E36 Fog Light Brake Ducts

Put those fog light openings to work.

Fits BMW E36 models with M3 / M Performance Bumper (fog light openings required)

Stop Wasting That Free Airflow

• Purpose-built for the M bumper: Designed specifically to mount in the E36 M3/M Performance bumper fog light cutouts — no drilling, no fabricating, no excuses.
• 74 mm (2.9") circular outlet: Sized to feed your braided brake cooling lines or flexible ducting directly to the rotors where the heat actually builds.
• Plug & play install: Drops in with minimal effort. Secured with adhesive or epoxy for a permanent, rattle-free mount. Minor trimming may be required to dial in the cleanest possible fitment on your specific car.
• PETG-CF construction: Carbon-fiber-reinforced PETG handles the underbonnet heat and road debris that would destroy cheaper prints — won't warp, sag, or crack.
• Clean OEM aesthetic: Matte black finish blends with the bumper. Looks intentional from the factory, not bolted-on as an afterthought.
• Track or street ready: Whether you're managing rotor temps at a track day or just keeping things cool on an aggressive street build, these deliver.

Install Notes

• Designed to seat directly into the fog light openings of the E36 M3/M Performance bumper.
• Retention method: These ducts are designed to be secured to the bumper using a suitable adhesive or epoxy (e.g. 3M automotive adhesive, JB Weld, or equivalent). Ensure mating surfaces are clean and dry before application.
• Minor trimming of the bumper opening or duct tabs may be needed to achieve the tightest, most precise fitment on your specific car — bumper tolerances vary, even between genuine M bumpers.
• 74 mm OD outlet is compatible with standard 3" brake cooling hose/ducting.
• Tolerance-matched to the M bumper cutout — fit may vary slightly with aftermarket bumper replicas.

This is an aftermarket part. These ducts are adhered to the bumper using adhesive or epoxy — no mechanical fasteners are included or required. Minor trimming and fitment modifications may be necessary to properly fit your specific bumper. Bumper tolerances vary between genuine and replica M bumpers, and some modification work should be expected to achieve optimal results. We are not liable for damage from installation or use.
