A brand new direct replacement high performance aluminium intercooler from AlliSport. This intercooler has been designed to directly replace the original smaller intercooler on the Land Rover Defender, Discovery or Range Rover 300Tdi engine and has 50% more surface area than the original. Combined with the correct tuning (instructions included) power will increase from 111bhp standard to 135bhp with a similar increase in torque. The greater cooling capacity will allow up to 20% increase in power and torque in the lower and mid-range revs. Customers regularly report 10-12% gain in economy. There are minimal alterations necessary to the vehicle, as the kit is a direct replacement. 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. As your vehicle is 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 EGT or combustion temperature is reduced dramatically Specification:- 50% greater surface area external dimensions as per original intercooler 65mm Thick special high performance vacuum brazed core Fully TIG welded in house Makes full use of the space available whilst keeping external dimensions the same Tuning instructions included
