People then say that anything Bosch sucks, when in reality most of what they make or sell is top quality.
Their brand 100% new (said that on the box) water pump lasted a whole 11,000 miles on my LT1, before it started weeping. Stock pump went 140K

Two year old reman from Pepboys (where bosch was from- someone put wrong unit in bosch box when I went to get new one, so I just returned it as I needed the pump in a hurry) was fine when I pulled it off.
Many many people who put bosch 02s in their LT1s end up throwing codes, having it run horrible, etc. Put OEM sensors back in, and it works just fine.
Just like any product some can be hit or miss. I tend to stay away from Bosch if I can
Perhaps it's a Bosch/GM compatibility thing
Given their relationship with Ford, hehe
