XYZIL 12V Ignition Coil C-624 (UC12T) — Direct-Fit Replacement for Ford Tractors, High-Output Durable Design

XYZIL 12V Ignition Coil C-624 (UC12T) is a direct-fit replacement coil engineered to restore reliable spark performance on a wide range of vintage and modern engines, including many Ford, GM and Chrysler applications.

This high-output 12V ignition coil from XYZIL is designed as a drop-in replacement for many OE and aftermarket part numbers, giving older tractors, trucks and industrial engines a dependable ignition source. Built for durability and broad compatibility, the coil works with multiple cross-reference numbers so you can match it to legacy systems without modifying wiring or mounts.

Which vehicles and part numbers does this coil replace?

The XYZIL C-624/UC12T coil cross-references a long list of original equipment numbers across Ford, GM and Chrysler families, plus various industrial and agricultural models. It fits many classic Ford tractors (including 8N and NAA chassis) and a host of GM and Chrysler part codes, making sourcing straightforward for restoration projects.

• Fits Ford legacy numbers like 1100-0544, B6A-12029-A/B and D5TE-12029-AB.
• Crosses to GM references including 383444 and several 1115xxx series codes.
• Matches many Chrysler/Jeep OEM and aftermarket IDs used in older vehicles.
• Comprehensive cross-listing reduces guesswork when replacing worn coils.

How does this ignition coil affect engine starting and performance?

By delivering a consistent high-voltage pulse to the spark plug(s), the coil helps ensure more reliable ignition events, which improves cold starts and steady idling on older engines. It won’t change engine tuning, but it restores the ignition component that often fails with age, cracking, or electrical wear.

• Delivers steady secondary voltage for reliable spark generation.
• Reduces misfires caused by weak or leaky coils.
• Direct-fit design simplifies installation—no special adapters required.
• Durable insulation and terminals resist corrosion in harsh environments.

What are the installation and wiring considerations?

Installation is typically straightforward: disconnect battery power, remove the old coil, transfer any mounting hardware if required, and reconnect the primary and secondary leads to the matching terminals. Verify polarity and terminal labeling before reconnection to prevent miswiring.

• Mounts to standard ignition coil bracket locations on compatible engines.
• Primary terminals accept original connector types; reuse existing harness where possible.
• Confirm ground and positive feed location; some setups need a ballast resistor in-line.
• Test with a multimeter or spark tester after installation for proper function.

What materials and build features improve longevity?

XYZIL uses robust housing materials and quality winding techniques to resist heat and vibration—common failure causes in automotive coils. Protective coatings and secure terminal assemblies minimize moisture intrusion and electrical leakage over time.

• High-temperature varnish on windings to limit deterioration.
• Sealed housing to reduce moisture and dirt ingress.
• Corrosion-resistant terminal studs for long-lasting connectivity.
• Engineered for repeated thermal cycles common in older engines.

Who is this for? Mechanics, restorers and DIY owners who maintain vintage tractors, classic trucks, or industrial engines will find the XYZIL 12V Ignition Coil a practical replacement choice when original coils fail or are no longer available. If you need a direct-fit coil that matches legacy part numbers and restores dependable ignition without aftermarket rewiring, this unit is tailored for those projects.
