After searching for a large capacity, proper "Vortex" style catch can for years, we finally made our own to our specifications for MkIV Volkswagen applications.
Vortex design means incoming gasses hit round cylinder wall being forces to spin in a "vortex", centrifugal force causes oil and water particles to fling outward and drain down the walls to be collected or returned to the sump.
This breather can is recommended for all high performance applications to remove oil vapor from the intake tract.
Sold in a black powdercoated finish.
Note: Pair with 1" Breather Filter to easily expel gasses out of can.
