High performance direct replacement “Double Core” intercooler for Land Rover Defender, Discovery or Range Rover Tdi engine.
This intercooler has been designed to replace the original smaller intercooler and has 80% more surface area than the original.
Ideal for customers with fitted close mounted winch bumpers where it is not possible to fit our larger front mounted intercooler.
This model is a great compromise between our standard uprated model and the larger Option 2 front mount and is also suitable for cars with AC.
Combined with the correct tuning (instructions included) power will increase from 111 bhp standard to approximately 141 bhp with a similar increase in torque. Figures are taken from our customers own rolling road tests.
The greater cooling capacity will allow up to 27% increase in power and torque in the lower and mid-range revs and improved throttle response, customers regularly report 10-15% gain in economy.
Please note, you will need to adjust the original intercooler/radiator surround frame to install this intercooler or purchase our replacement frame.
Because the intercooler is far more efficient than the standard item, the fuel pump will need setting to compensate for the change in mixture. The settings are straightforward and are covered in the comprehensive fitting instructions supplied with the kit.
As most Tdi vehicles are not electronically controlled, there is no ECU to remap, so we optimise the fuel and boost settings to match the intercooler mechanically.
Cylinder head thermal stress is actually reduced as the combustion temperature or EGT is reduced dramatically
115mm thick special high performance L.I.F.T (Louvred Internal Fin Technology) controlled atmosphere brazed core, TIG welded by hand in house.
Internal turbulators increase cooling capacity

New developments in antifreeze technology has meant that certain cars now being built using
Organic Acid Technology (OAT) or Hybrid Organic Acid Technology (HOAT) Formulations. These new
types of antifreeze are designed to have an extended service life of 5 years or 150000 miles.
These new grades of OAT have an anti-corrosion component in them which can be harmful to
Silicone and rubber components. Due to this Roose Motorsport have introduced a new OAT liner
which we apply to all our coolant hoses to comply with Euro 6 regulations.
