They would use this as an excuse to avoid paying out if they noticed the mods. For extended warranties to stay in effect the car has to be maintained properly and be using OEM parts. If they do not notice do not tell them.

 

Putting back the the stock intake should be no problem. Do you think they will notice 181 pulley?

 

That's what I do ekalks, take off the custom CAI, I want the thing to look bone stock. I leave my Code3 SC pulley on because they are not going to notice anyway. Technically, if the "mod" didn't cause the problem, it should be covered. I like free flow filters but they don't filter as well as those restrictive paper filters. As a lawyer I could make a case that the poor filtering and the increased boost were responsible for the blown engine/seized SC. Etc. The service guys at Chrysler are probably not even going to notice your pulley on most jobs. However, if you blow up your engine or SC, I would put the stock one back on before taking it in for service.

 

The car has 285 width tires in the rear. Will this be considered non "stock"?

 

Well, they are non stock on their face. I'm not even sure they would notice or care. The fact our cars have traction control that you can't "totally" turn off should defeat any argument that they led to a diff/trans problem. Of course I never under estimate the crookedness of insurance companies. I have 285's I haven't put on yet. I sure don't plan on taking them off for dealer visits.
