I replaced all spark plugs with Genuine Audi NGK plugs and replaced all Ignition Coils as well.

Within the last 8,000 miles New spark plugs

The part number I have for the Bosch is 4418. There web sire below only goes up to 2000 EV so I don't know if these are the same as the 2001 + EV. I really love these plugs and ran them in my prior Audi A6. Long lasting, great even spark, no gaping. Bosch claims (see web site) increase power. Maybe?
