Slot Style MAF Flange, Stainless Steel, 3" Pipe

Stainless steel weld-on MAF flange for slot style MAF. In 2005 Ford introduced a new style of mass air sensor called the "slot" or "card" style. This sensor has no housing, instead the stock air box has a receptacle for the sensor. The stainless steel MAF flange provides a housing for aftermarket slot/card style sensors. With a 3.0" circumference, the flange can be attached to other tube sizes with some welding.
