Engineered for race-level flow and everyday fitment.
Originally developed for our 130 Bagger GP race engine, the Race Series (RS) BA air cleaner sits just under an inch taller and delivers a 33% increase in filter area over the standard BA unit. The enlarged element and lengthened intake runners increase air velocity and provide a balanced dynamic flow for stronger throttle response and mid-range power. ⚙️
Expect notable horsepower and torque gains on any build, with the greatest improvements on engines running modified or ported cylinder heads, larger intakes, or oversized throttle bodies. The one-piece design creates a clean appearance and simplifies installation compared to stacked, multi-piece constructions.
Set up with OEM-style cylinder head breathing and optimized vent locations, the unit features a high-flow velocity stack with an optimized opening diameter and tapered internal profile. Includes a washable, reusable 3.335" high-flow filter housed in a one-piece cage. Made in the USA. 🇺🇸
