Good and easy
Installed few days ago on my bmw 118i year 2009. No modification required for the installation, it fit perfectly inside the air filter box. Very easy for installation. The engine feels that can breathe more and it run more smooth, about noise it increased just a little bit. I not yet run enough km with it to can talk about Fuel consumption, however i’m very happy with this product, and it’s working well here in uae with 45degrees C.

K&N Waschbarer Tauschluftfilter
Der K&N E-2021 waschbare und wiederverwendbare KFZ-Tauschluftfilter hat sich als eine hervorragende Investition erwiesen. Die Möglichkeit, den Filter zu reinigen und wiederzuverwenden, macht ihn nicht nur umweltfreundlich, sondern spart auch langfristig Kosten im Vergleich zu herkömmlichen Einweg-Luftfiltern. Die verbesserte Luftzufuhr trägt dazu bei, die Motorleistung zu optimieren. Die hochwertige Verarbeitung von K&N steht für Zuverlässigkeit und Langlebigkeit. Insgesamt bin ich mit der Leistung und der langfristigen Wirtschaftlichkeit des K&N E-2021 Luftfilters sehr zufrieden.
