Upgrade your engine's breathing system with high-performance Billet Head Breathers from S&S Cycle. Designed to replace restrictive and fragile OEM plastic components, these breathers are engineered from premium 6061 billet aluminum for maximum strength and long-lasting reliability. Whether you are looking to improve engine efficiency or seeking a more durable alternative to stock parts, this kit provides a high-performance solution for your motorcycle.
Our engineering team developed these breathers with a focus on superior sealing and oil management. The dual O-ring design ensures a tight, leak-free seal within the head, while the innovative Labyrinth internal structure significantly reduces oil pass-through. This means a cleaner intake tract, smoother engine operation, and a reduction in emissions by lowering the amount of oil being burned during combustion.
