We had this gorgeous Laguna Seca Blue E46 M3 SMG in for our Carbon Airbox and Alpha-N remap, which provides a 25-30hp gain, along with an unrivalled induction sound.
It was a lovely example of what is becoming an uncommon car to see in our workshop, but we used to be inundated with them 5-10 years ago. The S54 engine is one of BMW's greats, and the looks are just classic BMW M car.
