Gotta disagree with you there too. I've had a Bosch O2 sensor in my bonny now for almost 3 years / 62,000 miles and its been great. Then again my opinion on this is biased as well, since my dad works for Bosch. 27 years and goin.
I'm not gonna stick up for their plugs in our 3800'* though, they dont seem to do to well at all in them, especially the +4'*.
In Bosch'* defense however, I wouldnt totally count out their products. Take a look at NASCAR and INDY. Its something like 26 out of 30 NASCAR race teams are now on BOSCH spark plugs, and every single Indy car is running them with the exception of 1 or 2. These numbers are growing and growing too, this year alone Bosch picked up Jeff Gordon along with the rest of Hendrick'* teams / drivers, as well as a few others. Mercedes, BMW, Audi, Porsche, I'm pretty sure all come factory with Bosch plugs in them now. Obviously they are doing SOMETHING right, but just because for some reason they dont seem to do well in 3800'* isnt enough for me to "NEVER" by anything from them. Their power tools are also some of the best on the market (and Bosch just bought out Skill), so once again, the company must be doing something right.
Sorry Willwren, I'm not trying to start problems or anything like that, just stating my opinion. Ok, its probably very biased since Bosch is like family, but it just means alot to me I guess. Just FYI for everyone too, Bosch celebrates thier 100th anniversary this year, and they are STILL privately owned (not publically on the stock market). They are a multi-billion dollar company, and still pay cash for everything! They bought out Skill power tools (1+ million something) in cash! If you've every been to Germany, Bosch is like the GE of America. They're not just automotive, they make home appliances (dishwashers, stoves, refridgerators, etc..), power tools, industrail products, lights, etc.. etc.. They are also VERY highly recognized for having some of the best quality in the industry. Go to Http://www.sears.com
and look at dishwasers. You'll notice that the Boschs are some of the most expensive / highest quality they sell. Get what you pay for, just remember that.
Anyways, sorry for such a long post, just had to get my point across
