Defender Upgraded Intercooler Installation

To improve off road and highway handling I installed an uprated double core intercooler from Allisport as my Defender was getting a little on the sluggish side.

The installation was quite easy though the radiator surround frame needed to be modified slightly to allow for the greater depth of the Allisport intercooler.

I had my Defender professionally dyno tuned which included having the fuel and boost settings adjusted. As a result EGT’s were reduced by approximately 100 degrees Celsius during demanding driving.

The 200tdi Uprated Double Core Intercooler promoted an 80% increase in surface area which Allisport claimed “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”. My results prove this to be an accurate claim.

I gained 15hp with the upgraded intercooler and correct tuning. It was well worth the expense. It’s like driving a new car. I can drive some hills in 4th gear where previously had to change down to 3rd. 🙂
