Steeda Cold Air Intake Kit

Gain horsepower and torque with this straightforward and easy upgrade. Lifetime filter can be cleaned and re-oiled, but the big news here is that we've streamlined the airflow in the GT 500 Mustang to the point that a computer re-flash isn't just an option, it's required!



The kit is supplied with a stainless steel air box with built-in Billet aluminum Super Velocity stack. It mounts in the factory location with the supplied rubber trim to keep the hot air out. Billet mass air meter is bright nickel plated for a lustrous shine and measures in at an industry leading 114mms!! Our tests showed inlet temps a mere 5 degrees above ambient temperature. The Steeda Lifetime Filter can easily be cleaned and re-oiled, making maintenance a snap. All stainless steel hardware required for installation is included in the kit.
