Anybody with a euro vehicle and doing his/her own maintenance has had interaction with Bosch replacement parts. In my opinion most of the parts Bosch makes are very good and unusually reliable. I've used their filters, ignition parts, brake pads and electronic relays. They mostly cost more but are worth the additional money. No failures ever but I quit using their spark plugs years ago. Denso and NGK are what I use now. BTW, I think most Denso replacement parts are at least as good as Bosch. I've never had such really satisfying experiences with domestic replacement parts.
