Review on πŸ”§ Bosch 15703 Oxygen Sensor Replacement: Upstream/Downstream for 2000-2003 Chevy Corvette, Isuzu Express, GMC Sierra, Savana - High-Quality Sensor by Tony Doan

Revainrating 1 out of 5

This is not Bosch

Installed these on my 2000 Chevy Blazer ZR2 after replacing the exhaust and cats. Immediately threw the code for insufficient activity. Apparently this is the wrong part or both are defective.

Pros
  • GOLS Certificate
Cons
  • Protection
