AEM’s Subaru Legacy GT Cold Air Intake relocates the air filter outside of the engine compartment to deliver the coolest air inlet temperatures possible. A intake heat shield gives you extra protection against engine heat and cooler air carries more oxygen which translates into a more intense explosion in the combustion chamber. These intake systems feature dry flow air filters for the best performance and almost zero maintenance. Every AEM Cold Air induction system is constructed to the highest standards and are guaranteed for the life of your vehicle.
