Airtec rear differential cooling duct- GR Yaris

Differential cooling duct upgrade suitable for track or fast road use. The duct offers a simple solution to improving the differential’s cooling ability, which helps to ensure rising temperatures don’t cause any damage.

How it works

When the oil inside the differential gets hot, its ability to lubricate and protect both the gears and LSD is reduced. This is more likely to occur during extended periods of hard use, such as on track, so it is beneficial to stabilise and reduce temperatures in order to limit premature wear.

The AIRTEC Motorsport cooling duct works by directing fast-flowing air passing underneath the car towards the differential’s cooling fins, which rely purely on air flow to shed heat effectively. By providing more sustained air flow to these fins, the differential’s cooling capacity and ability to withstand heat soak is increased, which therefore allows it to better control operating temperatures in comparison to standard.

Our updated Version 2 design is made from high-quality, injection moulded plastic that is both lightweight and durable. Finished in red, the duct is a direct fitment that requires no additional drilling or cutting to fit, and comes complete with all the correct fixtures and fittings, as well as detailed instructions.
