aFe Magnum FORCE Stage 1 Cold Air Intake System. This intake kit
replaces your restrictive factory air box. It features a black
composite/molded tube, 16-gauge powder-coated steel heat shield, trim
sealed to seal out hot engine air, and a custom aFe brand cotton
filter.
This intake improves airflow by 90% for better
acceleration and responsiveness. It does this by replacing your flat OE
air filter with the largest high-flow, high-performance 360 degree
radial flow filter that will fit within the space provided on the MZ4,
as well as a custom designed intake tube that accelerates airflow to
the throttle. The filter is also washable and reusable. aFe has
reported gains of 11 hp and 10 lb/ft torque @ 4900rpm on the S54
powered MZ4 roadster/coupe. Installs in less than an hour using simple
tools and factory mounting points (no cutting, drilling, or
modifications required!). Instructions included. For even more benefit,
we recommend upgrading your belt driven engine pulleys to our TMS Power
Pulleys.
With aFe, enthusiasts are no longer locked into an oiled or dry filter
only option when choosing an intake system. aFe offers their intake kits with either a Pro Dry S oil
free filter or their Pro5R oiled cotton filter. aFe intake kits
also include all necessary hardware and easy to follow
installation instructions to get you buttoned up and back on the road
in no time.
