S&B Cold Air Intakes increase cool airflow to your engine while still protecting it from harmful dirt and debris. More airflow has been shown to increase horsepower. S&B Cold Air Intake Kits minimize airflow restrictions while maintaining high filtration (efficiency) ratings to protect your engine.

All S&B Cold Air Intake Kits released after October 2013 are made with silicone rubber instead of standard urethane rubber used by most competitors. Unlike urethane, silicone won't crack or tear with extended use.
