Premium Stainless Steel Remote O2 Bungs for Pro Tuner Dyno TuningThese high-quality remote O2 sensor bungs are specifically designed for professional dyno tuning on motorcycles using wideband O2 systems, such as those compatible with the Screamin’ Eagle Pro Street Tuner, Dynojet Power Vision, or similar “Pro Tuner” setups. Unlike permanent welded bungs, these are temporary/remote installations that allow you to add O2 sensor ports to your exhaust pipes without any welding or permanent modifications—perfect for tuning sessions where you want to monitor air/fuel ratios accurately and then revert your bike to its original condition.Crafted from durable 304 stainless steel, these bungs are built to last and will never wear out or corrode, even under high-heat exhaust conditions. They provide a reliable, leak-free threaded port (standard M18 x 1.5mm) for screwing in wideband O2 sensors during dyno runs.The kit includes 10 rivnuts (threaded inserts) and 10 matching screws (often with copper washers for sealing). Installation is straightforward:

• Drill precise holes in your exhaust headers or pipes (typically under heat shields for a clean look).
• Install the stainless steel rivnuts using a rivnut tool for a secure, threaded anchor.
• Screw in the O2 bung or sensor during tuning.
• After the dyno session, remove the sensor and seal the port with the provided screw and washer—leaving no visible alterations when heat shields are reinstalled.

This non-permanent approach is ideal for bikes without factory O2 bungs, leased motorcycles, or riders who prefer reversible mods. It enables precise AFR data collection for optimal fuel mapping, smoother performance, and maximum power gains—all while keeping your exhaust looking stock afterward.A must-have for serious tuners—reliable, reusable, and professional-grade!
