Wide range of sensors

Bought for my '99 Suburban as both sensors had heater issues. The sensors are of good quality and work as expected. A few months no problem

Wrong connector 1999 5.7 Vortec

Electrical connector wrong for 1999 K2500 5.7 Vortec. Waste of time screwing it up to find out he can't connect to the truck.

Pros
  • Price
Cons
  • old

You did not receive the advertised brand.

Product advertised as Bosch; However, I got a generic unknown brand. Since my car was in the middle of changing parts, I used the parts that came with it.

Pros
  • High test scores for support and durability
Cons
  • Other Other

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

DOES NOT FIT THE BOTTOM CONNECTION!

As other reviews have mentioned, this is not Bosch - tricky wording - a Bosch replacement. Furthermore, they are suitable for both upstream and downstream positions, at least on Sierra/Silverados. The input has a rectangular/oval connector and the output has a square connector. They are for upstream only.

Pros
  • Handsfree
Cons
  • Legacy model
