SCT BA-2600 MAF
This is the MAF we run on draw-through systems up to about 650rwhp with EEC-IV and EEC-V Fords. (Pretty much any MAF or MAF converted 1987-2004 Ford.)
This MAF is in a 90mm billet housing. If you're looking to attach an air filter directly to it, please note that you'll want an adapter for it.
