Toyota Cold Air Intake

Aftermarket cold air intake systems come in many different colors and sizes, and are easy to install when compared with other performance-increasing modifications. All cold air intakes operate on the principle of increasing the amount of oxygen available for combustion with fuel. Because cooler air has a higher density (greater mass per unit volume), cold air intakes generally work by introducing cooler air from outside the hot engine bay.

  • increasing the diameter of the air intake, allowing increased airflow.
  • smoothing the interior of the intake to reduce air resistance.
  • providing a more direct route to the air intake.
  • tuning the length of the intake to provide maximum airflow at certain engine speeds (RPM).
  • using a more efficient, less restricting air filter.
