My air filter is a square box with a flat filter exactly like my chevy trucks

Is this normal on a 2009 trooper, I was going to simply put a new fram filter in it and go have fun.

Never mind after reading the forums here I realized the 09's have a box. Funny the manual shows a filter that looks like a k&n

Be careful, the new box still lets dirt through because of sloppy dimensions. Be sure the filter is sealed around the edges.

My 09 had the air box which leaked from the back side. Finally had to put on the old style air intake and snorkeled it up out of the engine compartment, then used a foam Unifilter. Works great, used parts from Home Depot and the auto parts store, less than $50 for the change over. Joyner is aware of the poorly designed air filter on the new machines
