I pretty much agree with Lil bastard on this one. I installed an Agency Power intake on mine am not sure I gained much. In looking back on it I would think any kit (purchased or home made) without some sort of shield protecting it from the engine heat would be a step backwards (the stock box is sealed and the Agency Power has a shield)? At least with the Agency Power you "open" up the intake air over the snorkled stock box (not sure if this actually adds anything but it helps me sleep better at night).
