Innokin Prism T18E Replacement Coils

Innokin Prism T18E Replacement Coils

The T18E is the TPD-compliant version of Innokin's long-running Endura pen, and this is the coil that keeps it running. The Innokin Prism T18E coil is an MTL head wicked with Japanese organic cotton, built for a smooth, tight, cigarette-style draw.

It comes in two resistances, a 1.5ohm and a higher 1.7ohm, so you can dial in how tight and cool you want the vape. It uses Innokin's No-Spill Coil Swap system, so changing it is quick and mess-free, and it is sized for the 2ml TPD Endura tanks.

Sold as a pack of 5, which covers most vapers for a month or two. If your T18E still does the job and just needs a fresh coil, these Vape Coils are the genuine replacement for any MTL Vape Kit in the TPD Endura range.

Why vapers choose this:

• TPD-compliant Innokin coil with Japanese organic cotton delivers clean, consistent MTL flavour and helps maintain flavour quality throughout the coil's lifespan.

• Two resistances, a 1.5ohm for a tight cigarette-style draw and a 1.7ohm for something even tighter and cooler.

• No-Spill Coil Swap means you change the coil in seconds without draining the tank.

• Pack of five. Roughly a month or two of daily use.

• Fits the whole TPD Endura family, so one coil covers several kits.

Innokin Prism T18E Replacement Coils Features

No-Spill Coil Replacement

Most tanks make you empty the liquid before you can reach the coil. Innokin's No-Spill Coil Swap system does not. You unscrew the base collar, the internal chimney seals the tank, and you simply pull the old coil out and push the fresh one in without juice going everywhere. It is a small piece of engineering that makes a genuinely annoying job painless. Anyone who has changed a coil over a sink will appreciate it.

Japanese Organic Cotton

The wicking here is Japanese organic cotton, and it matters more than it sounds. Cheaper coils use lower-grade wicking that can carry a faint off-taste on the first few draws and burn out sooner. The organic cotton in these coils saturates evenly through its multiple wicking ports and gives a clean flavour from the first fill. Pairs best with a 50/50 E-Liquid or a higher-PG blend.

Built for a Tight MTL Draw

At 1.5ohm, this coil sits firmly in mouth-to-lung territory. That means a tight, controlled draw that feels close to a cigarette, which is exactly what most people stepping off tobacco are after. It suits mid to higher-strength nicotine well, so browse the Nic Salts Range or a freebase 10ml E-Liquid at 12mg to 18mg for the best match.

Low-Wattage Coil Design

These coils are designed for the low-power output of the Endura pens, so they barely touch the battery. If you carry a T18E to work and vape through the day, the modest power draw means you are not scrambling for a charger by lunchtime. This is coil engineering built around efficiency, and it still holds up.

TPD-Compliant Coil Size

The T18E coil is the shorter, TPD-compliant evolution of the original design. Shrinking the coil down left more room for e-liquid in the 2ml tank while keeping the tight, warm MTL draw the Endura is known for. It is a small change that made the pen legal for the UK market without losing what made it work.

Innokin Prism T18E Coils Resistance Options

Two genuine resistances to choose from, each giving a slightly different draw.

How to Set Up the Innokin Prism T18E Replacement Coils

A quick swap thanks to the no-spill base. A couple of minutes, start to finish.

1. Unscrew the bottom metal collar of your Endura tank. (The tank can remain filled, as the chimney seals the liquid inside).

2. Pull the old coil straight out of the tank. It releases without threading.

3. Prime the new coil by dripping three to four drops of e-liquid directly into the exposed cotton wicking holes on the side of the coil.

4. Drop the fresh coil into the tank. Important: Ensure the two flat edges on the base of the coil align perfectly with the matching flat edges on the tank housing so it sits completely flush.

5. Screw the bottom metal collar back onto the tank securely.

6. Stand the tank upright for a full five to ten minutes so the cotton saturates completely before you fire it. Skipping this will instantly scorch a new coil.

7. Start vaping at the tank's standard wattage and let the flavour settle over the first few draws.

What's in the Innokin Prism T18E Coils Box

Five genuine Innokin Prism T18E coils in your chosen resistance, either 1.5ohm or 1.7ohm. That is the lot. No tank, no e-liquid, no battery. Just the coils.

If your Endura tank itself is worn out rather than the coil, you will find replacement tanks and hardware over in the MTL Tanks section.

The Coil for Innokin's TPD Endura Tanks

These 3-hole coils are made exclusively for Innokin's TPD-compliant, 2ml Prism tanks. That covers the Endura T18E and its sibling, the T22E. It also fits the modern T18 II and the T18 II Mini, along with the T18-X and the T22 Pro. Thanks to some clever cross-compatibility by Innokin, they also drop straight into the Endura M18 pod kit for vapers who prefer the classic T18E draw.

What they will not fit: the older, longer pre-TPD tanks. The legacy Endura T18 and the original T22 use a taller coil and are not compatible with the T18E head. If you are unsure which tank you own, the TPD versions hold 2ml and are the ones sold in the UK. Browse the full Innokin Vapes range for the matching tanks and kits.

About Innokin

Innokin has been a fixture of UK vaping since the early days, and the Endura T18 is one of the reasons why. Launched as a simple, reliable MTL pen for new vapers, it became a genuine landmark starter kit, and the T18E is its TPD-compliant successor, reworked to meet UK regulations with a 2ml tank.

The Prism coil is the part that has kept the line going for the best part of a decade. Innokin's focus has always been on approachable, dependable hardware rather than chasing cloud-chasing trends, and the T18E coil is a neat example: low wattage, clean flavour, and a design that simply works. It remains the genuine replacement for a kit that is still in daily use across the country.

Stock Up and Save

At daily MTL use, one coil lasts a week or two, sometimes longer with lighter habits. Picking up a couple of packs at once covers you for months and means you are never stuck with a burnt coil and no spare.

Every order from Pirate Vapes ships same-day when placed before 4 pm, sleeved to protect the coils in transit. All stock is TPD compliant, checkout is age-verified, and sales are strictly over-18s only.

Conclusion

The Prism T18E is a niche coil in 2026, but it serves a real purpose. If you own a TPD Endura tank and it still does the job, a fresh five-pack of genuine Innokin coils, in either the 1.5ohm or the tighter 1.7ohm, is the cheapest, simplest way to keep it running. 

Japanese organic cotton, a tight MTL draw, and the no-spill swap system make coil changes painless. Browse more Vape Accessories, or head back to Pirate Vapes to see the full range.

FAQs

Which tanks do the Prism T18E coils fit?

Innokin's 2ml TPD Endura tanks. That covers the T18E and T22E, plus the T18 II and its Mini version. The T18-X and T22 Pro take it too, as does the M18 pod kit. They do not fit the older, longer pre-TPD T18 or T22 tanks.

What resistance are the Prism T18E coils?

They come in two: a 1.5ohm and a 1.7ohm. The 1.5ohm is the standard, familiar draw, while the 1.7ohm runs tighter and cooler and stretches the battery a little further.

What e-liquid works best with the Prism T18E coils?

50/50 VG/PG or a higher-PG blend. These are MTL coils built for a tight draw, so thick high-VG juice will not wick properly and risks dry hits.

How long does each Prism T18E coil last?

Usually one to three weeks with daily use. Sweeter, darker liquids shorten that as residue builds on the cotton faster.

Can I use nic salts with the Prism T18E coils?

Yes. The tight MTL draw and low wattage suit nic salts well at 10mg or 20mg. Freebase at 12mg to 18mg also works nicely.

How many Prism T18E coils come in a pack?

Five Prism T18E coils come in one pack, with the resistance of your choice.
