I normally stick with Bosch & NGK Plugs, but members on this forum have used plugs from Beru and other vendors with excellent results. Don't forget guys that vendors will occasionally update their part numbers..
Most manuals will reference NGK Part Number: BKR6EKUB as OEM, but these plugs have been replaced by Part Number: BKR5EKUP. The NGK plugs require .028 gapping!
Bosch Part Number: F7LTCR are also listed as OEM for our Passats and they have been replaced by FGR7DQE0. These plugs require no gapping! The Platinum +2 and Platinum +4's should also work well.. Plasticar, let us know how your plugs hold up over time!
Good luck...
