About these parts
Airaid offers four configurations for the C7, and the difference between them comes down to two choices.
Filter media: oiled media (red or yellow) generally flows more and is cleaned and re-oiled at service intervals; dry media needs no oiling and avoids the risk of over-oiling a filter and contaminating a mass airflow sensor.
With or without tube: systems including an intake tube replace more of the factory path; filter-only systems retain the stock tube at lower cost.
Part numbers 250-274, 251-274, 254-274 and 255-274 cover the combinations across 2014–2018 and 2014–2019 fitments.
