    Well, if number eight is on the passenger side very back... You gonna need to get it from the bottom. Just make sure that your car is good and cold or the headers will kill you hand.

    The driver's side one were okay for me but with the passenger side, I struggled so much. #8 I got from the bottom with with a few extensions and the elbow sockets. What was worse was that the plug boot broke off from the wire on #8 and would not come off to save my life. I spend a half hour just getting the plug boot. Good luck. If your girl has small hands, have her help!

    For me its easier to remove the coil packs first. Still very tight but thats how I do it.

    I remove the coilpack, AND the valvecover. Much more room, and actually frees up about 45 minutes.
    Also found a 1.75" extension to be a VERY helpful tool for #8.



    Got my plug changes down to about 45-50 minutes total.

    that's pretty quick. It took me and my buddy at school about 3 hours (with breaks in between, of course). We did remove the egr assembly on the left bank and just worked the right bank, taking turns cause our fingers would cramp up and our backs and legs were struggling to keep us hovering over the car without trying to lean on the fenders too much!

    BTW, anyone know compression spec on the ws6's? i was doing compression testing on the cylinders and was getting 150psi on each cylinder on the drivers side. Didn't mess with the passenger side.

    I remove the little tube that is off of the headers, Air check? (has 2 10mm bolts) Then the last 2 coil coil packs. Use a plug wrench that you can fit a 19 mm socket on the end of. This makes it easier because you wont need an ext on your wrench.My hood is off right now so i did # 8 yesterday in about 20 mins (with taking stuff off and putting back on). BE CAREFUl with the clips on the coil packs, I felt like I was going to break one off...lol
    good luck

    If you go at #8 from the bottom, with a buddy holding the socket in place for you from the top, it is much easier.

    I found that just a 3/8s ratchet and a deep socket worked perfect for getting the #8 plug off from the bottom. I initially tried it with a swivel, but had no luck with it.
