"AIRAID's Classic Air Intakes replace the factory intake tubing and air filter with a low-restriction, high airflow induction system which increases horsepower and acceleration. The addition of a steel intake tube further increases air flow, boosting torque at the drop of the throttle. Every system accommodates the vehicle's factory emissions control devices such as the mass airflow sensor and breather/vacuum hoses where applicable. Most systems come with a choice of an oiled filter or a dry filter as well as your choice of black, red, or blue. Oiled filters are recommended for dusty, dry conditions and dry filters are recommended for daily street driving. Each option is easily washable and reusable and comes with AIRAID's ""No-Hassle"" Limited Lifetime Warranty. Get yours today and let your truck breathe! | Airaid Classic Cold Air Intake 204-104"
