NGK Ignition Coil 4.6L 8 Pack Ford F150 2009 2010 Set

NGK Ignition Coil restores reliable spark delivery for your 4.6L Ford F-150, improving firing consistency and helping reduce misfires caused by a weak ignition system.

This ignition coil set is presented as an 8-pack intended for the specified application and is sold through Mishimoto, a vendor noted for its motorsports and performance-oriented components.

Function and value

The ignition coil's main role is to convert the battery's low-voltage current into the high-voltage pulse required to ignite the air/fuel mixture. Ensuring the coils are in proper working order addresses one of the four fundamental engine requirements—spark—so you can verify other upgrades or maintenance without ignition-related variables affecting performance diagnostics.

Key technical features and why they matter

• Application-specific pack size: 8 coils supplied to match the 4.6L V8 configuration, allowing complete replacement of all cylinder ignition coils in one service interval.
• Direct-replacement design: Intended as a like-for-like replacement for the factory coils on compatible Ford F-150 models, minimizing installation complexity and fitment changes.
• Restores strong spark output: Replacing weakened coils helps eliminate misfires and rough idling that result from insufficient spark energy, improving combustion stability and drivability.
• Vendor provenance — Mishimoto: Distributed by Mishimoto, aligning the product with a supplier known for performance-focused parts and aftermarket support.

Performance considerations

Using a full set of coils ensures uniform spark performance across all cylinders, which is important for balanced power delivery and consistent ignition timing. Replacing all coils together avoids mixed-condition components that can mask intermittent ignition faults during diagnostics or after engine upgrades.

Install and test each coil per factory service procedures to confirm proper electrical connections and to verify elimination of misfire codes or rough-running symptoms.
