that doesn't look like a DX intake.
i have a 00 DX with a short ram intake on (can be extended for CAI) so i can help you if you want... it's fairly self explanatory. take the stock tube and stock air box out and connect it right on the throttle body and put the IAT sensor in the rubber part of the intake and use your hose to connect it from the nipple to the head. the CAI intake that i got made for DX's doesn't need a hole cut. it simply goes in the hole behind the radiator fan and down to the fender well behind the bumper. let me know if you have any questions.
this is what it's supposed to look like (yeah... bay is dirty)
