Bosch Spark plug
Stormgrey93
Rating 4.5
  • Acceleration:

Now running the Bosch +2 Platinums and my MPG jumped from about 21 to 25! A lot of others will tell you not to mess w/ the platinums but they are doing well for me.

Pros: improved MPG

Bosch Alternator pulley

A Bosch alternator doesn't care which Bosch pulley it uses, be it a 70A, 90A, 120A or 150A. The shaft is the same 17mm OD for all of them. What matters is that the pulley matches your belt and application.

Pros: pulley matches belt
Vehicle: Volkswagen
Part number: 021 903 119 D

Bosch Glow plug
8v-of-fury
Rating 4.5
  • Cold start:

From what I understand the afterglow on the Duraterms works because they self regulate voltage per each plug, not allowing them to burn out. It virtually eliminated rough idle on the cold start.

Pros: virtually eliminated rough idle
Vehicle: Volkswagen Jetta

Bosch Glow plug
8v-of-fury
Rating 4.0
  • Cold start:

I have installed these in my 81 and they work very well. Start it up and let the plugs sit on for an additional 30-45 seconds.. pretty much does away with the rough cold starts.

Pros: work very well
Cons: rough cold starts
Vehicle: Volkswagen Jetta

  • Electrical behavior:

OK. First thing is the voltage regulator was faulty. It was a new voltage regulator but it wasn't a Bosch part. I switched the 2 regulators and the problem went away.

Pros: problem went away
Cons: voltage regulator was faulty
