This BTC (Bottom Turbine Coil) replacement coil fits Spartan and Spartan Mini (Trojan) clearomizers. Horizon has updated the BDC (Bottom Dual Coil) coils to BTC (Bottom Turbine Coil) coils. This new and improved coil is made with organic cotton and the vertical coil gives a much fuller vape.

Since I vape a cinnamon juice, these coils work great without having to use a sub ohm tank and coils
