The second edition of the RS4 came in the B7 trim and was almost completely different than its little brother, the S4. A hearty 414bhp from the completely redesigned and high-revving V8 developed by Audi Sport sat under the hood and propelled the B7 RS4 like a rocketship. Only 10,000 were produced worldwide and only 2,000 examples made their way to the states, making these cars worshiped and sought after to this day. Everything from widened arches, unique Recaro seats, the Getrag manual transmission, to the cast magnesium intake manifold makes the RS4 special in the Audi lineup. If you are one of the lucky few to have one, you can find everything you need to keep it pristine or make it your own right here at ECS Tuning.
