Yesterday I remove the stock air box, filter and hose and replaced them with Mopar Cold Air Kit. Upon removal of the stock air box, the air filter was soaked with oil and there was oil laying in the bottom of the air box. Has anybodu else run into this? I don't think this is how it should be. The duct didn't have any oil in it so I am not sure what to think. Any thoughts about this would be helpful. Thanks.
