ATP GA-11 Cabin Air Filter for Cadillac CTS and SRX

The ATP Parts Premium Line GA-11 is a carbon-activated cabin air filter for select Cadillac CTS, STS, and SRX applications. It helps clean incoming air before it reaches the passenger compartment by trapping fine particles and reducing common outside odors such as diesel fumes.
