So I baught a K & N and while trying to install it I couldnt get the bottom side of the stock air box off. I think theres like 2 bolts, but there are theese hard rubber retainers. How do I get those to pop loose. Ive tried everything except a pickle fork (haha). Please help me out. Thanks

 

Go down the main forum page to the diesel section and post this on the Power Stroke page, there are guys there who I am sure will help you.

 

Go return that K&N. Get any other filter. They destroy powerstrokes. And post this in the diesel section on how to remove, but just pull hard and the lower housing will come out of them rubber bushings
