N55 l HP Autowerks, Inc. l Replacement Air Filter l 2011+ 135i 335i

HPA's high performance, high flow OE style air filter replaces the restrictive factory paper filters and lets your engine breathe better. Paper filters do a good job in keeping dirt out but can clogged easily so that they need to be replaced frequently. Foam filters are washable/reusable, allows more airflow.

Simple, 2 minute install time with no tools required.

Average of 3-4 hp and up to 13 ft/lb of torque gain!

Price competively at $64.95
