Innokin Zenith 'Z' Coils Pack of 5: The Basics

Innokin Zenith 'Z' Coils Pack of 5 is a pack of five replacement coil heads priced at £8.95, sold as a consumable for compatible Innokin hardware. There is no device in this pack, no e-liquid and no battery. What you get are the small replaceable units that sit inside a tank, hold the wicking material, and turn liquid into vapour when the device fires.

Coils are the part of a refillable setup that people underestimate. The device is a one off purchase, the liquid is an obvious ongoing cost, and coils sit quietly between the two as the component that determines whether the whole thing tastes good or tastes like a bonfire. Nothing else in a vape setup has as much influence over the day to day experience for as little money.

Innokin is a long established hardware name and has 4 products listed in the Innokin range here, most of which are consumables rather than kits. That reflects how hardware brands actually earn their keep: someone buys one tank and then buys coils for it repeatedly for years.

The rest of this page covers what to check before ordering, how to install a coil so it lasts, what shortens coil life, and how to tell when one is finished. If you have arrived because your current coil has started tasting off, skip to the sections on priming and on what kills coils early.

Why Coils Are Consumables, Not Spare Parts

A spare part is something you replace when it breaks. A consumable is something you replace on schedule because using it wears it out. Coils are firmly the second thing, and framing them correctly changes how you buy them.

Inside every coil head is a heating element wrapped around or through an absorbent wick. Liquid soaks the wick, the element heats it, vapour comes off, more liquid soaks in. That cycle runs thousands of times. Over those cycles the wick discolours and stiffens, residue from sweeteners and colourings bakes onto the element, and the flavour drifts from clean to muddy to burnt. No maintenance reverses that. It is the normal end of a normal life.

This is precisely why coils are sold in packs of five rather than singly. A five pack is not a bulk discount gimmick, it is a supply of the thing you will definitely need again, bought at the point where buying is convenient rather than urgent. The alternative is discovering at 9pm on a Sunday that your last coil has died.

If you are unsure what fits your device, the broader replacement coil listing groups the common families together, and the accessories section covers the other consumables such as seals, glass and pods that eventually need replacing too.

Checking Compatibility Before You Order

Coils are not universal. A coil head is engineered for a specific tank or family of tanks, and the wrong one will either not thread in at all or will seat badly and leak. Three checks avoid almost every mistake.

Check the family name. Coils are sold by the hardware they belong to, and the name on the pack should match the name on your tank. Manufacturers reuse letters and numbers across generations, so read the whole name rather than recognising one word of it.

Check the resistance. Every coil head has its resistance printed on the side, usually alongside a recommended power range. Within one family there are typically several resistances aimed at different styles of vaping, and picking the wrong one gives you a working coil that feels nothing like what you wanted. Match it to what your device supports and to the resistance you have been using happily.

Check the liquid. Thicker liquids need coils with generous wicking channels. Thinner liquids suit tighter ones and can flood a coil built for something heavier. If you mostly run bottled shortfills, worth glancing at the ratio printed on the bottle before choosing between resistances in a family. The shortfill e-liquid listing is where most of those larger bottles sit.

When in doubt, keep the packaging from the coil currently in your device and buy the same thing again. That sounds obvious and it is still the most reliable method there is.

Priming: The Five Minutes That Decide Everything

The single most common cause of a coil that tastes burnt on its first day is an installation that took thirty seconds instead of five minutes. Cotton that has not fully absorbed liquid will scorch the instant power hits it, and a scorched wick never recovers. You cannot un-burn cotton.

The routine is simple.

• Take the new coil out and find the wicking ports, the openings in the side of the coil body where cotton is visible.
• Drip liquid directly into each port until the cotton darkens and stops absorbing. A few drops per port is normally enough.
• Put a drop or two down the centre of the coil as well.
• Fit the coil, assemble the tank, and fill it.
• Leave the whole thing standing upright for at least five minutes. Ten is better with thicker liquid.
• Take three or four draws without firing the device, which pulls liquid through the wick under suction.
• Start vaping at a power setting below your normal one and work up over the first tank.

That last point matters as much as the soaking. Coils bed in. Hitting a fresh one at full power immediately is how people get a coil that tastes slightly off for its entire life rather than only at the end.

What Shortens Coil Life

Coil lifespan varies enormously between users, and the variation is almost entirely down to a handful of habits rather than luck.

Sweeteners. Heavily sweetened liquids, particularly dessert and candy blends, leave caramelised residue on the element. This is the biggest single factor. If you live on sweet liquid, expect shorter coil life and buy accordingly. It is not a fault in the coil.

Dark and heavily coloured liquids. The same principle applies to anything with a lot of colouring in it. More stuff that is not water or nicotine means more stuff to bake on.

Running the tank dry. The wick starves before the tank looks empty, because the last few millilitres sit below the feed ports. Refilling at a third full rather than at the last drop is the easiest life extension going.

Chain vaping. Draw after draw with no pause means the wick cannot resaturate between hits. The result is a series of small dry hits that gradually cook the cotton.

Excess power. Every coil has a range printed on it. Sitting at the top of that range constantly will get you more vapour and fewer days.

Leaving liquid sitting. A tank left full for weeks lets liquid steep against the cotton, which dulls the flavour of the first tank after a break.

Spotting a Coil That Has Reached the End

Coils rarely fail suddenly. They fade, and most people put up with a dying coil for several days longer than they should, blaming the liquid.

The first sign is usually loss of definition. A blend that had distinct notes becomes generic and flat. Nothing tastes wrong exactly, it just tastes less like anything. The second sign is a faint scorched edge at the back of the throat, particularly on longer draws. The third is a change in vapour: less of it, or a thinner, drier quality to it.

Visual checks help confirm. Take the coil out and look at the wicking ports. Fresh cotton is white or off white. A finished coil shows cotton that has gone brown, sometimes with a hard darkened crust around the element. That crust is what you have been tasting.

Two other symptoms are worth separating out. Gurgling and liquid in the mouth usually mean flooding rather than wear, which is often solved by a firmer seating or a gentler draw rather than a new coil. A sudden strongly burnt taste with no gradual decline usually means the wick dried out, which a fresh coil fixes but which will happen again if the underlying habit does not change.

Once you know the signs, change it early. A worn coil ruins liquid you have already paid for, so waiting is a false economy.

The Rest of the Innokin Consumables Line

With only four Innokin products listed, the range is easy to hold in your head, and each one exists for different hardware.

Innokin Jem Coils Pack of 5 at £11.95 is the dearest of the coil packs listed here, aimed at a different device family. Innokin Prism S T20S Replacement Coils Pack of 5 at £9.95 sits between the two on price and again serves its own tank. And Innokin VCAP Replacement Pods at £5.95 covers pod based hardware rather than threaded coil tanks, which is a different maintenance model entirely: you replace the whole pod instead of a coil inside it.

The reason to know the shape of the range is straightforward. Coil packs from the same brand are not interchangeable, and the price differences between them reflect different products rather than different quality tiers. Buying the cheapest Innokin coil pack because it is the cheapest will simply leave you with coils that do not fit anything you own.

If you own more than one device, which plenty of people do once they have a pocket setup and a home setup, it is worth keeping a labelled box with the right consumables for each. Sorting that out once saves a lot of confusion later.

Cost Per Coil, Dispatch and Adults Only

At £8.95 for five, this pack works out at £1.79 per coil. Whether that is good value depends entirely on how long each one lasts you, which as covered above is mostly determined by your liquid and your habits. Someone running plain fruit liquid at moderate power gets a very different cost per week from someone running heavy dessert blends flat out, from the identical pack.

The useful comparison is not coil against coil, it is your total running cost against the alternative. Refillable hardware plus consumables is generally the cheaper long term route for regular use, and the coils are a real part of that sum rather than an afterthought. Work them into your monthly figure honestly.

Free UK delivery applies once your basket goes over £20, so a single coil pack will not reach it on its own. Coils and liquid are the natural pairing, since you tend to need both at the same time anyway. Orders placed before 4pm on a working day are dispatched that day and tracking is emailed when the parcel is collected. Everything we sell is genuine stock through legitimate UK supply, which matters with coils because counterfeit heads are a real problem in the market and they perform badly.

Vaping products are sold to adults aged 18+ only. Age is confirmed at checkout and the courier may ask for identification. These coils contain no nicotine, but they are part of a vaping setup and are intended for adult vapers and for adult smokers who have switched to vaping. Keep spare coils out of reach of children, and let a used coil cool fully before handling it.

Delivery, returns and buying with confidence

The buying side is straightforward. Weekday orders placed before 4pm are dispatched the same day, and UK delivery is free once your basket reaches £20.00. Tracked options are shown at checkout.

We cannot resell an opened consumable, so opened items are outside the returns policy. Anything faulty or wrongly sent is our problem to fix, not yours. Sales are strictly 18+ and every order is age-verified before dispatch.

Nicotine is an addictive substance and these products are intended for adults who already smoke or vape.

Buying this as a first purchase

First time buying this sort of product? The decisions that matter are simpler than the shelf suggests.

1. Format. A prefilled pod is the no-mess option. Bottled e-liquid costs less per millilitre if you do not mind refilling.
2. Strength. This comes in 0mg. Heavier former smokers usually start high and step down.
3. Flavour. Pick two from different families rather than committing to one.

Beyond that, it is down to taste rather than technique. The deals page is the cheapest way to try more than one at a time.

Looking after it, and what goes wrong

A short list of habits prevents nearly every common problem.

• Prime before the first draw. Click the pod in and leave it a minute. Drawing on a dry wick is what causes that scorched first hit.
• Keep it cool and upright. Heat thins liquid and pushes it through seals, which is why a hot car is the usual cause of a leak.
• Muted flavour is often you, not it. Palate fatigue is common on a single flavour, and rotating to a second profile resets it.
• Store away from children and pets, and recycle spent hardware rather than binning it loose.

Do those four things and most of the usual problems never appear.

Building a rotation instead of buying one thing

The single most common mistake is buying five of the same flavour. Palate fatigue sets in faster than people expect. A profile you loved on day one can taste flat by day ten, not because the product changed but because your palate stopped noticing it.

Rotation solves it entirely. Keep two profiles from genuinely different families on the go, and alternate between them. Something sweet paired with something sharp, or a fruit paired with a menthol, resets the palate each time you switch. Two flavours in rotation will each last noticeably longer than either would alone.

The wider category is the place to find a contrasting profile if this line has no siblings.

Multibuy offers make this cheap to do, and they can be mixed across flavours.

Nicotine strength, explained properly

Strength is the decision people get wrong most often, and it is the one that most affects whether switching sticks. This listing offers 0mg. UK law caps nicotine at 20mg per ml, so nothing sold legally here goes higher, and the honest question is how far below that ceiling you should sit.

The instinct is to go low, and it usually backfires. If a strength does not satisfy, you compensate by vaping more often, which costs more and rarely feels better. A heavier former smoker typically starts at the top of the range and steps down over weeks or months once the habit has settled. Someone who smoked lightly, or who has already been vaping a while, is usually comfortable in the middle.

Throat feel matters too. Higher strengths give a firmer hit at the back of the throat, which many people switching from cigarettes actively want, and which others find harsh. Nicotine salts are smoother than freebase at the same number, which is why bar-style liquids sit at 20mg without feeling like it. If you are unsure, buy one of each rather than committing to five of the wrong one. 10mg options and 20mg options are browsable separately.
