Worthless Automotive Oxygen Sensor

The Denso oxygen sensor was a complete waste of money. As my tests showed, it failed to accurately measure oxygen levels in my car's exhaust and caused my check engine light to constantly be on. While the price was reasonable, the product's performance was severely lacking.

Pros
  • Affordable
Cons
  • Inaccurate readings, caused check engine light to constantly be on.

Great item and made with quality materials.

This was exactly the part I needed for my 1990 Subaru Legacy (257,000 miles). Great item and made with quality materials. Now my car runs better and quieter.

Pros
  • Sensors
Cons
  • Hard to say

Quality product and delivery on time

Item received in good condition but delivery was delayed. The wires of different colors (blue/black/white) on the product make installation difficult. There were no plugs in the kit, these had to be soldered. I will not buy again

Pros
  • Oxygen
Cons
  • Vulgarity
