K&N filter for 340i

Seattle135is · 05-27-2019, 02:58 PM

So, one of my first mods is to swap out the air filter to K&N - I bought one online from Amazon - K&N 33-3051 - and I checked K&N's website and it's indeed 33-3051 - but when I compared it to the original, it was significantly smaller. Am I missing something?

Smaller in what regard? Did you try to install it?

Should have searched the forums first...you'll find that KN filters really don't do anything and are a waste of money.
