Description
This kit has been designed to address the weakness of the stock oil cooler – the cooler fitted to your car from Audi is aluminium, but the fittings on the ends of the cooler hoses are steel. The result is corrosion between the two different metals which cracks the fittings over time, causing a slow oil leak that gets worse with age, and eventually ends in a catastrophic failure of the oil cooler lines – and if you are unlucky, the engine too.
Due to the corrosion setting in on the lines, they usually cannot be removed from the oil cooler without damaging it. This results in the need for the oil cooler and both lines to be replaced at a cost of over £1100 from the dealer, before you factor in consumables and labour to change the parts.
Our solution uses tried and test products. It is a full replacement right from the fitting on the engine block which is precision made from 6082 billet aluminium, and then anodised to prevent any possibility of corrosion.

This fitting leads to -12 AN Hose Technik black anodised aluminium fittings on Hose Technik braided lines with black overbraid.
Cooling is accomplished by a 19 row Setrab oil cooler, the same manufacturer that supplies Audi and several F1 teams, again with a black finish. All the mating parts are similar materials and are tried and tested in Motorsport – there is no fear of corrosion affecting the fittings after a few years of use. The cooler is supported on a laser cut and powder coated frame that also holds the Audi fan control module in place. With everything finished in black, it makes for the ultimate stealth installation and unless you know what you are looking for, you won’t see it.
The original remit of this replacement was to do away with all the troublesome Audi parts, which this kit accomplishes, but by relocating the oil cooler slightly higher than stock, we have also reduced the chances of damage from road debris.

All parts needed for installation are included – bolts, nuts, washers, brackets, and full instructions, though you will need up to additional 2 litres of engine oil to account for the loss from removing your old oil cooler, and for filling the new cooler and lines.
