Injen X-1081 Replacement Air Filter – SP1116 Intake (BMW S55 M2 Comp / M3 / M4)

OVERVIEW

The Injen X-1081 is the replacement air filter for the Injen SP1116 intake. Fit it at service time to restore the airflow and filtration of the original element — this intake uses two filters, one per side.

The X-1081-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.
