TWIN AIR Pre-filter – Ref. 158028DC
Designed for hostile conditions, this Twin Air pre-filter protects your Beta RR when the track turns into a construction site: dust, sand, and fine mud. It is an airy foam envelope, pre-oiled, designed to reinforce the barrier between ambient air and the original filtering element, thus limiting the entry of abrasive particles into the intake.
This pre-filter is used in conjunction with the original filter to improve the longevity of your intake and limit engine wear due to particles. Check reference 158028DC to ensure compatibility with your model before installation.
