How to Install A Cold Air Kit

Lots of fresh air is good for both people and cars. Getting more fresh air for yourself might involve less TV and more outdoor exercise, but getting more fresh air for your Mustang is much easier.

An engine is a giant air/fuel pump so the more air you can pump through it, the more horsepower it will produce. Factory air cleaners and air intakes are somewhat restricted for a variety of reasons including noise. Performance people don’t mind the sound of more air as long as it means more power and better fuel economy.

The amount of increased air volume can vary depending on the brand and design of the cold air kit. The higher flowing units such as the one in these photos require that the car’s computer be re-flashed. Smaller flowing kits can often be used without any computer adjustments. You should check into this before purchasing a cold air kit.

Re-flashing your computer can add substantially to the total cost of the cold air kit. A kit that requires re-flashing will give better results, but you need to buy a special reprogramming tool. The tool is matched to you car’s VIN so it can only be used on the car it’s registered to. You can do lots of valuable tuning and diagnostic procedures with the re-flashing programmer, but it is an added expense. The programmer can also do things such as adjust your speedometer if you change tire diameters.

A cold air kit will improve any Mustang. They’re most popular with the V-8 crowd, but V-6 cars can see very noticeable gains, too. Depending on the kit and manufacturer a late-model Mustang V-6 can expect a 20-25 hp gain and a V-8 can expect an additional 25-30 with a cold air kit and reprogramming.

Russell Williams at Tulsa Car FX demonstrated what it takes to install a cold air kit in a 2005 or newer V-6 Mustang. The procedure is similar for V-8 Mustangs.
