About S&S Cycle

S&S Cycle has built American V-twin performance parts in Viola, Wisconsin since 1958 — flywheels, carburetors, cams, cylinder heads and complete crate engines. When a Harley owner talks about a 124, a 128 or a 131 build, they are usually talking about S&S. Few names carry more weight with engine builders in this space.

The S&S Cycle Labyrinth Breather Gear Kit is designed for 1999-2017 Harley big twin engines, machined from durable 6061 aluminum. This kit replaces inefficient stock mesh filters with a maintenance-free, sealed unit. The proprietary Labyrinth internal design significantly reduces oil pass-through into the intake manifold.

Why riders pick this

  • Unique Labyrinth design reduces oil carryover
  • Machined from 6061 billet aluminum
  • Anodized S&S blue finish
  • Maintenance-free sealed unit
  • Replaces stock mesh filters on Twin Cam

Stock breather systems can lead to oil carryover into your intake, causing messy build-up and potential performance issues. The S&S Cycle Labyrinth Breather Gear Kit directly addresses this by replacing the factory setup on your 1999-2017 Harley big twin. Its innovative design ensures a cleaner running engine and a more efficient intake system.

Advanced Oil Control and Durability

  • Unique Labyrinth design drastically reduces oil consumption and carryover
  • Constructed from robust 6061 billet aluminum for strength
  • Anodized in S&S blue for a distinctive look and corrosion resistance

A Cleaner Engine for the Long Haul

By preventing excessive oil from entering your intake, this S&S Cycle breather kit contributes to a cleaner combustion process and less carbon build-up. It's a smart upgrade for any Twin Cam rider looking to improve engine longevity and maintain optimal performance without added maintenance. Installation is straightforward for those familiar with engine work, providing a lasting solution to a common V-twin issue.
