Updated Breather Assembly for Briggs Raptor Engines - Supersedes 555073

Breath easy—your engine does with the breather assembly (SKU 555689), an upgrade over 555073 for Raptor flatheads. It routes excess vapors away, balancing internal pressures to keep oil where it belongs: lubricating, not flooding.

• Integrated reed valve design filters contaminants for purer recirculation.
• Compact housing mounts unobtrusively, preserving chassis clearance.
• Enhances vacuum efficiency, aiding overall airflow for better throttle mapping.

Without proper venting, crankcase gunk builds, starving your piston of clean lube and dulling response. This assembly counters that, sustaining high-vacuum pulls that sharpen acceleration. Racers notice crisper idling and less smoke, signs of a healthy breather at work.

Ideal for frequent oil changes in pit lanes, it simplifies maintenance while bolstering longevity. Superseded for refined performance, it's a must for tuned setups chasing every RPM.
