Le filtre KN est un produit de grande qualité et son montage très facile. Il suffit d'avoir les bons outils pour le montage. Il remplace efficacement le filtre d'origine en lieu et place. Il peut être nettoyé tout au long de la durée de conservation de la voiture ce qui permet de faire beaucoup d'économies.A recommander pour les spécialistes soucieux des performances pour leur voiture. Attention à la référence car le site du fabricant en suggère un autre qui ne s'adapte pas.

It maybe placebo but the damn car sounds much better. The acceleration too is much better. It could be my imagination but i think this made my car perform better than the OEM filter.

I've been using K&N filters forever, great airflow and very good filtration. good for the life of the vehicle, just clean it every once and a while, reoil and you're good to go. well worth the money. also worth noting, it gave me better throttle response on my BMW 535i
