MASS AIR FLOW KITS.
87-97 Ford 302-351 F-Series Trucks
History
In 1986 Ford Mustangs changed from speed density to mass air because it was more efficient for air flow measuring for driveability. Trucks were not changed over until around 1997 in production. I do not know why it took Ford so long.
Why do I need Mass Air?
Normally, you need mass air for one of two reasons: 1) You changed the camshaft, or 2) a friend told you you needed it because you changed your camshaft. Any other modifications that you make to achieve more horsepower will not be tolerated without mass air. The computer in your truck operates by receiving information about your engine's horsepower (assuming ~ 200 hp) and vacuum that the stock camshaft produces. If the camshaft is more than 205-207 degrees duration @ .050, your truck's engine performance will suffer greatly. Mass air will allow you to make performance-enhancing modifications to your truck, and perform properly. The stock injectors are 19# and they are matched with the air meter that comes in the mass air kit. At about 270 hp you will need a 24# set of injectors and a 24# air meter upgrade. At 325-350 hp, you will need a 30# set of injectors with a 30# air meter upgrade. At 400-425 hp, you will need 36# injectors and a 36# air meter upgrade. At 500-550 hp you will need 42# injectors and a 42# air meter upgrade. If you are making any more modifications than above, please call.

What problems might I encounter
If you elect to install mass air kit yourself and are not a certified mechanic ( and many people do) and you do not have any trouble you win. If you do have problems you will need the Ford manual troubleshooting guide only available from Ford Motor Co.
"ENGINE|EMISSIONS-DIAGNOSIS I989 SHOP MANUAL" VOLUME H CAR | TRUCK AND YOU SHOULD HAVE A BREAKOUT BOX. These tools are available to buy or rent from E-Bay. The computer is from a 1989-1993 Mustang. The manual has all diagnostic procedures and tools needed to solve any problem.
It will list all computer codes and what they mean. Mass air will not fix existing mechanical problems. Please do not expect us to fix for you. We have sold these mass air kits for years with minimal problems. When you do not know what is wrong everyone looks at the computer. Rarely is the computer the problem. But our computers are guaranteed. They are very expensive. If you do suspect a computer problem we will have you ship it to the builder for inspection. If they find a problem they will fix or replace it. If not they will return it to you. You will have to find your problem. If in the process of installation it was burned up you will have to purchase another one. They are not repairable if burned up. We must trust our builder.
Do you sell mass air parts alone
Yes any of the components in the mass air kit can be purchased alone (pending availability) The wiring harness is the most popular part to purchase alone. The 302 harness and the 351W-HO harness are available at this time. The 302 for $195 and the HO for $295
