742043 Daytona Twin Tec Fits 2006 2011 Models with Unheated M18 Thr

When you are tuning a Harley for the track or high-performance street use, you often need to bypass the factory O2 sensors to get your air-fuel ratios exactly where they need to be. This Daytona Twin Tec oxygen sensor eliminator kit is designed to plug directly into your stock wiring harness, simulating a cold sensor condition so the ECM stays in open-loop mode. It is a vital piece of kit when using tuners like the Power Commander, Daytona Twin Tuner, or Screamin' Eagle Pro Super Tuner. This set is sold as a kit and fits a wide range of Harley-Davidson models, including Dyna, Softail, Sportster, Touring, Trike, and V-Rod. If you are working on a Euro-5 bike, these can also protect your secondary sensor connectors from dirt and moisture. Just remember you will need software like Diag4Bike to clear any resulting check engine lights.
