A cold air intake will deliver cold air in a quick effective method that will give your engine more of an air fuel to ratio. When more air is delivered to your engine, the horsepower will increase as well as acceleration and the torque. You can make your own cold air intake using basic supplies you can get at hardware store.

  • 90 degree rubber elbow (3 inches in length)

  1. 1

    Use a wrench to loosen the negative cable of your vehicle battery. This needs to be done before attempting any work on your vehicle.

  2. 2

    Use a flathead screwdriver to loosen the metal clamps on the air hoses of your air intake. There will be a hose connected to the throttle boy of your engine as well as hoses leading to the air box. Remove the clasps from the air box and unlatch them so that you can take the air box out. Remove any remaining air intake tubes. Set all of the air intake aside beside the MAF sensor and the 45-degree elbow.

  3. 3

    Connect the MAF sensor to the 45-degree elbow. Connect the MAF sensor onto the 45-degree elbow using the metal clamp. Tighten the clamp using a flathead screwdriver.

  4. 4

    Connect the 90-degree elbow of your intake to the throttle body and tighten the metal clamp ring using a flathead screwdriver.

  5. 5

    Position the pipes so that you know the appropriate length to cut the muffler pipe to. Cut the muffler pipe using a metal cutting tool. Insert the muffler pipe in between the other connectors and tighten the metal clamps to tighten it into place.

Tips and warnings

  • Make sure that the MAF sensor is facing the right direction when you are connecting it.
