The Akrapovic O2 Sensor Port Plug is designed to seal an unused oxygen sensor opening in compatible exhaust systems. This plug is intended for applications where an O2 sensor is not required, helping close the exhaust sensor port and maintain a finished, properly sealed installation. The 18 mm x 1.5 thread specification supports fitment with compatible Akrapovic exhaust components and other systems using the same port size. Always verify the exhaust system specifications and vehicle application before installation.
The Akrapovic P-LBSB1 plug is supplied as one individual piece and is suitable for replacement, conversion, or custom exhaust installation needs. It provides a practical solution when an exhaust configuration does not use an oxygen sensor, preventing the open sensor port from being left exposed. Proper fitment depends on matching the plug thread to the port in the exhaust system, along with confirming that the vehicle or application does not require an operational O2 sensor for proper engine management or emissions compliance.
Manufactured by Akrapovic, this O2 Sensor Port Plug combines application-specific design with the brand’s focus on high-performance exhaust accessories. The manufacturer part number and vendor part number are both P-LBSB1. This product fits compatible exhaust systems requiring an 18 mm x 1.5 O2 sensor port plug and is intended for use by qualified installers or experienced mechanics. Follow the exhaust manufacturer’s installation guidance, use suitable tools, and ensure the plug is securely installed before operating the vehicle.
