Wonder how different the air box specs are between the 3.5 and 3.6? I would imagine its total diff shape and location. I know the 3.5 is a 2 piece. I just removed outer section that runs from box to top of grille and noticed a diff in mpg and a little more torque from take off. Not bad for just removing something.... and yes I have also read that avenger Cai will work on the journey. Another mod I did ( first mod) was drilled and spotted brake rotors. Huge huge difference in stopping power. Best and favorite mod yet. All 4 rotors and ceramic pads for 230.00 off ebay.
