RE: What would void the new Challenger Warranty?
Intake, as in the filter part and up to the throttle body and cat back exhaust. These seem to be fine along with wheel and tire combos. Headers, aluminium, and chrome plated parts for the engine seem to be fine also. Just remember to install the full system if doing more than a cat back. When it comes to heads and cams I believe you are on your own. Super chargers and turbos.... oh yeah your really on your own. I read the Charger forums because they are very similar to how our Challengers will be. Some have tried engine upgrades with varied degrees of success. Seems the computer is a hard nut to crack and fuel mapping is a problem. But the after market is hard at work to open this up to us. I for one would just love a super charged Challenger. And if they break the code I will be one of the first independent (plain ol Joe) to have one.
