Introducing the PMAS LMAF. This is our low cost Lightning maf replacement. We have eliminated the four bolt flange so adding a filter is a snap. As with all PMAS mafs, this unit uses the newer more accurate slot style sensor. We offer this maf with the O.E.M. standard lightning maf curve (450WHP) as well as 2600 (650WHP) and 3000 KG/HR (750WHP) curves for added horsepower!
