AIRTEC Motorsport performance intercooler for Defender TD5 and Puma 2.2 / 2.4 TDCI models. The larger 11.7L single-pass core gives 134% more capacity and 55% greater frontal area than the standard Defender intercooler, providing substantially increased charge-air cooling capacity for tuned, remapped and hard-worked engines. Cast aluminium end tanks are used rather than fabricated sheet-metal end tanks, giving a stronger, cleaner construction with better-controlled internal airflow through the intercooler core. The original 50mm boost hose connections are retained.

Fitment Notes
The larger intercooler requires minor trimming of the original plastic radiator mounting blocks during installation. On Defenders without air conditioning, the slam-panel support stays also need to be bent slightly forwards to provide clearance for the deeper intercooler core.

Brand
Airtec Motorsport
AIRTEC Motorsport performance intercoolers for Defender, Discovery and Range Rover Classic, covering 200TDI, 300TDI, TD5 and Puma TDCI engines.
AIRTEC intercoolers use large bar-and-plate cores with flowed cast end tanks, giving a strong, well-finished alternative to the fabricated sheet-metal designs common on many aftermarket intercoolers. Twinwoods stocks AIRTEC where the larger core and vehicle-specific fitment make sense for tuned, remapped and hard-worked Land Rovers.
AIRTEC Performance Intercoolers
AIRTEC Motorsport develops vehicle-specific intercoolers with larger cores, increased frontal area and greater cooling capacity than the standard units they replace. The Land Rover range includes side-mount upgrades for 200TDI and 300TDI engines, full-width Defender intercoolers and larger intercoolers for TD5 and Puma TDCI models.
One of the features we particularly like is AIRTEC's use of flowed cast aluminium end tanks. Unlike intercoolers built around folded and welded sheet-metal tanks, the cast construction allows the internal shape to be formed around the airflow path through the core while also producing a strong, rigid and tidy finished assembly.
Land Rover AIRTEC Fitment
The AIRTEC intercoolers stocked by Twinwoods cover Defender, Discovery 1, Discovery 2 and Range Rover Classic applications across 200TDI, 300TDI, TD5 and Puma TDCI engines. Individual product pages give the relevant fitment details, installation notes and any manual, automatic or air-conditioning restrictions before ordering.

Twinwoods 4x4 ships Land Rover parts across the UK and around the world. We regularly send parts overseas and use trusted tracked courier services so UK and international customers can order with confidence.
Standard UK shipments are normally sent with DPD. UK orders containing oils or fluids are normally sent with DHL where required, because some carriers restrict liquid shipments.
Worldwide delivery is available through DPD and DHL Express, depending on the destination, parcel size, weight and available courier services. Add the parts you need to your basket, enter your delivery address, and the checkout will show the available delivery options and prices before payment.
Free mainland UK postage and packaging is available on eligible orders over £99, subject to our delivery terms and conditions.
- Changed your mind within 14 days? UK and EEA consumers have statutory cancellation rights. Tell us within 14 days of receiving your order, then return the goods within the following 14 days.
- Need longer? Eligible products can be returned under our voluntary extended returns policy. Contact us within 60 days of delivery and, once the return has been agreed, send the goods back within 14 days.
- Extended returns must be unused, unfitted, complete and suitable for resale as new. Goods must be undamaged, unmarked and uncontaminated, with all components and accessories supplied and their original product packaging where this formed part of the supplied product.
- A £10 handling charge applies to extended returns. This is charged once per return consignment, regardless of how many eligible products are returned together. It does not apply where your statutory cancellation rights apply.
- Return carriage and safe packing are your responsibility for change-of-mind returns.
- Managed UK returns: where suitable, we can provide a convenient prepaid tracked return service with straightforward drop-off, proof of handover and tracking linked to your return. The cost will be advised before it is arranged and may be deducted from your refund.
- Please do not fit or attempt to fit a part unless you intend to keep it. Fitting, attempted fitting, contamination, damage or excessive handling can substantially reduce the value of the goods. A product which has been fitted or used will not normally qualify for our voluntary extended returns policy.
- Faulty, damaged or incorrectly described? Contact us first. We will advise the appropriate return method and will normally provide a prepaid return service or cover reasonable agreed return costs.
Returns – quick FAQs
How long do I have to return an item?
For UK and EEA consumers, statutory change-of-mind cancellation rights also apply: tell us within 14 days of receiving your order, then return the goods within the following 14 days.
Which products qualify for 60-day returns?
Products purchased for £250 or more are not automatically covered, although we may agree to accept them for return at our discretion. Eligibility is based on the price of each individual product rather than the total order value.
Is there a charge for an extended return?
This charge does not apply where the return is being made under your statutory cancellation rights.
Who pays return carriage?
If an item is faulty, damaged or incorrectly described, contact us first. Where return is reasonably required, we will normally provide a prepaid return service or cover reasonable return costs agreed with us.
What condition must an extended return be in?
Can I fit a part and then return it?
Once a part has been fitted or an attempt has been made to fit it, it may be marked, contaminated, damaged or otherwise unsuitable for resale as a new part. Fitted or used goods will not normally qualify for our voluntary extended returns policy.
Where statutory cancellation rights apply, handling beyond what is reasonably necessary to inspect the goods may result in a reduction to your refund if it has reduced their value.
What if the item is faulty?
Are any items excluded from 60-day returns?
Extended returns must also meet the condition requirements above. Statutory exclusions and any separate statutory rights continue to apply as set out in our full Terms & Conditions.
How do I start a return?
Please include your order number and a brief reason for the return. Do not send anything back until you have received the appropriate return instructions.
Buy with confidence: all new parts sold by Twinwoods 4x4 include at least 12 months manufacturer warranty against defects in materials and workmanship under normal use.
Some products and brands may include a longer warranty period where this is provided by the manufacturer. Where applicable, this will normally be stated on the individual product page or covered by the manufacturer’s own warranty terms.
Warranty cover applies to manufacturing defects. It does not cover misuse, incorrect fitting, competition use unless stated, contamination, modification, damage during installation, normal wear and tear, or failure caused by an unrelated vehicle fault. For certain components, proof of professional fitment may be required.
Warranty claims may require the part to be returned for inspection and/or supplier testing before the claim is accepted. Any advance replacement is discretionary.
Warranty remedies relate to the part itself, meaning repair or replacement, or refund if those are not possible. Warranty does not cover labour, removal or refitting, diagnostics, consumables, travel or other incidental costs.
This warranty is in addition to your legal rights and does not reduce those rights.
For full details, please see our Terms and Conditions.
