Differential Cooling Air Duct suitable for BMW E36 (188 Differential)

Maximum performance doesn't end with the engine – the differential also needs cooling, especially in harsh racetrack conditions.
Our specially developed air duct ensures that the airflow is specifically directed under and behind the differential to effectively lower the temperature and increase durability. The component is simply bolted to the differential, no removal required!

Especially in motorsports, the differential gets extremely hot – with this system, you bring functional cooling at a near-OEM level to your setup.

Product Details

• Suitable for BMW E36 with 188 differential
• Made from high-quality plastic
• Heat & UV resistant – no deformation or embrittlement
• Directs airflow under and behind the differential
• Developed for racetrack, drift & track tools
• Plug & Play mounting points (vehicle-specific)
• Including mounting material: 2x mounting clamps, screws & washers

Why Differential Cooling?

In stock condition, the differential is barely actively cooled. However, under continuous load (trackday, drift, circuit), temperatures rise sharply.

The consequences:

• Loss of performance due to overheating
• Increased wear of oil and bearings
• Risk of damage under extreme loads

👉 With this air duct, the airflow is specifically used to cool exactly where it matters.

Your Advantage

✔ Effective cooling without complex additional systems
✔ Significantly better temperature control during racing
✔ Durable, motorsport-grade material
✔ Clean, well-thought-out solution instead of improvised air ducting

❗ Note

• Developed for motorsport use
• Installation should ideally be carried out by a specialist workshop
• Fitment should be checked depending on setup and lowering
