Exploring the O2 Sensor Range: Comparing Stock Harley vs. Thundermax

When it comes to O2 sensors, one crucial aspect to consider is their range. In this article, we’ll delve into the differences between stock Harley Davidson O2 sensors and the Thundermax counterparts, highlighting their unique features and advantages.

Harley Davidson’s stock O2 sensors are specifically engineered to comply with emission laws, making them narrow bands with a compact 12mm size. These sensors effectively monitor the air-to-fuel ratio to ensure adherence to regulatory standards.

In contrast, Thundermax O2 sensors boast a larger 18mm size, providing a wider range of adjustability.

Whether desiring a richer fuel mixture for increased power or a leaner adjustment for better efficiency, Thundermax sensors offer the flexibility to fine-tune the bike’s performance to personal preferences.

In conclusion, the stock Harley Davidson O2 sensors, with their narrow 12mm size, excel at complying with emission laws.

Unlike other EFI tuning devices, the Cobra Fi2000R Powr Pro sets itself apart by not retaining any fueling information.
