      I don't know of any being made today. In the past Granatelli made a larger diameter tube and a custom MAF for our trucks, which is what I'm running. I also have heard of people using 5.0 Stang MAF housings (from the MAF 89-93 models).

      Save your $. Not worth it if you actually find anything. Save that $ into the fix it fund,... because it WILL need it.
      You can throw a cone filter on the end of the MAS with a 3" MAS adapter for about $30. A bigger MAS isn't going to do anything unless you can tune it or in the case of the Granatelli, already be set for the Explorer. The BBK 66mm TB isn't made any longer either...That actually is useful if you can find one. Much better throttle response.

      I don't know the part# sorry. You might be able to contact Granatelli Motorsports about it, even though it's a discontinued item. I'll look at the MAF housing next time I'm in there, but I don't remember seeing anything. They did write the calibration on the MAF sensor itself, but that may not mean anything to anyone but Granatelli and Apten.

      Jason94 is right though, the MAF tube is not a restriction on these engines. The heads are.

      the heads under the valve in the bowl are is extremely restrictive a little work with a grinder and carbide bit and cartridge rolls will solve this. I also think a new bigger maf and throttle body with the porting should help considerably.

      Bigger maf would it be easier if i just snagged a 5.0 mustang maf from that year . Read others threads thats the go to. I already ordered heads from kings cylinders heads.Com heads are swaped when they get here comp cam and bbk 66mm throttle body already on sounds like thats that should all make sufficient power increases
