These triple titanium wrapped rod based coils have been designed with a different housing that lacks bottom airflow holes as they are for use with the Core E-rig. The housing is missing holes as the Core only has top airflow, with the regular bottom airflow coils concentrate is pushed down through these holes creating extra mess. There is the option of the original Porous Black Ceramic or Quartz rod based coils. Fully compatible with the New Sequoia, to be used with top airflow only.
The original porous black ceramic coils can be loaded with large quantities and used to wick this up, generating large clouds either on manual heat up or with session mode. Since the quartz is not porous these should generally be used with manual heat up as they will attempt to vapourize all your concentrate very quickly so will empty in a couple of draws, this makes them generally unsuitable for session mode. We have provided this option as we prefer the flavour produced from these coils.
These coils can be cleaned by soaking them in cleaning solvent, leaving them to dry and firing them while empty to remove extra residue. Please note these replacement coils do not come with a warranty.
