Product Description

For the largest possible performance gain replace the entire air box and intake tract with the aFe Stage 2 Open Element Air Intake System.


  • No Floating Tubes – Built-in ram scoop forces cold air to filter for greater efficiency and performance gains.
  • Clamp Stops – Raised stops on aFe tubes provide a more secure seal and eliminate slippage versus flat, straight tubes.
  • 3-Angle Adapter – Specially developed velocity stack with 3 different angles dramatically increase airflow from the filter to the intake tube.
  • Quality Hardware – aFe uses only top-quality hardware like stainless steel button head bolts and brass inserts.
  • 3 Filter Media Choices – Choose from the Pro 5R, Pro Dry S or Pro-GUARD 7 Filter.
