Sensor Bung Plugs

2 products

Our range of Sensor Bung Plugs for Harley-Davidson covers the threaded plugs used to seal unused O2 sensor bungs in stock and aftermarket Harley-Davidson exhaust systems on 2009-2025 Sportster, Softail, Dyna and FLT/Touring models with 12mm sensor ports, and 1986-2006 Big Twin and Sportster models with earlier O2 bung formats. Iron City Motorcycles in Leeds is an authorised Harley-Davidson dealer, and sensor bung plugs are a small but important part of any custom exhaust fit where the new system has unused factory sensor bungs that need weatherproof sealing on a Harley-Davidson. You will find MCS's workshop-standard sensor plugs and Vance & Hines's precision-engineered sealing plugs, matching the thread pitches and sealing faces used across modern Harley-Davidson exhaust systems. Whether you are finishing a custom 2-into-1 install, sealing spare bungs on a tuning setup or neatening a factory exhaust swap, the correct plug is here. Browse the full range below.
