NGK Genuine Ignition Coil U2058 (Part # 48261)

The NGK Genuine Ignition Coil U2058, identified by part number 48261, is a high‑performance ignition component engineered to deliver reliable spark generation for a wide range of Chrysler and Dodge engines. Designed with precision engineering, this coil ensures optimal combustion efficiency, improved fuel economy, and reduced emissions.

Key Design Features

• High‑Quality Materials: Constructed from premium copper windings and a robust ceramic insulator, the coil resists high temperatures and electrical stress.
• Compact Architecture: The compact form factor allows seamless integration into tight engine bay spaces without compromising airflow or maintenance access.
• Vertical Primary Connection (Oval): The primary winding is configured in a vertical oval shape, providing excellent electrical isolation and minimizing the risk of arcing.
• 4‑Pole Design: Equipped with four poles to support multi‑spark ignition systems, enhancing spark timing precision across all cylinders.
• Robust Insulation: The ceramic insulator is engineered to withstand high voltage spikes and thermal cycling, ensuring long service life.

Compatibility Overview

The U2058 coil is specifically tailored for a range of Chrysler and Dodge models. Its compatibility spans multiple engine configurations, including:

• Chrysler Voyager (Mk III, Grand Voyager IV) – 3.3L & 3.8L engines
• Dodge Caravan (Mk II, Mk III) – 3.3L & 3.8L engines
• Tacuma (Mk II)
• Other OEM models that utilize the 4609140AB or 00K04609140AC reference numbers.

Engineers and technicians can verify exact fitment by cross‑referencing the vehicle’s VIN, engine code, and the coil’s part number. The U2058 is a direct replacement for OEM coils in these models, ensuring that performance standards remain unchanged.

Installation Guidelines

1. Safety First: Disconnect the battery to prevent accidental spark or electrical shock during installation.
2. Remove Existing Coil: Carefully detach the primary and secondary leads, noting their orientation. Use a coil removal tool if necessary to avoid damage.
3. Position the New Coil: Align the vertical primary connection with the engine block’s mounting points. Ensure that the coil sits flush against the gasket surface for optimal thermal contact.
4. Reconnect Leads: Attach the primary and secondary leads exactly as they were on the original unit, maintaining polarity to preserve ignition timing.
5. Secure Fasteners: Tighten all mounting bolts to the manufacturer’s specified torque settings. Over‑tightening can crack the ceramic insulator; under‑tightening may lead to poor heat dissipation.
6. Re‑connect Battery and Test: Restore battery power, start the engine, and observe for smooth idle and consistent acceleration. A diagnostic scan tool can confirm that spark timing is within spec.

Performance Benefits

• Consistent Spark Output: The coil’s high‑quality windings produce a stable spark voltage, reducing misfires and ensuring efficient combustion.
• Improved Fuel Efficiency: By delivering precise ignition timing, the U2058 helps engines burn fuel more cleanly, lowering overall consumption.
• Reduced Emissions: Accurate spark generation leads to lower unburnt hydrocarbons and nitrogen oxides, aiding compliance with emission regulations.
• Longevity: The durable construction resists wear from high temperatures and electrical stress, extending the component’s service life beyond many aftermarket alternatives.

Maintenance Tips

While the NGK U2058 is designed for long‑term reliability, routine checks can preempt potential issues:

• Inspect lead connections annually for corrosion or looseness.
• Verify that the coil’s mounting surface remains clean and free of oil or debris.
• Use a spark tester to confirm voltage output if engine performance deteriorates.
