Fits 2007–2026 Honda Rancher 420, Foreman 500/520, and Rubicon 520. Keeps your ATV running clean when it's underwater. Without an O2 delete, your ECU reads a lean condition the mom ent water hits the sensor and cuts power or shuts down entirely. This sensor tricks the system into holding a proper air/fuel mixture regardless of what the stock O2 sensor would otherwise report — a required piece if you're building toward real water crossings.
