Injen X-1105 Replacement Air Filter – SP1123 / EVO1103 Intakes (BMW N20 / B46 / B48)

OVERVIEW

The Injen X-1105 is the replacement air filter for the Injen SP1123 and EVO1103 intakes. Fit it at service time to restore the airflow and filtration of the original element.

The X-1105-BB uses Injen's SuperNano-Web dry synthetic media — no oil and no risk of oil migrating onto a hot-film MAF sensor. Wash it in warm water, let it dry and refit it.
