These genuine UWELL Crown 4 Coils for the Crown 4 Tank are the finest coils available for this tank.

The Crown 4 replacement coils  feature UWELL’s patented self-cleaning technology which collects excess ejuice in a condensation chamber near the bottom of the coil and vaporizes it. This allows for less frequent cleaning of your Crown 4 Tank.

These coils also have UWELL’s patented Pro Flavor Core Optimization System (or Pro-FOCS). Pro-FOCS recycles the air through the coil two times during intake in order to saturate each puff with as much flavor as possible.

The dual helix design in these Crown 4 coils are modeled after luxury watches and made out of high quality stainless steel, providing improved taste, vapor, and coil longevity. The FeCrAl UN2 coils feature a honeycombed mesh design, enabling the coil to heat instantly and evenly.

UWELL’s wicking material is made up of 100% Organic Cotton Fiber. These attributes combined with the airflow and self-cleaning abilities of the Crown IV series of coils, affords them the ability to extend their lifespan over previous coils in the Crown family.
