Halltech TunnelPort is the first step in opening up cold air to your C5. This is legal only in states without a front license plate law, as it replaces the front license plate.
Track only for those states. It is possible to open up more of the fascia area, running this cold air into the Halltech Killer Bee II blade MAF Conversion Package.
