I got the airaid filter and the airaid tube to connect the stock airbox to the intake. My theory is if i want it to work like an airaid box i will leave the top of the stock box off and if i am going off road i will put the cover back on and still have a better filter and a better flowing tube into the engine. The filter and tube can be bought at this web sight for $217.
