For the Advanced Evap, you can get NTK (P/N: 25044) or Bosch (P/N: 15630).
For the Bosch, i have found them for $65.99 @ Oreilly: http://www.oreillyauto.com/site/c/d...over&model=Discovery&vi=1377806&keyword=15630
I have also found the NTK @ Summit Racing for $63.69 http://www.summitracing.com/parts/NGK-25044
I know that Advance Auto also carries both the NTK/NGK and Bosch in stock online and a few local stores stock them as well.
