AIRTEC Motorsport Gearbox Oil Cooler for Honda Civic FL5 Type R

Technical Data

As part of our expanding Honda product range, AIRTEC Motorsport are proud to launch our uprated gearbox oil cooler suitable for track or fast road use. 

The Challenge
When modifying the Civic FL5 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 coolant temperatures can increase enough to trigger the ECU’s safety features, reducing torque or even putting the car into a limp mode. As a result, we wanted to address the car’s entire cooling system.

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. To date, there is no other company offering a gearbox oil cooler on the market, but our kit hasn’t just been designed to help cool the transmission, it also helps remove heat from the engine’s cooling system, which helps reduce crucial operating temperatures. 

This is because from the factory, there is a simple heat exchanger/oil Modine located by the gearbox that uses the engine’s coolant to help cool the gearbox oil. 

But by adding an external oil cooler into this existing loop, both gearbox and engine running temperature are effectively reduced. The substantial increase in gearbox oil volume thanks to the cooler and lines also help keep temperatures lower for longer.

The oil cooler itself mounts neatly to a supplied replacement lower brace bar behind the rad pack that is stronger and more rigid than the original Honda brace it replaces. 

The comprehensive package also features an air duct panel to direct fresh air to the oil cooler. Made from lightweight aluminium that is laser cut for a perfect fitment, the panel features more ventilation slots for additional passive cooling under the engine and uses all the original fixings for a direct replacement. 

Finished in a high-quality black powder coat, the kit requires no trimming or cutting and can be reverted back to standard. The fitting kit includes oil lines and fittings, as all fixtures required to fit, including a detailed installation guide.
