How can I tell if my truck has mass air?

 

Would help to know what year this truck is...

Start at the air filter, if you've got hoses
that go directly to the throttle body, with
nothing made of aluminum between, it's a MAP
engine.

Its a 95 f250 w/ 351w

 

Lets see...a '95, well I think its new enough to have a the MAFS in it. If not its not that hard to buy an FIPK from K&N or some other name and while installing that, instal a MAFS too. Pretty much I'd say the easiest way to find out if you have one or not already is to look on your air intake tube, behind your airfilter box, and see if there is wires coming out of a little section near the airfilter box. Other than that, I'm not too sure what else I can say and how to find it and everything. Umm...stock is going to end up looking different from aftermarket so it might be farther up on the tube. I'm not sure. But if you go with an aftermarket one, you'll be getting more air pumped in so its all good. Have a great day.

[updated:LAST EDITED ON 11-Feb-02 AT 08:10 PM (EST)]if you have 2 tubes going from your air filter box to your intake, then you have speed density..
if you have 1 tube with a meter connected to it going from your air filter box to your intake you have mass air (i would assume stock)..
if you have 2 tubes going from your air filter box to a Y branch then 1 out of the Y branch with a meter on it into your intake you have mass air (i would assume aftermarket)...
the meter would probably be connected to the tube at the end that goes into your intake, not at the end coming out of the air filter box.. (but i could be wrong)

good luck
