Product Description

The Radium Engineering 20-0909 is a 10AN low-profile press-in swivel fitting designed to replace the removable OEM vent barb on compatible Honda K-Series valve covers. It converts the factory breather port to a 10AN male swivel connection for large-diameter breather lines, making it ideal for air/oil separator and catch can builds on K20 and K24-powered Honda and Acura vehicles. No drilling, welding, or permanent modification is required - the fitting simply presses into the existing valve cover port.

The 360° swivel allows the hose outlet to be directed in any direction after installation, giving builders full flexibility for clean, kink-free catch can routing. Compatibility is determined by engine code, not vehicle model - only K-Series valve covers with a removable press-in barb are compatible. Valve covers with a cast-in-place barb (early K20A, K20A2, K20A3, K24A1, K24A2 2004-2005 etc.) will not accept this fitting.
