FORGE Engine Oil Cooler for the Audi RS4 4.2 (B7 2006-2008) FMOCRS4
Product Description
This kit has been designed to address the weakness of the stock oil
cooler – the cooler fitted to your car from Audi is aluminum, 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.
