Uwell Crown IV Vape Coils

Uwell Crown IV Vape Coils 

Three resistance options, one tank, no threads to fuss with. The Uwell Crown IV coils come in a pack of four and are built exclusively for the Crown 4 Sub-Ohm Tank, covering everything from smooth 60-70W daily vaping to full 70-80W cloud output.

Every coil in the range uses organic cotton wicking paired with either a dual SS904L stainless steel build or a double helix mesh design, and all three pull straight out with a plug-and-pull fit rather than a threaded base. If your Crown 4 tank is tasting burnt or running dry, this is the direct Uwell Coils replacement.

Why vapers choose the Crown IV coils:

• Three distinct resistance options to choose from, letting you dial in either dense vapour or crisp flavour clarity.

• Organic cotton wicking for cleaner flavour from the first pull.

• Self-cleaning core that catches excess e-liquid instead of leaving it pooling around the base of the tank.

• No threads to strip. Plug-and-pull installation.

• Corrosion-resistant SS904L stainless steel, which is the same grade Uwell has used across the dual-coil side of the Crown range since it was introduced, holding up well under daily high-wattage use.

Uwell Crown IV Coils Features

Two Coil Types for Different Vapes

The range covers two different builds. The 0.20ohm and 0.40ohm coils are dual SS904L stainless steel, aimed at vapers who want more vapour and a slightly warmer output at higher wattage. The 0.23ohm is a FeCrAl UN2 mesh coil built for flavour clarity over raw cloud size. Having distinct wire and mesh builds available lets you match the coil directly to your preferred wattage and e-liquid.

Easy Plug-Fit Replacement

These do not screw in. The Crown 4 coil base is a plug-and-pull fit: press the coil into the base until it seats, and pull it straight out when it is spent. No cross-threading, no overtightening, no coil stuck at an angle. It is one of the simpler swaps on the market, honestly, and it takes seconds once you have done it once.

Double Helix Mesh for Even Heating

The 0.23ohm UN2 coil uses a double helix mesh structure rather than a wrapped wire. Heat spreads more evenly across the surface, which cuts down on dry hits and gives a rounder, more consistent flavour through the session. Pair it with High VG E-Liquids for the best results.

Self-Cleaning Design

Uwell built a self-cleaning chamber into the base of every Crown IV coil. Excess e-liquid that would normally pool and leak gets pulled into a condensation holder instead, ready to be vaporised on the next draw. Less mess in the tank, less wiped-up e-liquid on your desk.

Pro-FOCS for Better Flavour

Uwell's Pro Flavour Optimisation Core System routes intake air through the coil twice before it reaches you. That extra pass pulls more flavour out of the vaporised e-liquid on every draw. It is a small mechanical tweak, but it is one of the reasons the Crown range has stuck around this long.

Uwell Crown IV Coils Resistance Options

Three options sit in the resistance picker for this pack, and the right one comes down to how much power your device puts out and whether you are chasing flavour or vapour.

How to Set Up the Uwell Crown IV Coils

No threads means no risk of cross-threading a new coil. It's a short job either way.

1. Unscrew the bottom airflow base from the tank.

2. Pull the old coil straight out of the base. No twisting needed.

3. Drip a small amount of e-liquid directly onto the mesh or cotton ports of the fresh coil before fitting it.

4. Press the new coil firmly into the base until it clicks into place.

5. Rebuild the tank and fill it, then give the coil three to five minutes to sit before your first vape so the cotton has time to fully saturate.

6. Start at the lower end of the coil's rated wattage and work upward until the flavour and vapour feel right.

What's in the Uwell Crown IV Coils Box

Each pack contains four replacement coils in your chosen resistance, sealed in their original packaging.

The Crown 4 Sub-Ohm Tank, mod and e-liquid are not included. This listing is coils only, so if you need the tank itself or a device to pair it with, check the Sub-Ohm Tanks range separately.

Made Exclusively for the Crown IV Tank

These coils fit the Uwell Crown IV (Crown 4) Sub-Ohm Tank only. Not the Crown 3. Not the Crown 5. Not the Crown D. Each generation changed the coil base design, so check the model printed on your tank before ordering.

They're built for DTL sub-ohm vaping with higher-VG e-liquid. A 70/30 blend suits the wicking ports better than 50/50, and lower nicotine strengths under the UK's 20mg/ml legal cap tend to suit sub-ohm output best.

About Uwell

Uwell built its reputation on the Crown line, and the self-cleaning core here is one of the clearer signs of how far it's come. Earlier Crown tanks needed regular wiping to stop e-liquid pooling around the coil base.

The Crown 4's condensation chamber deals with that automatically, a genuinely practical fix rather than a marketing add-on. Combined with Pro-FOCS airflow, Uwell has kept the Crown range focused on flavour and reliability. Browse the wider Uwell Vape range for tanks, kits and pods from the same brand.

Stock Up and Save

Coils wear out. Keeping a spare pack of Uwell Crown IV coils in the drawer means a burnt taste never turns into a day without your tank.

Pirate Vapes ships every order same-day when it's placed before 4 pm, and checkout is age-verified, with all products sold TPD-compliant, for over-18s only.

Conclusion

The Uwell Crown IV coils give Crown 4 owners three genuine resistance options in one pack, from a balanced 0.40ohm daily coil to a mesh-built 0.23ohm for flavour chasers. Plug-and-pull fitting and the self-cleaning core keep maintenance low, and the SS904L build holds up well under regular sub-ohm use.

If your Crown 4 is due for a change, this pack covers it. Browse more Vape Accessories or head back to Pirate Vapes for the rest of the range.

FAQs

Which tank do these coils fit?

The Uwell Crown IV (Crown 4) Sub-Ohm Tank only. They will not fit the Crown 3, Crown 5 or Crown D, as each uses a different coil base.

What wattage should I run them at?

Start at the low end of the coil's rated range and adjust upward. The 0.40ohm and 0.23ohm both sit at 60-70W, while the 0.20ohm runs hotter at 70-80W.

Do I need to prime them before use?

Yes. Add a few drops of e-liquid to the coil's ports before fitting it, then let the tank sit for three to five minutes once filled so the cotton fully saturates before your first vape.

Which resistance should a beginner pick?

The 0.40ohm is the easiest starting point. It's balanced, doesn't run through e-liquid too fast, and doesn't need a high-wattage mod to perform well.

How often will I need to replace them?

Most coils last 1 to 2 weeks depending on your wattage, e-liquid sweetness, and daily use. Swap the coil as soon as you notice reduced vapour or a dull, burnt taste.

Can I use these with any mod?

Any mod capable of hitting the coil's rated wattage will work, as long as it's paired with the Crown 4 tank itself. The coils don't fit other tanks regardless of the mod.
