In this review the MAS Ignition Coils DG508 bundled with Motorcraft OEM Spark Plugs SP413 are assessed for owners of Ford V8 4.6L vehicles who need a full ignition service kit. The bottom line: this pack is best for DIY mechanics and repair shops seeking an economical, OE-standard replacement that aims to match original equipment performance while simplifying installation by providing eight coils and plugs together. It is particularly useful when replacing a full bank of cylinders or addressing intermittent misfire issues.

Key Features

• OE standard construction: Each ignition coil is built to meet or exceed original equipment specifications for dependable ignition performance.
• Complete pack of eight: The bundle includes eight coils and compatible spark plugs, making full-bank replacement straightforward and time saving.
• High heat resistance: The coil-on-plug boots use a heat resistant compound to withstand underhood heat stress and last longer in demanding conditions.
• Easy installation: Coils are designed for direct replacement on the specified applications, reducing installation time for experienced installers.
• Motorcraft OEM plugs: The included SP413 spark plugs follow OEM standards so they match the coils and intended engine performance.

Who It's For

This kit is intended for owners of Ford F-150 and Mustang models with the V8 4.6L engine who need to replace all ignition coils and plugs at once, or for shops performing maintenance on multiple cylinders. It suits someone comfortable verifying fitment details and comparing parts visually before purchase.

Those with uncommon engine variants, such as specific Mustang GT 3V configurations, or buyers who cannot confirm fitment from the listing should look elsewhere or consult a dealer, since compatibility confusion has been reported and correct selection relies on the fitment list.
