This is a new OEM seal on the underside of the factory airbox assembly. It seals with the Mass Air Flow (MAF) housing at the back of the engine. If yours is torn, damaged or missing; we have the replacement!
This is to be used with the OEM airbox assembly and OEM MAF housing. If you have one of our Cold Air Intake Kits this seal will not be needed as we eliminate that connection with our kit.
