I'm going to look at an 88GT donor and I was wondering how you can tell if the car is mass air or speed density? The owner says it is a CA car, so I would assume it is mass air, but is there a visual difference?

If it's a mass air car, the easiest thing is to look for the mass air meter. It should be between the throttle body and air filter. If it's not there, it's speed-density.

Wade is right - if it really is a CA car, you'll see the meter in the intake tube assembly. Otherwise if it's speed density, you'll just have accordian tubing from the throttle body to the airbox, and that's it.

Thanks Guys. I looked at some engine pics on ebay and it's a pretty clear distinction.

Wurf - I believe 88 mustangs originally sold in CA also had Mass Air all other cars went to MA in 89.

Other than the Mass Air Flow meter in the intake tract another thing you can check to verify it is indeed a 88" Califonia car (yes the 88" Ca. cars were MAF)and not a conversion is to check for the three LARGE numbers on the computer...88' MAF cars had 8LD computers,which is in the same family as the A9L.
