Free Flow High Performance Air Filter System
We are currently out of both the 4030 and 4031 air filter kits. Watch this page for updates.
This quality intake system replaces the stock airbox, (where
your air cleaner is housed) and allows the engine to breathe
easier for added performance and horsepower. Maintenance costs
are reduced because the K & N filter is washable and reuseable
with the K & N filter recharging
kit and come with a 1,000,000 mile warranty. Most cars see
a 3 - 5% increase in power from this system alone.

#4066 This upgraded system
is designed to shield the air filter from under-the hood heat.
It is a formed housing that meets up flush to the hood when the
hood is shut. This system works on all E36, 6 cylinder models
including the M3. It's made of black gelcoat fiberglass and is
specifically designed to block engine heat from the air filter.
The system is complete with a 9" K&N filter, all needed
hardware, and complete instructions. The same style clamps are
included that BMW uses under the hood. Having a removable plug
in the back of the housing lets one unit work on the 1992-95
E36 models, as well as the 1996-99 E36 versions. (Early models
had an air temperature sensor attached to the factory air box).
No holes get drilled in the car to install this system. Power
gains can be felt, since the filter is getting constant cooler
air. |
