Stage 3 – P10 Performance Package

Revolutionise torque and power with our Stage 3 tuning package for Land Rover Defenders. This upgrade includes all the features from our Stage 2 package with the addition of the ARKHAM intercooler and upgraded silicon hoses. The high flow uprated intercooler ensures the engine gets the maximum amount of cool, dense air possible.

An integral part of any turbo engine, the ARKHAM intercooler has evolved through many stages since its first incarnation in 2001, creating one of the best products available. It fits perfectly in the original aperture, taking up no more room than the standard unit. And yet it’s been designed to allow for the maximum surface area to increase the speed of cooling. This happens through the significant dissipation of heat without the need for any fabrication or creation of additional space.

The ARKHAM intercooler has 76 sqm of internal surface area, compared to 16 sqm on a standard Land Rover intercooler. Benefits include all alloy construction, louvered cooling fins, extruded tubes with braised foil and part folded tanks. Also, CNC machined inlet and outlet tubes, removable pins for ease of fitment and the ARKHAM branded, stainless-steel bonnet catch core protector.

• ARKHAM Performance ECU Remap
