  1. David wain (verified owner)

    Well impressed with the workmanship.improved the heater on my Land Rover by 100% best heater iv ever had in a Land Rover

  2. David (verified owner)

    Excellent product, well made, easy to fit, and it WORKS! A warm Landrover 90 at last.

  3. Charlie Mackenzie

    Very nicely made. Definitely warmer than the standard heater matrix. Was it worth 9x the price of the standard part? I think it was, because I’m keeping this Land Rover forever and I’m fed up being cold in the not-summer. Still a hell of a price though…

  4. Dave Trimble

    Sick of suffering the cold in my 110 with its puny heater I just fitted the Allisports Defender uprated heater matrix and wow! what a difference. Made my Landy a pleasure to drive in cold weather. Lovely cab temp & awesome window demisting. So impressed – got to be one of the best upgrades I’ve made in over 30yrs of Landrovering. Superb quality & finish. Well worth the cost and fitting. . If you’re thinking of buying this don’t hesitate – invest and luxuriate in the toasty comfort that this fantastic product gives – and at last an end to the constant complaints from the Mrs about would be warmer in an open top tractor.

    Thanks again for design and building the Defender matrix WOW! again.
