Dang, you guys are making me sound like an old hand at working on cars. Changing out the plugs on the Viper was easy as pie. Did not need to remove the air box. Don't see how that would help, honestly (if my memory serves me correctly). Well forward of the work going on for the plugs. For Jaguars, you have to remove the whole intake to get at one bank of the plugs. Viper is clear. Well designed.
Heck, try to change them out on a 89 Firebird V8. Now that requires three extra joints in your arm! The next gen F body, they decided to put in platinum plugs as they were just a royal pain in the butt to do.
Even a novice can do the plugs on the Viper. On a scale of 1 to 10 with 10 being most difficult, this one is a 2.
A battery replacement on the Viper is MUCH more difficult.
