6. Injen Technology submits all of our air intake systems for CARB exemption approval (California Air Resource Board). All of our air intake systems are either certified by CARB or have been submitted for CARB exemption. Considering California has some of the toughest emission laws in the country, CARB approval has been accepted as legal by other states. Each of these kits includes a high temperature decal with the CARB exempt OEO number. This decal identifies approved aftermarket add on products from non-approved products. As long as you have the approved decal you shouldn't have any problems with vehicle inspections. You can visit our Website www.injen.com and click on CARB EO listings to determine the CARB status.
