Description

The 04E905110K Ignition Coil by Hudson generates the high-voltage energy required to ignite the compressed air-fuel mixture inside the cylinder. This direct ignition coil installs directly over the spark plug to deliver rapid and consistent electrical discharge. Consequently, a properly functioning coil promotes smooth engine starting, stable idling, and responsive throttle performance.

Engineered to meet stringent automotive standards, this Hudson replacement coil provides reliable service under demanding driving conditions. Furthermore, its durable construction ensures dependable electrical insulation against high engine-bay operating temperatures.

Why the 04E905110K Ignition Coil Matters

Modern compact engines rely on precise ignition timing and strong spark output to achieve optimal fuel efficiency and low tailpipe emissions. Over time, however, continuous heat cycles and high electrical loads degrade internal windings and primary insulation. Consequently, an aged coil may produce intermittent or weak spark output.

A failing ignition coil can lead to severe engine misfires, rough acceleration, and increased fuel consumption. Furthermore, unburned fuel resulting from incomplete combustion can enter the exhaust system and damage the catalytic converter. Therefore, replacing a compromised 04E905110K Ignition Coil promptly protects critical emissions equipment and restores peak engine performance.

Signs of Ignition Coil Failure

Inspect your ignition system if you notice any of these common failure symptoms:

  • An illuminated check engine light with diagnostic trouble codes for cylinder misfires.

  • Noticeable engine hesitation, stumbling, or jerking during acceleration.

  • A rough, erratic, or vibrating idle while the vehicle is stationary.

  • Reduced overall engine power output and sluggish throttle response.

  • Decreased fuel economy during normal operating conditions.

  • Difficulty starting or prolonged cranking times when starting the engine.

  • Visible hairline cracks, thermal damage, or carbon tracking along the coil body.

  • Corroded, loose, or oil-fouled electrical connector pins.
