Air Intake Systems

An air intake system is your engine's first breath—upgrading it reduces restriction, smooths airflow, and can improve throttle response and power. Whether you're replacing a tired factory airbox or building a high-flow induction setup, the right intake makes a noticeable difference.

Common configurations include:

  • Cold Air Intakes: Relocate the filter outside the engine bay to draw cooler, denser air—ideal for tuned street and track cars.
  • Short Ram Intakes: Replace the factory airbox with a compact, open-element filter for a more aggressive sound and quicker revving.
  • OE-Style Replacement Filters: Drop-in, high-flow panels that retain the stock airbox while improving filtration and flow.

When choosing a system, consider the filter media (oiled cotton, dry synthetic, or paper), tube material (aluminum, plastic, or carbon fiber), and compatibility with your vehicle's MAF sensor and emissions equipment. Look for systems with heat shields or airboxes to minimize heat soak, and check that all necessary couplers, clamps, and hardware are included.
