Removing air filter from vortech box

Are you talking about this (see picture)? If so, unclamp the dryer hose from the meter and unhook the connector off the meter itself. Then you can pull the Vortech box, filter, MAF, the entire unit from the car. It's a pain because the box is jammed in there pretty good. Once removed you will see how it's assembled. Basically there is a clamp on the inside of the Vortch box holding the MAF in place. Your best bet is buying a power pipe and getting the MAF / Air Filter in the fender for cooler air (see second picture). UPR plastic power pipe, $115 from Rick91GT here on the forums.
