2013 Cadillac CTS Engine Air Filters

Genuine GM engine air filters for the 2013 Cadillac CTS, at wholesale prices. Factory air filters seal to the housing correctly, which is what keeps unfiltered air out of the intake tract. Second generation Sigma through 2013 and the Alpha based third generation from 2014 to 2019.

When to replace

Reduced throttle response or a mass airflow code after a cheap filter. On a mid-size car, option packages divide this group more than the model year does.
