and didn't have any
    trouble.
