Heard it's purely a cosmetic & sound mod & does not/ or has very minimal performance gain (ie >2-5).. 3400 siap pasang bolt on vs the popular 320d tip switch of 150-200? So stuck on the fence of which shld I do? Another question is, any e90 owners swap out their intakes system? Ie gruppe/Simotas.. Any idea where can I get it done n rough pricing? Sorry virgin e90lci looking for some minor parts swap but noob owner!
