AKRAPOVIC 18mm x 1.5 Lambda Sensor Plug P-LBSB1

If you're running a custom exhaust system or tuning your engine for a specific configuration, you'll need a proper solution to seal the O2 sensor port—and that's where this Akrapovic lambda sensor plug comes in. Rather than leaving the port open (which causes air leaks, check engine lights, and tuning headaches), this CNC-machined billet plug provides a clean, permanent seal. It's the OEM-quality solution that serious tuners and racers rely on to maintain exhaust integrity and engine management stability.
