The surprisingly warm early autumn weather means that Mazda MX-5 – or kitcars based on same – owners can go on enjoying their cars for longer this year, but when it’s unseasonably warm, the last thing you want is more heat coming through the firewall, floor or transmission tunnel.

That’s where the latest offering from DEI comes in. The DEI Thermal & Acoustic Kit for the 1990-2005 MX-5 insulates the interior from radiating heat but when the weather does change it will keep the interior warmer so you can continue driving long into the winter months.

Annoying sounds like road, tyre and exhaust noise are also reduced thanks to the sound-absorbing qualities of the material. Overall, this kit creates a more comfortable internal temperature and quieter experience which improves the stereo performance and makes for effortless conversation.

The kit replaces the factory padding and insulation with DEI’s unique UC Lite™ material which is CNC pre-cut for an easy fit and quick installation. Unlike conventional soundproofing material, DEI’s UC Lite™ is lightweight and has negligible effect on the car’s performance.
