Collection: Aspire K3 Replacement Coils

Aspire’s Nautilus coils are available in multiple resistances across mesh and traditional builds. This variety makes it easy to tailor your vape for either MTL (mouth-to-lung) or RDTL (restricted direct-to-lung) vaping, depending on the coil you choose.

Features

Lower-resistance options such as 0.3Ω and 0.4Ω are designed for a warmer vape with increased vapour and a looser RDTL inhale. Higher-resistance options such as 1.6Ω and 1.8Ω deliver a more discreet MTL draw with a cigarette-like feel. For best results across the range, use 50/50 e-liquid or a high PG blend.
