    I always had to go under neath to get #8, prior to LT's I think I had to remove the starter to help get some extra space.

    Just did mine Saturday. #8 from the bottom was a snap. Cuts, scrapes, and bruises all over my big hands from the effort, but it's done. New wires too. It had original plugs and wires with 112,500 miles and 9 years old.

    Biggest problem was getting the boots off the old plugs.

    The first time i changed the plugs on my 98 i removed/installed #8 from the bottom... Although It was a major PITA. I have found it way easier to just remove a couple of coils and get at it from the top.

    maybe thats why i think i cant do it from the bottom. its easy from the top for me as long as i take the coils out.

    The only way I can get to 8 is from the bottom...that is without taking anything off from the top.
    Oh and I have LTs

    8 from the bottom was a snap for me. I actually did the wire from underneath too. I'm running stockexhaust and cats too.

    I had to take care to index the ratchet and socket the corret way to be able to turn the ratchet, but other than that is was a breeze.

    I spent more time messing with the coil rail bolts on that side than doing the plugs actually. I ended up leaving them on. Unless you've got forearms like Popeye, you shouldn't have to remove anything other than the AIR fitting on the exhaust manifold.

    [QUOTE=Vince from Shamwow;2655082]Ok, so im going to be changing my spark plugs in my car for the first time myself and i just want to make sure im getting the right plugs and have all the tools ill need. Car is stock

    im going to go with NGK tr55 part number 3951 ( http://www.autozone.com/autozone/par...uestid=5813475 )
    QUOTE]

    With these plugs, they should be gapped at .060 . If you are running boost, you might try .040 . FYI. As you are stock, .060 is what you want.
