I'm giving a 5 star because the product worked pretty well even though it's 60% less expensive than similar parts at Auto zone or O'Reilly's. Initially when I installed this converter, my car failed the catalytic test and later I found out it was because I didn't weld the converter to the exhaust, I used a clamp instead. Then I decided to use patching products and cement or glue for exhaust connections. (you can buy it at auto parts store.). After that everything worked well.

I've always used Bosch O2 sensors on my vehicles & they are of good quality,dependable & get the job done.Bosch even puts some anti-seize on the O2 sensor threads making them easy to remove the next time & saves me from having to buy a tube that will just sit there.Good job Bosch.

Did not see Bosch symbol on it and numbers stamped in the metal did not produce and google information but it is as the same OEM quality if not slightly better. OEM did have a wire protector and the Bosch bulk O2 sensor did not. Hey local retail is $69 plus tax. This one was less than half and worked perfectly. The world needs better deals locally instead of on the web.

I was worried about the catalytic converters being clogged or deteriorated. Not the case. Original ones still installed. 230,000 miles. No codes in a week of driving. Check yours for being loose before you buy. I did find one that wasn't completely tight. But, the gas mileage went up considerably and it runs a lot smoother.

Not sure if these are truly Bosch or not as they come in an unmarked box. I replaced Bosch o2 sensors that were in the car with these. They looked the same but the old ones said Bosch on the sensor. I guess as long as they work. Price was best around.
