12V Alternator Canister Ignition Coil with Internal Resistor Compatible With All Coils That for Resistor #383444 383449 B6A-12029 Compatible With Ford Tractors 2000 3000 4000 5000 NAA600

The CNPAPC Ignition Coil RUC15CRS is designed for 12V systems with resistor or resistor wire. Featuring an internal resistor, it regulates current flow to protect ignition components and reduce overheating. Built with durable, heat- and vibration-resistant materials, this coil ensures reliable performance and long service life. With consistent voltage output, it improves starting, minimizes misfires, and enhances overall engine efficiency. Compact canister design (6.3 × 3.9 × 2.8 in, 1.33 lbs) with OEM-style connections allows for quick and easy installation.

• Built-In Resistor Design for Plug-&-Play: This ignition coil features an internal resistor, so you don’t need an external resistor or resistor wire harness. Perfect for 12V systems with resistor, wire/distributor ignition
• Universal Fit for 12 Volt Distributor Engines: Compact canister style (6.3 × 3.9 × 2.8 in) makes it easy to install in a wide range of older vehicles or upgraded ignition systems
• OE Replacement Compatibility: Part No. RUC15CRS, Manufactured to replace legacy coil part RUC15CRS. Ideal as a cost-effective, high-quality upgrade for any distributor-based 12 V vehicle with a resistor-wire ignition system
• Durable Construction: Built from premium materials to resist heat, vibration, and corrosion, ensuring long-term reliability in classic cars, hot-rods, restored trucks and 12 V conversions
• Enhanced Ignition Output: Optimised winding and internal resistor help deliver consistent high-voltage spark, reducing misfires, improving throttle response, and ensuring cleaner starts
