My Matrix that I received is built like the proverbial Tank. It so solid and well put together that I think you could stand on it and do it no harm (no liability will taken if you do so and break it from me or Allisport). You will need to modify you heater box Matrix clamping frames but that’s no big deal. A Dremel type cutting wheel works best I found with a good set of files to tidy up at the end. The only niggley thing I have to complain about it lack of Stickers in the box to replace the ones already stuck to the Matrix, just in case you wish to paint the End Tanks and Frame of the Matrix like I have, that’s all. Other than that I’m a happy chappy, Thanks Guys. Now that was about the actual Item. As to Customer Service, I was informed when I first purchased both the Matrix and a Radiator for my TD5 that there would be a delay as they (Allisport) had just moved shop and production was not at full capacity. Ok, I can live with a small delay for top notch gear right….but not 5 months. What soured the experience for me the most was a lack of regular updates unless I poked the mountain and requested one, and even then that didn’t always get a reply. I know I got them in a bad situation with the shop swap but common guys, 5 months, really! Anyway I was going to give Allisport 3 Stars, HOWEVER they redeemed them selves by including a small sweetener with in my packages (that’s between me and Allisport) and just the other day I sent a request through if I could have some stickers to go onto my freshly painted items and I received a resounding “YES” and “how many would I like” and I have already been told “sent in the mail’, SO 4 Stars it is (just in case they get lost in the mail). 😀

Thank you for your review and I apologise your order was tangled up in our workshop expansion, which took a lot longer than anticipated! Thank you for your patience.
Mr Mark E Moss –
I ordered one of these as the existing one gave out about as much heat as a door draft, so followed a few reviews and took the plunge. All I can say is… I am so glad I did. Firstly the build quality is amazing, secondly the heat output is noticeable hotter. OK like all defenders the Td5 engine takes time to heat up. So can take time for the heat to come through but this is no fault of the matrix, but when the engine is at running temperature the heat output is amazing. So bring on the winter, I’m ready.

This Allisport heater actually produces heat. A BIG improvement.

Another top quality product from AlliSport !
Made very very well !
Fitted perfectly once the top and bottom cover plates had been cut to suit .
The Heater is actually lovely and hot now !
Would highly recommend these !
My only complaint would be that there was not enough stickers in the box , haha !

Hi sorry have not fitted it to the car yet as it is still under going work but I will say it’s very well made
George Darrow –
The craftsmanship put into this heater core is so superior to the OEM or any other attempt its not even funny. The communication with AlliSport throughout the inquiry and ordering process was exactly what you’d expect from a custom fab upgraded parts supplier, simply perfect and dead on with all their recommendations. This heater core provides heat like I’ve never experienced in my D110 and actually keeps the wife and kids very happy even when its -2º and blizzardy outside. The simple fab work needed to fit this item in is so simple and yields such a huge benefit for actual heat that works in freezing climates. Thank you for the solid custom parts and excellent customer support. Cheers!!!!

fantastic fabrication quality
Perryn Edwards –
Quality item, well designed and fabricated, going back in the Landy today and looking forward to the extra heat. How about fabricating the top and bottom plates as an add-on?
christian nordanger (verified owner) –
I am happy with this. Very good heating
Nigel Cass –
Superb quality product. Designed to work. Top quality, durable materials; precision fabrication – clearly made with real care. Allisport were very helpful in ensuring I ordered the correct version. Packed and delivered very securely. Highly recommended.

I have dealt with Alisport on several occasions over my years of Land Rover ownership and keep returning as the craftsmanship within there products is second to none even with my latest purchase which is the upgraded Defender heater matrix ( fitted but not used in anger yet due to ongoing refurbishment) the quality is outstanding!!! And yes if I upgrade anything else I will again return to them for it
Nigel Snow –
Finally got round to installing a Allisport heater matrix in my 300 TDi and wow!
Unlike the factory original, the Allisport matrix deserves the word heater in its name, a night to day improvement. 5 minutes into the test drive I had to turn the fan down from the old ‘all winter’ max setting and 5 minutes after that I had to turn the heat level down to the mid point! No longer will I need to wear a heavy coat when driving in winter or shout quite so loudly over the flat out fan noise.
And its a thing of beauty with fab looking weld quality, shame its buried in the heater box.
Overall all, it really is that good.
