AIRTEC Motorsport Stage 3 Oil Cooler for Toyota GR Yaris

Description

This is our biggest oil cooler kit to date offering a huge 51% increase in volume over our Stage 1 oil cooler. Spanning across the entire front grille area for maximum air flow, the comprehensive kit also features new laser cut ducting to force cold air through the cooler.

TECHNICAL DATA

Following an extensive development process, AIRTEC Motorsport are proud to launch our Stage 3 oil cooler kit aimed at modified Yaris GR owners who require the ultimate cooling package to maintain steady running temperatures on track or fast road use.

The challenge
When modifying the Yaris GR to increase power and torque at more extreme levels, an unavoidable byproduct is the additional heat level that’s transferred to the car’s cooling system. During hard use this can become a substantial issue, as we found on our own 400bhp+ Yaris GR demo car whilst testing on track. After sustained periods of hard use (similar to a round of racing), coolant temperatures would eventually reach 102 degrees, which was enough to trigger the aftermarket ECU’s safety features, putting the car into limp mode. Similarly, oil temperatures reached 123 degrees. We needed to address the car’s entire cooling system if we were going continue to modify and track our Yaris.

The solution
Developed in-house at AIRTEC HQ in the UK, this is our biggest oil cooler kit to date offering a huge 51% increase in volume over our Stage 1 oil cooler kit. Spanning across the entire front grille area for maximum air flow, the comprehensive kit also features laser-cut aluminium ducting to force cold air through the cooler. This allows it to fit with our Stage 3 intercooler kit (our Stage 1 oil cooler does not fit with the Stage 3 intercooler) to create the ultimate cooling package.

The package includes a large AIRTEC Motorsport oil cooler with ducting, bespoke laser-cut and powder-coated brackets, high-quality braided hose lines with Aerotec fittings, and all fixtures, including instructions, for a simple bolt-on installation.

The testing
We went back to the track fitted with both our turbo and auxiliary radiators, as well as our larger Stage 3 oil cooler fitted, and were able to see a 10 degree peak drop from the coolant temperature, reducing to a much safer constant 92 degrees whilst oil temperature reached a maximum of 94 degrees thanks to a mix of the larger oil cooler allowing more surface area to cool the oil and the turbo cooler being able to reject more heat for the car’s original oil/water heat exchanger.
