Purchased a 2006 C280 4-Matic on 1/11/08. I have been getting to know the machine a day at a time. I have already figgured outthat the transmission is sealed so I can't check the level myself and understand most of the functions of the accessories(though i'm damned if I can figgure out how to reset/clear the Service II "electronic nanny").

1.Are there any folks out there who make ECM performance chips such as Eric Conforti and Steve Dinan do for BMW's?

2.Which plugs perform better fordaily driving-NGK or Bosch?

3. Any recommendations for ATF and Transfer case oils/fluids when that time comes?

While I am not a neophyte as relates to German cars, this is only my second Benz.

Thanks in advance for any help.
