I found 4 brands on the internet for a good price. Which one is the best or are they just about equal. Bosch(83.58), Prenco(80.94), Karlyn(83.50), or Beru(57.38)?

They are OEM and germanautoparts has the set for $99.

Where did you find those?

I've bought some stuff from them already. Arrived in about 3 days. I was happy. :)
