Replacement Vape Coils: Get Your Flavour, Throat Hit, and Draw Back
Your coil does more work than any other part of your setup. It heats your e-liquid, shapes your flavour, determines how your draw feels, and ultimately defines whether vaping feels great or just average. When it starts to wear out, everything else follows.
This is where you find the right replacement, filtered by type, brand, and resistance, so you don't have to guess whether it will fit.
How to Know Which Coil You Actually Need
First of all, check your tank or pod system and identify the coil series it uses. This is usually stamped on the side of your current coil or listed in your device manual. Coils are not universal. For example, a Vaporesso GTX coil will not fit an Aspire tank, and a SMOK TFV16 coil will not work in a Uwell Caliburn.
Getting this right first saves time and avoids unnecessary returns.
Once you know the correct series, the next step is choosing the right resistance, which is where things become more important.
MTL vs Sub-Ohm: The Choice That Changes Everything
This is often where new vapers make mistakes, so it is worth understanding properly.
MTL Coils (Mouth-to-Lung)
MTL coils run above 1.0 ohm, typically between 1.0Ω and 1.8Ω. They provide a draw similar to a cigarette. You first pull vapour into your mouth, then inhale.
As a result, the draw feels tighter, vapour production is lower, and flavour is clean and precise rather than heavy.
These coils are ideal for nicotine salts. They work at lower wattages, usually between 10W and 20W, and deliver smooth nicotine at higher strengths such as 20mg. Therefore, if you are switching from smoking, this is the best place to start.
With proper use, MTL coils typically last one to three weeks. However, sweet e-liquids can shorten their lifespan.
Sub-Ohm Coils (Direct-to-Lung)
Sub-ohm coils run below 1.0 ohm, usually between 0.15Ω and 0.6Ω. They are designed for direct-to-lung vaping, where vapour is inhaled straight into the lungs.
This produces warmer vapour, larger clouds, and fuller flavour. As a result, they are ideal for experienced users.
These coils require high VG e-liquid, usually 70 percent or more, and higher wattages ranging from 30W to 80W or beyond.
However, coil life is shorter. Heavy users may need to replace them every three to seven days.
Most sub-ohm users prefer 3mg or 6mg freebase nicotine since the vapour production is higher.
Mesh Coils
Mesh coils use a flat metal sheet instead of a traditional wire. Because of the increased surface area, they heat more evenly and quickly.
As a result, you get better flavour, faster ramp-up time, and longer coil life compared to standard coils.
Today, most modern coils use mesh technology. Therefore, if you have the option between standard and mesh, mesh is usually the better choice, especially for fruit and menthol flavours.
Ceramic Coils
Ceramic coils are less common but still useful in certain situations. They heat more gradually and maintain a consistent temperature.
Because of this, they produce a smoother and cooler vape. In addition, they can last longer when using sweet or high-VG e-liquids.
However, they may not deliver the same sharp flavour as mesh coils, particularly for fruit flavours. Still, they are worth trying if coil lifespan is a concern.
Rebuildable Coils (RDA, RTA, RDTA)
Rebuildable coils are designed for advanced users. Instead of buying pre-made coils, you build your own using wire and cotton.
While this requires some knowledge of resistance and wicking, it offers better performance and lower long-term cost.
If you are new to rebuilding, starting with pre-made coil builds or kits can make the process easier.
Coil Resistance and What It Means
Resistance directly affects heat, vapour production, and nicotine delivery. Therefore, choosing the right level is essential.
Resistance
Style
Wattage
E-Liquid
Nicotine
1.0Ω – 1.8Ω
MTL
10–20W
50/50
10–20mg salts
0.6Ω – 1.0Ω
RDL
20–35W
60/40 or 70/30
6–12mg
0.2Ω – 0.6Ω
Sub-ohm
35–60W
70% VG+
3–6mg

If your throat hit feels weak, it is usually due to incorrect resistance rather than nicotine strength.
Flavour and Coil Pairing
Different coils perform better with different flavour types.
Fruit and menthol liquids work best with mesh coils and higher VG ratios because they enhance sharpness and clarity.
On the other hand, tobacco and dessert flavours often perform better in MTL setups. The tighter airflow creates a richer and more concentrated taste.
Also, keep in mind that very sweet e-liquids can damage coils faster. Therefore, regular coil changes are necessary.
Always prime your coil before use. Add a few drops of e-liquid, fill your tank, and wait five minutes before vaping.
When Your Coil Needs Replacing
Coils don't announce when they're done; they just gradually make vaping worse. The signs to watch for:
A persistent burnt taste that doesn't clear after adjusting the wattage is the clearest sign. So is a noticeable drop in flavour intensity, even if there's no burning, the cotton is saturated, and the coil surface is gunked up. Gurgling sounds during a draw usually mean e-liquid is pooling through a flooded or damaged coil. If your e-liquid has turned noticeably dark in the tank, that's caramelised sweetener — the coil is almost certainly on its way out, and your device needs a replacement coil.
Brands We Stock and What They're Known For
These are the coil ranges you'll find at AJ Super Store, and a quick word on what each brand tends to do well.
Aspire coils, particularly the Nautilus and BP ranges, are some of the best MTL coils going. Consistently clean flavour, reliable lifespan, and wide compatibility across their pod and tank systems. If you're on an Aspire device, stick with Aspire coils.
OXVA coils for the Xlim series are excellent performers for restricted DTL and MTL vapers. The 0.4Ω and 0.6Ω options are especially good for nic salts if you want slightly more airflow than a traditional MTL.
Vaporesso coils GTX and GTpunch above their price point consistently. The mesh options in the GTX range produce exceptional fruit flavour, and the coils last well even with moderately sweetened e-liquids.
Uwell coils are the benchmark for pod systems. The 1.0Ω and 1.2Ω options for the G and G2 are reliable, flavourful, and genuinely last as long as they claim, usually two to three weeks with normal use.
SMOK coils have a wide range spanning everything from high-power sub-ohm tanks to pod systems. Build quality varies across the range, but the RPM mesh coils in particular are solid performers.
GeekVape coils for the Aegis and Z series are built for durability. They run slightly warmer than some alternatives, which suits people who want a warmer vape but means max VG e-liquid is important to prevent dry hits.
Innokin coils, especially for the Zenith series, are a good pick for MTL vapers who want reliable, long-lasting coils. The Zenith 0.48Ω is one of the best restricted-draw coils at the price.
Voopoo Coils PnP and ITO cover a huge range from tight MTL to full sub-ohm and are compatible across most of the Drag and Find series. The 0.8Ω PnP-VM6 is a reliable all-rounder.
FreeMax mesh coils, particularly for the Maxus and Fireluke series, are excellent if you're chasing flavour at higher wattages. The tea fibre and mesh X coil materials genuinely outperform standard mesh in longevity.
UK Compliance and Authenticity
All coils at AJ Super Store are authentic and sourced from trusted distributors. They meet UK TPD regulations and safety standards.
Using counterfeit coils can be dangerous, especially at higher wattages. Therefore, always buy from reliable sources.
What to Buy Alongside Your Coils
A clean tank improves performance. So, it is worth rinsing your tank before installing a new coil.
If coils burn out quickly, check your e-liquid sweetness and VG ratio.
For those interested in rebuildables, coil wire and cotton are good additions to your setup.
