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