Product Description

If you want to maintain a factory appearance the aFe Stage 2 Si Sealed Air Box provides quiet performance and industry-leading power gains.


  • Ram Air Scoop – 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.
  • MAF Sensor Pad – Precision tuned MAF Sensor Pad will not affect vehicle performance or produce check engine light warnings.
  • 3 Filter Media Choices – Choose from the Pro 5R, Pro Dry S or Pro-GUARD 7 Filter.
