Just got an '04 330CI SMG etc. Is it bad to put a GruppeM intake on immediately?
Should I keep the stock intake for the first 1000 miles or so or is it better to get an intake immediately so the car can breath better during break in? Im keeping her under 4K rpm till 1500miles or so and then I will gradually bring the revs up.
I got the 330CI Sport/SMG/Prem/Navi/18"/Zenons/Brushed Alum. Great car, will have pics up this week Im coming from an Audi so the interior is not as great, but the car has a soul unlike the Audi
