Key Features

• Reusable, cleanable cotton filter media
• Pre-oiled for filtration and airflow

• Red and black color options

Dyno Test Context

VTT’s shop M3 averaged 726.67 WHP across three factory-lid/filter runs and 739.93 WHP across three runs using VTT carbon lids and these filters. The 13.26 WHP average delta applies to that combined lid-and-filter test on that vehicle; individual results vary.
