TECHNICAL DATA

Following an extensive development process, AIRTEC Motorsport are proud to launch our auxiliary radiator and turbo cooler kits 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 we designed a series of new products to address the cooling issues when pushed to the limit. This additional radiator fits neatly behind the fog light (requires removal) and utilises laser-cut aluminium ducting to force cold air through the radiator. To create a flow path and further improve cooling, air then exits via the inner arch liner (requires cutting). A pre-cut mesh shield is supplied for both the front and rear to protect the radiator from road debris damage.

The radiator is plumbed directly into the existing oil/water heat exchanger system to improve the car’s overall capacity and cooling ability, allowing it to maintain a steady temperature for longer during hard use.

This can fit with any of our intercooler or oil cooler combinations to create the ultimate cooling package. The comprehensive kit also features laser-cut and powder-coated brackets, high-quality Pro Hoses silicone lines as well as all fixtures and fittings, and detailed fitting instructions.

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.

Key features:

  • Designed and developed in the UK specifically for the Yaris GR
  • Improves car’s cooling capacity and ability

I buy these again and again through the years!
Size: Medium, Color: Austin Brown Assorted (6-pairs)
Love these. After a year or two I wear holes in the bottoms because I wear them so much. Worth the little bit higher price because of the fit and comfort. Love how they are truly no show

Good quality but tight on toes
Size: 6-10, Color: White/Assorted
These are great socks that stay in place, but they scrunch my toes together like crazy. My feet are normal width. When I first started wearing them I noticed my feet would ache after an hour or two.

My New Favorite Socks
Size: 6-10, Color: Halo Gray/Assorted
These have quickly become mine and my mom's favorite socks. We wear them with tennis shoes, Hey Dudes, and more. The fabric is incredibly soft and comfortable, they do not budge/fall in my shoe, and are extremely well made. I have become so attached to these socks, that I no longer want any other brand.

LOVE THEM!!
Size: Small, Color: (001) Black / Black / Castlerock
LOVE! These socks are so comfortable! I wear a 5 in women's and a 3 in big kid shoes. The small fit me perfectly. I see where some say they run small but I can't say that was an issue for me. They are "snug" but thats what you want with a no show sock. I feel they have support vs the ones i used to buy at Walmart. They are very soft! I am actually buying more today and throwing my other ones in the trash!
