SD or MAF??

Ok, I'm going to get this straight once and for all. Do I have Speed Density, or MAF.


Air Box w/filter -----sensor-----one round tube----splits into two tubes, then hooks to throttle body.


Thanx for the help.

You have mass air. If you had speed density, you would have two seperate hoses from the air box all the way to the throttle body and no sensor in the hoses.

MAF is a little better in accepting mods like a cam/heads/intake and the like. I think they get a touch better mileage or emissions because they were used on CALI emissions 1995 4.9L and 5.8L trucks and all 95 5.0 automatics. SD is a decent system I think, I wouldn't change it costs 700 or so to change and is kind of difficult. Unless you plan on some super mods stay with what you have. The SD is tunable too, they have some SD friendly cams out there and with a chip it can take most head/intake mods. You can put a supercharger on a SD truck and be fine too. But unless your doing some large mods (the heads, intake etc.) you can do just fine with what you have.


Primary rig is Green Thunder:
95' F-150 XLT 4x4, 302, 5 spd, MSD 6A, Flowmaster Exhaust, Sunroof, Clear corners w/ Diamond headlights, CD player with 2 10" subs and some 32" BFG Muds .

Small correction on MustangGT's...I'm not sure what the deal on the 95 5.0 is with s/d and maf because I know a few guy's with 95 5.0's with S/D and some with MAF...all with different variation's on the tranny to some have auto with s/d some have manual with s/d and same with MAF...I'm wondering if maybe the switched to MAF on the 5.0 like in 95 1/2?

That could be true because I know mine was made in April of 95. SO anything is possible.
