The reason for the boot and my Ravelco security system is that my son's customized Honda Civic was stolen in front of my house five years ago. The cops found it stripped in Camden, NJ one week later. It was a total loss and my son was heart broken. So, no one is going to get my Challenger!
And make sure that you have a good torque wrench. You definitely don't want to over-tighten! For the 5.7's .... Most of the Gen II Hemi's came with Champion plugs. I know my wife's '07 Charger did. The Gen III Hemi's come with NGK plugs. There's no need to change from the basic copper plug unless you have mods and have changed the tune. In that case, take the advice of your engine builder --- not my advice or anyone else on any message board.
Yeah, because sometimes they're wrong Three different generations of Hemi engines have been built by Chrysler for automobiles: the first generation (known as the Chrysler FirePower engine) from 1951 to 1958, the second generation from 1964 to 1971 which included the infamous 426, and the third generation beginning in 2003 Therefore the second generation information in your post is wrong, sorry.
