No do not cut your airbox. Number one there isnt a cone that I have seen that is big enough because the mass airflow sensor sets too close to the air box for a cone filter to fit.. I have an 05 2.2 with a k&n short ram typhon and a 2.4 intake manifold conversion from crate engine depot.com and i am now running about 152hp from the stock 130hp to the wheels.. If you try to make your own intake it wont run right because the throttle sensor opens and closes at rates that all depend on the info sent from the MAS.. the k&n runs about $230
