    No special tool for the boots, just pulled. I use tune up grease on the boots every time I change plugs/wires though. Makes it much easier the next time around.

    When you guys do plug changes, do you regap? or use factory gap?

    I would gap according to NGK reccomendations assuming you are using their TR55 plug for NA. I use different gaps though since everytime I have swapped plugs on this car was for a different heat range of nitrous plug. I am now on a BR7EF non-projected plug at .032 gap.

    thanks for the heads up, now I know I am glad I took my shop up on the install.

    The oem motor mounts are liquid-filled units with a tendency to fail. When they fail the fluid leaks and leaves visible evidence. Failed motor mounts can cause the motor to shudder a lot at shut down, contribute to driveline clunk and several other symptoms. Even if the oem units get replaced under warranty the replacements can fail too. Aftermarket replacements are therefore, popular. On the other hand, some get a good number of miles on the oems.

    I use the gap that NGK set in TR55IX/TR5IX.

    Nah, no big deal. It's the same as any other V8 spark plug change, just add removing coil packs (4 dual-ended bolts and an electrical connector on each bank).

    Re: Spark plug change = blood on driveway

    Im in the middle of this now too. It took me just over an hour to remove strut bar, coils, plug wires and plugs. Spent nearly 30 minutes of that getting the damn boots off. I had a pickle fork and it was worthless to me. I ended up using a nail pry bar and leveraging against the valve cover.....ONLY BROKE 2 PLUG WIRES!

    Now I guess I'm headed to Autozone/pep boys for some plug wires. I assume I reuse the stock aluminum plug heat shields with the new wires?

    Next is pulling the manifolds off and replacing the motor mounts with the black CS ones. I'm going to paint my valve covers too I think while I've got er all apart.

    I transferred my OEM heat shields to a set of FireCore50 wires -worked just fine.

    nice! i was just wondering that. i took a slice out of one of my wires when doing the plugs yesterday so i've been looking at the FireCores and Moroso Utra 40's. The Moroso's are almost half the cost of the 'Cores and still seem to be good wires.

    I used a garden sheers of all things. Sounds ridiculous but the boot puller was useless, the pickle fork didn't grab the metal sleeve well enough, but the sheers fit perfect. Even had the perfect 30º angle to it. I just needed to be careful....


    ...more careful than i actually was. hence needing to buy new wires now.

    ...also - don't let your neighbors see you if you want to keep your dignity intact. any idea of you being the car guru on your block goes right out the window the moment someone see's you under the hood with a sheers.

    I did not price them everywhere but the GeForce Engineering price on the FireCores is about the same as the Moroso 40's at Jeg's.
