Which Spark Plugs?

Due to poor gas mileage I am going to try replacing the plugs and possibly the intake boot. If anyone has had their plugs replaced lately by a dealer, which plugs did they use. Realoem.com shows all plugs discontinued and does not show a replacement which is rather odd.

Many recommend the NGK spark plugs...or Bosch, compared to OEM. Just changed out our OEM plugs and used NGK laser platinum for our X3 2.5. They (NGK's) were about $8 bucks a piece...I think the OEM are like $15-20 a piece.
