It all to do with a situation with the clearance on the under hood bracing that could come in conflict with the air cleaner lid. The problem was solved in typical MOPAR fashion. With a BFH or cutting torch, everything can be made to fit! The issue was that the engine torqued up and would pinch the air cleaner up against the hood bracing and that would interfere with the throttle linkage and the throttle could be locked open. It didn't happen all the time but the time that it did, the fix was to cut the under braces out of the hood.
But as anyone that knows anything about the MW cars, the only day that they were original was the day that the buyer picked the car up at the selling dealer. After that, it was game on. First thing that needed to be done was to get rid of those big o' cast iron headers. And then cut out the fender wheels. And throw those air cleaners away. And while were doing that, lets port out the intake. And the story goes on and on and on.
