RFX Engine Plugs are engineered from 7075‑T6 aluminum, providing a robust yet lightweight foundation for high‑performance ignition systems. Each plug features an 8 mm or 6 mm hex key head for secure torque application, and the body is finished with a color anodized coating that resists corrosion and enhances durability.
The plugs incorporate a lightweight hollow design that reduces mass without compromising structural integrity. They are compatible with OEM O‑rings, ensuring a reliable seal and consistent performance across a range of engine configurations.
