The K&N drop in filter was a great addition to my Twin Turbo 2012 BMW 328i. Immediately I noticed the difference in smoother acceleration and gear changes. The extra power is nice too when you put the car in Sport Mode and let it have it.

Bien, le moteur de ma BMW série 3 GT à l'air de mieux respirer.
Michel Empain, Mons, Belgium
Bonjour, Pour donner mes impressions, mon compteur affiche au compteur 5 cv de plus, le moteur respire mieux, cela se voit à la température du moteur. Sur le plan consommation, je n'ai pas encore vu de différence. J'entends un léger bruit de sifflement supplémentaire, qui n'est pas désagréable... Et surtout je peux maintenant laver mon filtre et ne pas en payer un nouveau dès que je ferais mon entretien. Bonne journée, Michel

Very simple to fit, literally 2 minutes. Makes a nice sucking induction noise on wide open throttle. Good purchase.
