When it comes to getting the most out of your e-liquid, your coil choice is everything—especially if you're vaping high VG juices. High VG (vegetable glycerin) e-liquids are known for producing thicker vapor and a smoother inhale, but they also require the right hardware to perform well. Two popular contenders in the vape coil space are Innokin Zenith coils and Vaporesso GTX coils, each designed with a specific kind of vaper in mind.

So which coil wins when it comes to high VG performance? Let’s break it down.

What Are High VG E-Liquids?

High VG e-liquids typically contain more than 70% vegetable glycerin. VG is a thicker substance than PG (propylene glycol), and it’s responsible for creating dense vapor clouds and a smooth, less intense throat hit. These e-liquids are great for sub-ohm vaping but can clog or underperform with the wrong coils—especially those not designed to wick thick liquid quickly.

That’s why choosing a compatible coil is key when vaping high VG juices.

Vaporesso GTX Coils: Built for Clouds and Flavor

Vaporesso GTX coils are built for both mouth-to-lung (MTL) and direct-to-lung (DTL) vaping. But where they really shine is in sub-ohm and high-wattage vaping, making them ideal for high VG e-liquids. These coils feature mesh technology, which provides faster and more even heating. The mesh also increases the surface area, allowing for better absorption and vaporization of thick e-liquids.

GTX coil resistances range from 0.15Ω up to 1.2Ω, with the sub-ohm options (0.15Ω, 0.2Ω, and 0.3Ω) being especially popular among cloud chasers. The larger wicking holes and lower resistance make them well-suited for high VG blends. Vaporesso devices like the Target PM80 and Luxe PM40 offer full support for these coils, with adjustable wattage to dial in the perfect vape.

Innokin Zenith Coils: Flavor-Focused and Reliable

Innokin Zenith coils (also known as Z coils) are known for their excellent flavor production and smooth, cigarette-like draw. They’re typically geared toward MTL vapers and ex-smokers. The resistance range is higher—between 0.3Ω and 1.6Ω—which means they’re more optimized for lower wattage and higher PG e-liquids.

While the 0.3Ω Z coil can handle slightly thicker e-liquids, it still struggles compared to mesh coils when used with high VG juices. The wicking ports are smaller, which can lead to dry hits or coil gunking when using thicker liquids consistently. These coils are excellent for nic salts and 50/50 blends, but not the best match for max VG formulas.

Coil Design and Wicking Efficiency

When it comes to high VG juice, wicking speed and coil surface area make a big difference. Vaporesso GTX coils, with their mesh design and larger cotton openings, handle thick e-liquids efficiently. They offer faster saturation, reduced chances of dry hits, and better flavor consistency even at higher wattages.

Innokin Zenith coils, on the other hand, use traditional wire builds with tighter cotton placements. This works well for thinner e-liquids but often can’t keep up with the demands of VG-heavy juices—especially if you chain vape or crank up the wattage.

Which One Wins for High VG?

If your primary focus is vaping high VG e-liquids, Vaporesso GTX coils are the clear winner. Here’s why:

• Mesh design: Enhances vapor production and flavor in high VG conditions

• Lower resistance: Better suited for sub-ohm vaping and thick liquids

• Faster wicking: Reduces the risk of dry hits or burnt coils

• Device compatibility: Vaporesso offers multiple kits optimized for DTL and high VG vaping

Innokin Zenith coils are better reserved for vapers who prioritize mouth-to-lung hits, smoother draws, and thinner e-liquids like nic salts.

Final Thoughts

If you enjoy dense clouds and use e-liquids with high VG content, Vaporesso GTX coils will give you a more satisfying, smoother, and efficient vape. Their design supports faster wicking, stronger flavor delivery, and greater vapor output—exactly what high VG vaping demands.

Innokin Zenith coils remain excellent for MTL vaping and everyday reliability, but when it comes to high VG juice, they simply aren’t built to perform at the same level. The choice ultimately depends on your vaping style, but for high VG fans, Vaporesso has the edge.
