Thanks for the comments. It was easy to install the BMW Performance Air Intake, and only you know that you got it under the hood.... Not even your significant other will be suspicious
.... and remember the actual gains in performance is only in your heart!!!
PS: for replacement air filter I use oil impregnated synthetic fabric air filter by K/N. Every time I bring in for CBS (condition based service) at dealership I have to argue with service manager that I don't want them to replace the air filter element... they are really retards since this is made a genuine BMW aftermarket vendor in UK!!!
The CBS interval for air filter element replacement is every THIRD oil replacement, that means every 50K miles or about three years... and that is CRAZY. I washed the filter every year and according to my driving habits it seemed to be more than adequate. I have driven to north to Prince Edward Is, Halifax and south all the down to Vero Beach.
