Carbon Fiber is the latest standard of choice for OEM auto heated seats used by many new car manufacturers. The benefit of carbon fiber that it is thread like and requires very little voltage to produce a lot of heat. No one uses copper based elements anymore (used ten years ago), they are outdated and have high chance of breaking down, burn your seat covers, and catch on fire. Our carbon fiber elements can be cut and holes can be made in the middle to allow you to keep the shape of your channels. This is something our competitors don't have, which makes a good reason why you should try out our product.
