Air Cleaner/Intake

     A hi-flow air cleaner will allow more air to get into your system. Depending on how radical you want your DSM to look, you can get a stock replacement that will fit in the normal airbox, or some people use the cone filters that completely get rid of the airbox and hang out in free air. A K&N Filtercharger kit for the 3000GT will also work with just a modification to one or both of the brackets that mounts it to the car.

     Note - Where the air box connects to the MAS is an aluminum honeycomb air straightener. You may be tempted to remove this material in order to improve air flow. If you do, be prepared for occasional rough idle and stalling. The "Check Engine" light may also be permanently lit requiring you to disconnect the battery to reset it. A few members with "daily drivers", including myself have tried this mod but decided to put the honeycomb back on because of the drivability issue.

     Another Note - It has been reported that the rubber hose that connects the exhaust side of the blow off valve extends well into the air intake hose (right behind the MAS). A member has mentioned that this hose blocks off about 75% of the air flow coming in from the MAS! Cutting of this hose inside of the air intake hose has been successfully done by members and is advised to improve air intake.

     WARNING: This hose can NOT be removed and the hole capped. If you have any intention of driving your car anywhere other than the drag strip you don't want to vent your BOV to the atmosphere. As many members have pointed out to me, the air you are venting has been "counted" by the MAS and the ECU expects it to be there. Serious drivability problems will be encountered should you vent your BOV to the atmosphere regardless of whether or not you remove the return tube. A VPC will allow you to vent to atmosphere (it senses air flow at the throttle body not before the compressor) but we aren't there yet in our mods so just hold your horses :) Get it . . . I said "Horses". Hey you better laugh or I'll send RUF after you.

Hey you NT guys out there. Don't feel left out. This mod is a good one for you as well. You can gain something like 5-10 HP with good cone type filter.
