The Innokin iSub-B Plex 3D Replacement Coils iscompatible with a range of tanks and kits including the iSub-B vape tank by Innokin. The Plex 3D Coils features a specially designed mesh coil for increased surface area resulting in increased flavour and vapor production. With a 0.35 Ohm resistance they are best suited for DTL sub ohm vaping and we recommend using high 70%+ VG E-Liquids with this coil for best results.
