That's my point! Earlier E9x M3's had a more restrictive charcoal lined air filter. More recent models have the same euro edition air filters, which are less restrictive. Lets be honest here: There are NO MAJOR GAINS in horsepower by changing the air filter on latter models. I like how your filter is built (excellent build quality) and the intake sound that comes with it, though. I will be buying it again.
