The advanced design and sleek features of the Active Autowerke Supercharger System include a front mount air-to-air intercooler system with a separate oil cooler for the supercharger unit's independent oil system.

The Active Autowerke Supercharger Plenum replaces the factory air box and is designed to have an OEM-type look with custom finishes available at the customer's request. The Plenum has been designed with eight high-flow velocity stacks, and large three inch intercooler piping to supply cooled air. 

The custom Active Autowerke Filter mounts to the supercharger unit and is enclosed in a custom intake box engineered to incorporate factory design while forcing cool air to the air box.

The standard finish on the Active Autowerke Supercharger Plenum is a matte wrinkle black, custom colors are also available for an additional cost.

The Active Autowerke Supercharger System is powered by a Rotrex C38-92 Supercharger Unit mounted with a custom CNCed bracket that uses a dedicated drive belt system, while eight high flow fuel injectors are used to supply the additional required fuel.

Active Autowerke's Performance Software, available for 91-93 octane, race gas, and octane levels unique to other countries, is carefully calibrated, and is at the heart of the system to provide an unparalleled driving experience. Keeping within the factory's OBDII parameters, the Active Autowerke Supercharger System ensures consistency for everyday driving.

Fantastic to do 1 run and power multiple loads
Size: 30ft, Style: 6C-18AWG
Great for wiring up multiple loads. In my case multiple lighting with different switches so that I can turn them on independently from one another.

Durable, very nice wiring harness.
Size: 50ft, Style: 6C-18AWG
I am updating an emergency vehicle and am using this to run the equipment. It’s easy to work with and good thick wire. Came with nice little Velcro straps for keeping the roll together. The finish is nice on the outer casing. Nice gloss black. Excellent product. In fact I bought another 50 foot roll. And the prices for this is extremely good. Glad I found this wiring.
