K&N has been leading the performance filter
industry world wide for over 35 years.
K&N's Filtercharger filter actually improves air flow over the
stock BMW filter media, in turn releasing extra horsepower and even
improved gas mileage. There's no downside to fitting a K&N on
your ///M
The secret lies in the K&N unique-design and construction. A
staple of high-performance cars for years; all of K&Ns filters
are lifetime warranted for 1-million miles and can be cleaned and
reused for that amount of time! We have tested and found these
filters are a great upgrade for the S63.

VAC Dyno:
We tested these filters out and found that they quickly made an
average of around 10WHP & Tq at the wheels, with max gains of
11WHP & 18ft/lbs at the wheels on our Mustang Dynomometer at 58
degree F ambient temps on the stock ECU tune.
That makes these filters a great buy!!! |
