Reputable firms will usually substitute bearings in an air-cooled alternator due to warmth They're subjected to. Regretably even Bosch utilizes Chinese bearings which happens to be a pity as the bearing good quality remains not so good as other countries.
Quite popular between the Street Rod established, the 1-wire models are not likely suited to our cars. The only edge may be the simplicity of connecting just one wire.
