Autolite High Thread Pro plugs are expertly crafted to deliver exceptional performance for Ford 3V engines. Featuring a fine-wire platinum center electrode with an extra-long special projection, these plugs ensure a more focused ignition and extended service life. The proprietary design enhances heat management, fouling resistance, and dielectric strength, while the ground strap improves heat transfer compared to standard J-gap plugs. The thread position above the cylinder head seating creates a compressive seal, boosting durability and power. With a nickel-plated shell, these plugs offer superior corrosion resistance, ensuring long-lasting reliability. Designed for performance-grade applications, they are the ideal choice for maintaining optimal engine efficiency and power.
