Beware of Counterfeits
The market is flooded with counterfeit Bosch 4.9 sensors, making it increasingly difficult to distinguish genuine parts from fakes. One key indicator is price: if you find a 17025 sensor priced even $10 lower than ours, there's a high likelihood it's not genuine. We maintain some of the lowest prices in the country because of our bulk purchasing power, thanks to our integration with Spartan wideband kits. Most competitors sell these sensors for at least $30 more, so treat any significantly lower prices with caution.
