K&N's Typhoon Intake System comes with a high-flow air filter, MAF adapter, intake tube, and cold-air extension. Together they create a radius entry smoothing and straightening the airflow. This allows for a greater amount of air to be ingested versus the factory air box.
Since this filter is washable and re-usable, it could outlast the vehicle it's installed on!
K&N claims gains up to 9.5 hp!!!
