K&N 33-3042 Replacement Air Filter
Upgrade your BMW diesel with the K&N 33-3042 replacement panel air filter. This high flow, washable and reusable K&N air filter is a direct OEM replacement for the standard paper element, designed to improve airflow, support performance and throttle response, and deliver long service life. Perfect for daily drivers and performance enthusiasts, the 33-3042 drops straight into the factory airbox for a quick, easy fit with no tuning required.
At Nforcd we run these filters on our own cars and customer vehicles, and the feedback has been consistently positive. Sharper response, a subtle induction sound and the convenience of a serviceable filter that can be cleaned and re-used again and again.
