Matrix Tank Coils: Compatibility And Performance

Matrix tank coils shape how a sub-ohm tank tastes and performs. When a coil wears out, flavor fades, vapor weakens and burnt hits start to creep in.

Replacing a worn Matrix coil restores flavor and vapor and helps prevent burnt hits and leaks. Knowing which coil fits your tank, and when to change it, saves e-liquid and frustration.

This guide covers which coils carry the Matrix name, their resistance options, and how to install and prime them.

Key Takeaways

"Matrix" coils are tank-specific, so check that a coil is listed for your tank before buying.
Replacing worn coils keeps flavor clean and reduces burnt hits.
Good priming and sensible wattage can extend the life of each coil.

Matrix Tank Coils (Replacement) Overview

The best-documented Matrix coils are Innokin's Plex3D Matrix coils for the Ajax tank, which comes in Innokin's Proton Mini Ajax and MVP5 Ajax kits. Other sellers have also used the Matrix name for their own sub-ohm tanks and coils.

Key Features and Design of Matrix Replacement Coils

Innokin describes the Ajax tank's coils as "next generation Plex3D Matrix coils." Plex3D is Innokin's name for its machined mesh-style heating element, which spreads heat over a wide area of cotton.

A wide heating surface helps the coil wick evenly and reduces dry hits. These coils are built for direct-lung vaping in a matrix tank setup at fairly high wattage.

Other brands' Matrix coils, such as dual vertical coil heads made for a separate Matrix sub-ohm tank, are a different product. They are not interchangeable with Innokin Ajax coils.

Variants and Resistance Options

Resistance affects vapor warmth, airflow needs and nicotine delivery. Innokin's Proton Mini Ajax product page lists these Ajax coil options:

Coil Type	Resistance	Recommended Wattage (Innokin)
Ajax Plex3D Matrix Coil	0.16 ohm	50-80W
Ajax Plex3D Coil	0.35 ohm	30-55W

Some retailers have also listed 0.2 ohm and 0.6 ohm "Matrix" coils for a different brand's Matrix sub-ohm tank. We could not confirm those from a manufacturer page, so check the packaging for your tank.

Lower resistance sub-ohm coils need more wattage and produce more vapor and heat. Nicotine salt e-liquids are usually meant for low-wattage, higher-resistance pod systems, not 50-80W sub-ohm coils.

Installation and Replacement Process

Empty the tank or turn it upside down, remove the base, and pull or unscrew the old coil, depending on your tank's design. Fit the new coil firmly so it makes good electrical contact.

Prime the coil before use. Wet the cotton through the juice ports with a few drops of e-liquid, fill the tank, and wait five to ten minutes so the cotton fully saturates.

Start at the low end of the coil's recommended wattage and increase slowly. Replace the coil when flavor turns muted or burnt even with a full tank.

Performance Factors: Flavor and Vapor Production

Flavor depends on the coil design, resistance and airflow. Mesh-style coils such as Innokin's Plex3D heat evenly, which many users find gives clear flavor.

Vapor output rises with lower resistance, higher wattage and more open airflow. A 0.16 ohm coil at 50-80W produces far more vapor than a mouth-to-lung coil.

More vapor also means more nicotine per puff at the same e-liquid strength. High-wattage sub-ohm users usually choose low nicotine strengths, such as 3mg or 6mg, to avoid taking in more nicotine than they intend. The FDA notes that nicotine is highly addictive.
