-10% WBO2 Sensor, Sniper TBI & Terminator X

Note that this is a different sensor than Holley uses for their Dominator/HP/Terminator/Avenger series. But you've found the right one for your Holley Sniper EFI System OR your Terminator X EFI System.

Why Did My Wideband Sensor Fail?

According to AEM Electronics, a leading manufacturer of aftermarket Wideband O2 sensor kits, the following may damage or destroy oxygen sensors:

  • Leaded (tetraethyl) fuel
  • Silicone
  • Oil
  • Engine coolants
  • Particulates, carbon (e.g. excessively rich mixtures)
  • Mechanical shock (e.g. dropping a sensor on the ground)
  • Thermal shock (e.g. blown head gasket)
  • Extreme exhaust temperatures (Greater than 930 degC/1700 degF)
  • Unheated sensor in exhaust stream. Sensors that are installed in an exhaust must be connected to a properly functioning controller during engine operation

Additionally, if an Sniper or Terminator X EFI System has repeated O2 sensor failures and none of the above-listed suggestions seem likely then contact Holley and arrange to have the unit tested. It is possible for the ECU to have an internal failure that can kill O2 sensors. While this is extremely unlikely if you are having immediate, back-to-back O2 sensor failures you should make the effort to rule this out.

What Is The Difference Between The Holley and Bosch Sensor Options?

As far as a sensor goes, absolutely nothing. 100% identical. As far as packaging goes, one comes in a Bosch box, the other in a Holley package. As far as warranty goes, Holley products are covered by a 90-day warranty against defect in material or workmanship. The ones in the Bosch box come without warranty.
