Following an extensive development process, AIRTEC Motorsport are proud to launch our oil cooler kit aimed at FK2 Civic Type R owners who require the ultimate cooling package to maintain steady running temperatures on track or fast road use.

The Challenge
When modifying the FK2 Civic Type R to increase power and torque, an unavoidable by-product is the additional heat level that’s transferred to the car’s cooling system. During sustained hard use, this can become a substantial issue, as temperatures can increase enough to trigger the ECU’s safety features, reducing torque or even putting the car into a limp mode. 

The Solution
Developed in-house at AIRTEC HQ in the UK we designed an oil cooler to help address the cooling issues when pushed hard. This cooler fits neatly behind the fog light (requires removal) and utilises our bespoke CAD-modelled air duct to force cold air through the core. 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.

This can fit with our intercooler and auxiliary radiator/turbo cooler to create the ultimate cooling package. The comprehensive kit also features laser-cut and powder-coated brackets, high-quality braided lines with AN fittings as well as all fixtures and fittings, and detailed fitting instructions.

Driver Comments: 
“This was an extremely hot day and car coped very well. Before the auxiliary radiator and oil cooler were installed I would normally get approximately 5 to 6 laps, which is about 8 to 10 minutes of hard use before the oil temperature rose to around the 126 to 128°C. With the coolers installed, I can run at least 10 to 14 laps, which is over 20 minutes of hard use, and oil temperatures don’t normally go above 115°C."

Also a major advantage is that I can repeat that all day long, whereas before I found that once the temperature of the oil got really hot it would normally not cool down enough for the rest of the day,  so it meant I ended up doing only 3 to 4 laps before the temperature rose again, as the oil never fully cooled down and seemed to heat back up quicker.”
