Aspire Nautilus X U-Tech Coils 1.8Ω – 5 Pack (Kanthal)

Innovative airflow. Smooth flavour. Built for the perfect mouth-to-lung vape.

The Aspire Nautilus X 1.8Ω Replacement Coils are designed exclusively for the Nautilus X tank, using U-Tech coil technology to create a unique and efficient airflow path. Unlike traditional coil designs, vapor flows through a U-shaped chamber, passing through the Kanthal coil twice before inhalation — enhancing flavour, warmth, and throat hit.

With a recommended wattage range of 12W to 16W, these coils are ideal for mouth-to-lung (MTL) vapers who prefer nicotine salts or 50/50 freebase e-liquids. Their high-resistance build promotes longer battery life, making them an excellent choice for compact pod mods and starter kits.
