B5 Aluminum Core Support
Base Unit
An aluminum core support to replace the OEM fiber-plastic unit. This offers more rigidity for mounting auxiliary or aftermarket components, offers more room for service work under the hood, and drastically improves the appearance of your build. The base unit has mounting provisions for the headlights, radiator, lower fender connection, and optional brackets. The base unit is designed to offer more space for aftermarket side mount intercoolers; fitment may vary by brand.
It comes with interchangeable lower radiator mounts that fit B5 A4 and S4 radiators and can be replaced with mounts to fit other radiators or move the radiator to an alternative location. The upper radiator mounts are CNC machined from 6061 aluminum and are also interchangeable, with options to move the radiator to alternative locations built into them.
B5 Core support base unit is made from 5052 and 6061 aluminum and TIG welded with zinc coated steel rivet nuts for M6x1 threaded connections.
Hood Latch Bracket
B5 hood latch bracket is made from 304ss and TIG welded, fits OEM hood latch mechanism. This bracket is optional for those who decide to use hood pins.
Snub Mount Bracket
B5 Snub mount bracket is made from 304ss and TIG welded, fits OEM and aftermarket buckets. The snub mount bracket has mounting provisions for both the 2.7t and the 1.8t, however the 1.8t will need the snub mount stub to mount the bushing.
B5 Lower Cross Bar is made from 304ss and TIG welded. It replaces the snub mount bracket with a bare tube to reinforce the core support if desired and offer additional opportunities for mounting other components.
Fan Shroud
The OEM fan shroud on the B5 is built into the OEM core support, with the main fan being mechanical and the aux fan electric. There are three options for a fan shroud on the aluminum core support;
- No shroud - Radiator fans are attached to the radiator via pull through style zip ties or comparable. Whatever size aftermarket fan that fits the radiator's core can be used. Wiring of the fans will be custom.
- Radiator mounted fan shroud - A shroud that attaches to the radiator core's flanges via bolts or spring clamps. Uses one aftermarket 12" fan and one aftermarket 10" fan. Wiring of the fans will be custom.
Installation is similar to that of the OEM unit, instructions are available below, download is a single pdf file.
