When it comes to mesh coil innovation, Innokin iSub Plex3D Coils and Innokin Ajax Plex3D Coils stand out for their advanced heating performance, enhanced flavour delivery, and extended lifespan.
Both coil ranges use Plex3D mesh technology combined with a wood pulp and organic cotton wicking blend, but they are designed for different devices and power levels.
If you’re unsure which Innokin coil suits your tank or vaping style, this complete breakdown will help you decide.
What Is Plex3D Mesh Technology?
Plex3D coils use an advanced mesh heating element featuring:
- Micro-groove surface design
- Increased heating surface area
- Faster ramp-up time
- Lower thermal mass
- More efficient cooling
The result?
- Faster e-liquid absorption
- Reduced dry hits
- More consistent flavour
- Longer coil lifespan
Unlike traditional wire coils, Plex3D mesh heats evenly and cools quickly, reducing stress on the cotton and improving durability.

Innokin Ajax Plex3D Coils (0.16Ω & 0.35Ω)
Ajax Plex3D coils are engineered for higher wattage vaping and larger cloud production.
Available Options
0.35Ω
30–55W
Balanced sub-ohm performance
0.16Ω
50–80W
High-power, intense cloud production
Compatibility
Ajax Tank
MVP5 Kit
These coils are designed for vapers who prefer more aggressive sub-ohm setups with stronger vapour density.
Technology & Wicking Material
Both coil ranges use:
Advanced 3D mesh heating
Micro-groove surface design
Organic cotton + wood pulp blend
Why Wood Pulp + Cotton?
This combination improves:
Capillary action
Faster e-liquid movement
Cleaner flavour reproduction
Reduced dry hits
The mesh design increases surface contact with e-liquid, delivering sharper flavour and smoother vapour.
Key Differences Explained
1. Compatibility
iSub Plex3D coils fit iSub-series tanks.
Ajax Plex3D coils fit Ajax Tank and MVP5 Kit only.
They are NOT interchangeable.
Always check your tank model before purchasing.
2. Power Output
iSub Plex3D: Mid-range power (35–55W)
Ajax 0.16Ω: High power (up to 80W)
Ajax 0.35Ω: Flexible mid-range option
If you prefer high-wattage cloud chasing, Ajax 0.16Ω is the stronger choice.
3. Vaping Experience
Choose iSub Plex3D if you want:
Balanced flavour and vapour
Moderate wattage use
Longer battery efficiency
Choose Ajax Plex3D if you want:
Larger cloud production
Higher wattage vaping
More intense sub-ohm performance
How to Prime Plex3D Coils Properly
To extend coil life:
- Add a few drops of e-liquid directly onto the cotton.
- Install the coil into the tank.
- Fill the tank and wait 5–10 minutes.
- Start at the lower wattage range.
- Increase power gradually.
Proper priming prevents dry hits and improves longevity.
Key Takeaways
- Both use advanced 3D mesh technology
- Both feature wood pulp + organic cotton wicking
- Ajax coils handle higher wattage (up to 80W)
- iSub coils provide balanced mid-wattage performance
- They are NOT interchangeable
Frequently Asked Questions
Q: Are iSub and Ajax Plex3D coils interchangeable?
A: No. Each is designed specifically for its compatible tank range.
Q: Which coil produces the biggest clouds?
A: The Ajax 0.16Ω coil (50–80W) produces the largest clouds.
Q: Which coil is best for flavour?
A: Both deliver excellent flavour, but iSub 0.35Ω offers a smoother, balanced profile.
Q: What e-liquid works best?
A: High-VG e-liquids (70/30) are recommended for optimal performance.
Q: Do Plex3D coils last longer than regular coils?
A: Yes. Their lower thermal mass and micro-groove mesh design help extend lifespan.
Final Verdict
Both Innokin iSub Plex3D and Ajax Plex3D coils deliver outstanding mesh performance with superior wicking and flavour.
Your choice ultimately depends on:
- Your tank compatibility
- Preferred wattage range
- Desired cloud production
If you want balanced sub-ohm vaping at moderate wattage, choose iSub Plex3D 0.35Ω.
If you prefer higher wattage and massive clouds, go with Ajax Plex3D 0.16Ω.
Either way, Plex3D technology guarantees faster heating, cleaner flavour, and longer-lasting coils.
