Innokin iSub Plex 3D Coils

Innokin iSub Plex 3D Coils

A single 0.35ohm build rated for 30-55W, the Innokin iSub Plex 3D coils are the direct replacement for the iSub-B Sub-Ohm Tank and the wider iSub tank series. Each coil pairs a stainless steel body with a Kanthal 3D mesh heating element cut with micro-grooves for extra surface area, wicked with a mix of organic cotton and wood pulp.

Pack of five. Built for sub-ohm, direct-to-lung vaping with high VG e-liquid, this is the pack to reach for when your iSub tank starts tasting burnt or the clouds thin out.

Why vapers choose the iSub Plex 3D coils:

• A wider surface area from the micro-groove mesh design means more of the coil actually touches your e-liquid, which is where the flavour and vapour improvement over older iSub coils comes from.

• Wood pulp wicking alongside organic cotton for a faster, more even soak that resists dry hits.

• Runs comfortably from 30W right through to 55W, so it suits both a gentler daily vape and a more powerful mod.

• Stainless steel body.

• A pack of five keeps you stocked for a good stretch, since sub-ohm coils under regular use don't last as long as MTL coils.

Innokin iSub Plex 3D Coils Features

0.35Ω Coil for 30–55W

Rather than juggling several ohm options, Innokin built this coil around a single 0.35ohm rating covering 30-55W. That's a genuinely wide window for one coil, and it means less guesswork over which variant fits your setup. Just fit it and dial your mod in.

Mesh for Longer Coil Life

A flat mesh sheet spreads heat more evenly than a wrapped wire coil, so there's less risk of one hot spot burning through your wicking material before the rest of the coil has done its job. That even heat is a big part of why Plex3D coils tend to run cleaner for longer than the older iSub coils they replaced.

Micro-Grooved Mesh for Better Flavour

The grooves running across the mesh aren't just texture. They increase the coil's usable surface area, which is what drives the improvement in flavour and vapour production over a standard flat mesh sheet. More surface in contact with your High VG E-Liquids, more flavour reaching you.

Fast Heat-Up and Cooling

Because the mesh has low thermal mass, it heats up quickly once you fire your mod, and cools back down just as fast between draws. That responsiveness is part of what keeps the coil's lifespan up. A coil that isn't sitting hot between puffs simply wears out slower.

Wood Pulp Wicking for High-VG E-Liquid

Cotton alone can struggle to keep pace with thicker high-VG liquid at higher wattages. Blending in wood pulp speeds up how quickly liquid moves through the wick, which matters most right at the top of this coil's 55W ceiling.

Innokin iSub Plex 3D Coils Wattages

There's only one resistance here, so the choice isn't between ohm values; it's about where in the 30-55W range you settle.

How to Set Up the Innokin iSub Plex 3D Coils

A straightforward change once you've got the tank apart.

1. Unscrew the bottom cap of your iSub tank to expose the coil chamber.

2. Remove the spent coil from the base.

3. Drip a small amount of e-liquid onto the exposed mesh of the new coil before fitting it.

4. Push the fresh coil firmly into the base until fully seated.

5. Reassemble the tank and fill it, then leave it standing for six to eight minutes so the wood pulp and cotton fully soak through before your first vape.

6. Start around 30W and work up toward your preferred wattage.

What's in the Innokin iSub Plex 3D Coils Box

Each pack holds five iSub Plex 3D coils in their original sealed packaging. The iSub-B tank, mod and e-liquid are sold separately, so if you need the tank itself, check the Sub-Ohm Tanks range.

Built for the iSub Series, Not Innokin's Other Coil Families

These coils are designed for the iSub-B Sub-Ohm Tank and share a coil base with the wider Innokin iSub series. Not the Zenith. Not the Ajax. Not the Scion or Plex tanks, which use their own separate coil systems entirely. If your Innokin tank isn't from the iSub line, this pack won't fit, so it's worth checking the model printed on your tank before ordering.

They're built for DTL sub-ohm vaping. A 60% VG or higher e-liquid suits the wicking far better than a thinner 50/50 mix, and lower nicotine strengths within the UK's 20mg/ml legal cap tend to work best at this kind of wattage.

About Innokin

Innokin's iSub range has gone through six generations, and the Plex3D coil was the update that brought mesh technology into that lineup properly. Earlier iSub coils used standard wrapped wire, which meant more inconsistent heating and a shorter working life under sub-ohm wattages.

Swapping in a micro-grooved mesh design solved both problems at once, giving the range a coil that heats faster, cools faster, and holds its flavour output for longer. It's a solid example of Innokin refining an existing platform rather than starting from scratch. Browse the full Innokin Vapes range for tanks and kits from the same brand.

Stock Up and Save

A worn sub-ohm coil doesn't fail gently; it goes from good flavour to a burnt taste within a single tank refill. Keeping a spare pack of Innokin iSub Plex 3D coils on hand means that never catches you out mid-session.

Conclusion

The Innokin iSub Plex 3D coils give iSub-B owners a direct, genuine replacement with a wide 30-55W range from a single 0.35ohm build.

The mesh design, wood pulp wicking and stainless steel body make it a dependable choice for daily sub-ohm vaping, and a pack of five covers you for a good while.

FAQs

Which tanks do these coils fit?

The Innokin iSub-B Sub-Ohm Tank and other tanks in the iSub series. They won't fit the Zenith, Ajax, Scion or Plex tanks, which use different coil systems.

What wattage should I run them at?

Anywhere from 30W to 55W. Lower in that range favours flavour and coil lifespan; higher favours denser vapour.

Do these coils need priming first?

Yes. Add a few drops of e-liquid to the mesh before fitting, then let the filled tank sit for six to eight minutes before your first vape.

What e-liquid works best with this coil?

A 60% VG or higher blend. Thinner 50/50 liquids don't wick as well at sub-ohm wattages and can lead to a dry, harsh hit.

How long does one coil typically last?

This varies with wattage and e-liquid, so we can't give a fixed figure. A burnt taste or noticeably weaker vapour is your cue to swap.

Can I use these on any mod?

Any mod capable of reaching the coil's rated wattage will work, provided it's paired with an iSub-B or compatible iSub tank. The coil doesn't fit tanks outside that range, regardless of the mod.
