Vaporesso GTi Replacement Coils

Vaporesso GTi Replacement Coils
GTi is the sub-ohm coil platform for Vaporesso's iTank range. Every resistance sits under 1 ohm, so these are lung and restricted lung coils on higher VG e-liquid, with no mouth to lung option in the family. Five GTi coils are included in each pack.
The coil pushes into the base of the tank and pulls straight out, so a change takes seconds. Which resistance to pick depends on the draw you want.
Vaporesso build GTi on their COREX heating technology, with what they call the Morph-Mesh structure and COREX cotton. Vaporesso split their vape coils across two platforms, GTi and GTX, and the two do not swap over in either direction.
Key Features of Vaporesso GTi Coils
- Four resistances: 0.15, 0.2, 0.4 and 0.5 ohm
- Two dual mesh options: 0.2 and 0.4 ohm, which Vaporesso build with a dual-layer mesh structure
- Sub-ohm only: lung and restricted lung, with no mouth to lung coil in the range
- Push fit: into the base of the tank, nothing to screw
- Coil life: about one to two weeks in our experience
- Five per pack: every resistance is sold as a five-pack
- Not GTX: Vaporesso state the two platforms are not interchangeable in either direction

GTi Coil Compatibility: Which iTank Models and Kits They Fit
More than most people think, because GTi replacement coils cover the whole iTank range rather than a single kit.
| Kit or tank | Notes |
| Armour Ultra | Ships with the iTank T and two GTi coils |
| Armour OCTA | Also ships with the iTank T and GTi coils |
| Armour Max and Armour S | Both listed by Vaporesso on the GTi platform |
| GEN 200 | Ships with the iTank 2 |
| iTank T | Takes all four GTi resistances |
| iTank and iTank 2 | The original tank and the second version, both GTi |
If your Vaporesso takes an iTank, it takes GTi. If it takes an XROS pod, a GTX pod or an xTank, you need GTX or COREX coils instead.
Which Resistance to Pick
These are Vaporesso's published wattages, both the range and the figure they mark as best.
| Coil | Wattage | Best | Draw | E-liquid |
| 0.15 ohm mesh | 75W to 90W | 85W | Sub-ohm lung | High VG |
| 0.2 ohm mesh | 60W to 75W | 65W | Lung | High VG |
| 0.2 ohm dual mesh | 60W to 75W | 65W | Lung | High VG |
| 0.4 ohm mesh | 50W to 60W | 55W | Restricted lung | 70/30 |
| 0.4 ohm dual mesh | 50W to 60W | 55W | Restricted lung | 70/30 |
| 0.5 ohm mesh | 30W to 40W | 35W | Restricted lung | 70/30 |
The 0.2 ohm GTi is the everyday choice in the range and the one most people buy. The 0.15 ohm is the warmest and thirstiest, best on a max VG shortfill. The 0.5 ohm is the coolest and the most forgiving, and it lasts longest between changes.
Mesh vs. Dual Mesh Coils
Two of the resistances come both ways. Vaporesso describe the dual mesh as a dual-layer mesh structure, and say it extends coil life by 30% from their own lab testing, though they do not name what that is measured against.
At the same resistance and the same wattage, the dual mesh gives more vapour. Pick it if you want more cloud without dropping the resistance.

GTi or GTX: Which Do You Need
This is the question worth getting right before you order, because the two coil types do not swap over and Vaporesso say so outright.
| GTi Coils | GTX Coils | |
| Goes in | iTank, iTank 2, iTank T | Luxe XR and Armour G pods, xTank, xTank T |
| Kits | Armour Ultra, Armour OCTA, Armour Max and S, GEN 200 | Armour G and GS, Luxe X2, X3, XR Max, XR Max 2, GTX One Pro |
| Resistances | 0.15 to 0.5 ohm | 0.15 to 1.2 ohm |
| Draw | Lung and restricted lung only | Lung through to mouth to lung |
If your kit takes a pod rather than a tank, you want a GTX coil. Neither platform fits the XROS kits, which use a pod with the coil sealed inside and no coil to replace at all.

How Long a GTi Coil Lasts
Vaporesso do not give a coil life in refills or days for GTi coils. In our experience, a GTi coil lasts about one to two weeks for a daily lung vaper, and less on very sweet e-liquid.
Our guide to how long Vaporesso pods and coils last covers what wears a coil out.
The signs a GTi coil is done:
- A burnt or flat taste.
- Thinner vapour than the coil gave when it was new.
Sweet dessert flavours caramelise on the mesh and shorten coil life, so those go sooner than fruit or menthol. Priming a new coil and letting it soak for five minutes before the first draw is what gets the most out of it.
