Why the Killer B?
The Killer B Street Dual Catch Can AOS (SKU: 22BRAOS-D) sets the gold standard for air/oil separation systems.

Whether you’re carving corners on the track or cruising the streets, this system keeps your engine cleaner, enhances longevity, and maintains peak performance—making it the top choice over competitors like Mishimoto, Radium, or IAG.
