NGK 05–23 Chrysler 300 COP Ignition Coil – Complete Pack of 8

Restore crisp throttle response, smooth idle, and reliable power to your Chrysler 300 with this NGK 05–23 Chrysler 300 Coil-On-Plug Ignition Coil Pack (8-piece set, SKU NGK49420). Designed specifically for 2005–2023 Chrysler 300 models using a coil-on-plug (COP) system, this complete set delivers the consistent, high-energy spark your HEMI or V6 engine needs mile after mile.

Engineered for Chrysler 300 Performance and Reliability

Unlike generic “one-coil-fits-all” replacements, this NGK ignition coil pack is built around the actual ignition requirements of the Chrysler 300 platform from 2005 through 2023. The coils are tailored for the coil-on-plug design used on popular Chrysler 300 engines, with proper primary and secondary windings to support strong ignition voltage under load and at higher RPM.

Drivers often turn to this NGK coil pack when they’re experiencing:

• Intermittent or persistent misfires, especially under acceleration
• Rough idle or hesitation when pulling away from a stop
• Decreased fuel economy and sluggish throttle response
• Check engine light codes related to coil or misfire issues

Replacing all eight coils at once helps eliminate weak spots in the ignition system and reduces the chance of chasing individual failures one by one.

Why Choose NGK for Your Chrysler 300 Ignition Coils?

NGK is one of the most respected names in ignition technology, widely trusted by vehicle manufacturers and professional technicians. Their ignition coils are designed to integrate cleanly with OEM connectors, mounting points, and engine management strategies, providing:

• Consistent spark energy across all cylinders for balanced power and smoother operation
• Stable combustion that helps maintain fuel efficiency and reduce emissions
• Durable internal construction engineered to handle the heat and vibration of modern Chrysler 300 engine bays

Rather than chasing the lowest price, NGK focuses on repeatable performance and long-term reliability—qualities that matter when you rely on your Chrysler 300 for daily driving, commuting, or long highway trips.

Complete Pack of 8 – One Job, Done Right

This product is sold as a complete pack of 8 coil-on-plug ignition coils, matching the number of coils required on Chrysler 300 engines that use this COP configuration. Installing a full matched set offers several advantages over replacing a single failing coil:

• Even wear and performance – All cylinders receive coils of the same age and condition, reducing uneven running or “new vs. old” performance differences.
• Less downtime – Minimize repeat trips back under the hood as older coils start to fail over time.
• Simplified diagnostics – Once installed, you can rule out weak ignition coils as the source of future misfire issues.

Ideal Buyers and Use Cases

This NGK Chrysler 300 COP ignition coil pack is an excellent choice if you are:

• Addressing existing misfires and want a long-term fix instead of swapping one coil at a time.
• Performing a major tune-up and replacing spark plugs, boots, or other ignition parts on a higher-mileage Chrysler 300.
• Maintaining a performance-oriented build where consistent spark delivery is critical for tuned or spirited driving.
• Preventatively upgrading coils on a 2005–2023 Chrysler 300 before a long trip or after years of service.

Real-World Benefits You’ll Notice

When installed correctly with compatible spark plugs and in a mechanically sound engine, drivers typically notice:

• Smoother idle with fewer vibrations at stoplights
• Stronger, cleaner acceleration, especially under load or highway merging
• More consistent fuel economy thanks to complete combustion in each cylinder
• Reduced risk of raw fuel entering the catalytic converter due to misfires, which can help protect expensive exhaust components

Technical-Focused Design, Driver-Focused Results

While ignition coils are an electrical component, their impact is felt every time you start your car and press the accelerator. NGK designs its coil-on-plug units to provide:

• Precision-matched primary and secondary windings to generate the voltage needed to fire under lean or high-load conditions
• Quality insulation and epoxy potting to resist heat cycles, vibration, and moisture intrusion
• Direct-fit connectors and mounting geometry to match your Chrysler 300’s factory harness and brackets, helping streamline installation

Fitment and Compatibility Overview

This NGK 05–23 Chrysler 300 COP Ignition Coil – Pack of 8 is intended for Chrysler 300 models (2005–2023) that use an eight-coil, coil-on-plug ignition configuration. Always confirm engine size and ignition style for your specific model year before ordering, and check any required cross-reference to factory part numbers or UF504-style replacements if applicable.

Smart Upgrade for Long-Term Ownership

If you plan to keep your Chrysler 300 on the road for years, spending a little more up front on a trusted ignition brand makes sense. With this NGK NGK49420 coil pack, you get a matched set of eight coils designed around your vehicle’s ignition strategy, helping you:

• Reduce future ignition-related troubleshooting and parts chasing
• Maintain dependable cold starts and hot restarts
• Support the performance potential of both stock and lightly modified engines

Upgrade your 2005–2023 Chrysler 300’s ignition system with confidence and enjoy the peace of mind that comes from running a complete, NGK-engineered coil-on-plug set tailored to your vehicle.
