Good evening together I was with the friendly one today to pick up my second key and there I fell in my hands while waiting, an accessory catalog. I noticed the tuning kit! Can the air filter also be bought individually?? There is a sports exhaust pipe cover, can it do something or rather not? (I already have the mini accessories for 180€) Can I not be friends with the reprogramming of the ECU anyhow. I have read, then my mini gets a n new cylinder head?? Furthermore, I would like to have more sound in the car, what do you think of the packages of autohifistation? Find the solution of Alpine and H&K at friendly, but too expensive. My dealer also advised me of the retrofit sets of Mini, he has already had bad experiences.
