AS112-AUTO - Uprated Intercooler for Land Rover Defender TD5 or TDCi Puma with Close Fitting Winch or Auto Conversion by Allisport

New ultra efficient uprated intercooler for Defender TD5 & Tdci

Suitable for auto conversions using an oil cooler below the intercooler or close mounted winch

Featuring our special L.I.F.T (Louvered Internal Fin Technology) Hi-Flow core design for ultimate reliability and efficiency.

Lifetime warranty!

Along with many other products we manufacture, all AlliSport intercoolers are covered by a lifetime warranty – we are so confident this is the best Defender intercooler available today.
Often copied, but never bettered, our 2020-Pro version is further revised and improved with stronger design and improved air flow.

Substantially larger and more efficient than the original crimped end tank design which is prone to corrosion and splitting, we have designed this version with larger pipe connections to allow a higher flow of the larger engines. 57, 64 and larger versions available (51mm standard for TD5, Tdci)

Easy to install to the original radiator – with only very minor modifications required. Also suitable for cars fitted with Air Con.

Each unit undergoes final inspection and pressure test to over 30 psi under water, before being dated ready and packed for dispatch around the world.
During our design process, we tested the product to over 120 psi with no failures.

This core size is capable of cooling over 600 bhp, as proven on our customers World Rally Cross, Rally Raid and Gymkhana cars.

We conceived our original design early in 1999 on one of the first TD5 Defenders to be modified (which by the way is still in use with its original intercooler!)
Now, completely designed on Solid Works, with Laser cut end tanks and mounting brackets, CNC folded and TIG welded individually by hand in house.

Our design uses high grade 5000 Series sheet metal end tanks, folded from a single piece to eliminate splitting.

This design is lighter and more efficient than the heavy cast models on the market.
Lighter weight means better heat rejection, as there is less material to act as an insulator meaning less heat soak and better recovery times in between boost cycles.

Despite specialising in intercooler manufacture for over two decades, we have had our design independently tested in the UK against various designs on the market, including heavy cast designs from the UK and around the world.
This independent testing consists of a program of tightly controlled tests including heat rejection, efficiency, recovery, high pressure test cycles, pressure drop, charge air flow and air flow over the core externally. Results are derived from the average of at least 10 readings per condition.

You will notice all our intercoolers are plain aluminium with no coating.
This is because any coating acts as an insulator thus reducing efficiency, plus we pride ourselves in the finish of our products and have no need to cover up any substandard finish!

We have taken a great deal of time to ensure these intercoolers are easy to fit; a simple replacement for all Defender Td5, 2.4 and 2.2 Tdci models with or without air conditioning.

The increased cooling capacity together with the appropriate electronic tuning can typically allow at least 45% power improvement, with a similar torque increase.
Fuel economy improves by, on average 10% with a reduction in cylinder head thermal stress. Thermal stress is actually reduced as the EGT or combustion temperature is reduced dramatically. Power and torque can be increased further with special turbos and improved air flow products.
