Hey I'm at work on friends sidekick so I can't use the search. Anyways I just bought a deckplate and dremel before work and I go to school right after were I plan to do the deck plate mod (I have auto collision class) anyways. I wanna make sure I'm doing this right. I take off the airbox cover. The side facing the core support-headlight I cut a 4" hole. Then screw in the deckplate and that's all? Seems realy easy wanna make sure not more is involved. Also do I need to change my filter? Mine is new from recient oil change but if there's one I should use which one? Thanks for the help!
