E46 M3 Bumper Brake Duct - Digital Download

This product is a Digital Download consisting of STEP files for the parts shown and described below. Assembly instructions and parts list are included in a pdf with file purchase.

As used on our B46 race cars! Direct-fit lightweight brake duct set for use with an E46 M3 bumper. We designed these to easily bolt in and provide more downforce and less drag than traditional brake ducts in the fog light area.

These reuse the factory fog light mounting provision in the bumper. Compatible with any 3" duct hose.

Please note: If using a non M to M bumper adapter kit, there may be interference at the mounting points for the ducts.

Includes: 

• .step files for both sides
• pdf instructions

Printing Notes:

The parts as pictured, were produced in solid black SLS PA12.  

If you send these to a third party to have printed they may alert you that certain aspects of the part can warp or are too thin to guarantee print quality. This is normal and you can tell them to print the part as designed and we have had many of this part printed without issue if you follow our guidelines. However we are not responsible for printing errors and that is always a risk with 3D printed parts.

We do recommend using a reputable print company. For one off or small batch prints we use Craftcloud which is a marketplace of 3D printing companies. For PA12 SLS parts we have had very good service from 3DPnxt (video attached).  If you have not used Craftcloud before you can use our referral code to save 10%: REF7MYQTYFU
