In this review the MAS Set of 8 Ignition Coil DG508 with MOTORCRAFT Spark Plug SP479 is evaluated for drivers who need a full ignition refresh on Ford 5.4L V8 engines. The bottom line: this kit is aimed at owners of Crown Victoria, Expedition, F-150, F-250, Mustang, Lincoln, Mercury and Explorer models who want an economical, OE standard replacement package that is straightforward to install and restores reliable spark delivery. The most compelling reason to buy is the complete set of eight coils plus spark plugs provided together, which simplifies parts sourcing and fitment when the correct application is confirmed.

Key Features

• Complete kit: Includes a set of eight MAS ignition coils and MOTORCRAFT SP479 spark plugs so all cylinder ignition components are replaced at once for consistent performance.
• OE standard construction: Coils are built to meet or exceed OE specifications under strict quality control for dependable ignition output.
• High energy output: Each coil is designed for the specific application to deliver the necessary high voltage for stable combustion in 5.4L V8 engines.
• Heat resistant boots: The coil-on-plug boots use a high heat resistant compound to withstand thermal stress and improve long term durability.
• Interchangeable part coverage: Replaces multiple reference numbers such as DG508, DG457, DG472, DG491 and several OEM equivalents to ease identification when compatibility is verified.

Who It's For

This kit is best for owners and DIY mechanics who have confirmed compatibility via the fitment list and need to replace all ignition coils and spark plugs on a Ford 5.4L V8 in one go, restoring consistent firing and simplifying maintenance. It suits fleet technicians or enthusiasts who prefer to swap the entire ignition set rather than changing coils one at a time.

It is not ideal for buyers who have not checked the year/make/model fitment or who expect guaranteed genuine manufacturer spark plugs in every box, since customer reports show mixed experiences with plug sourcing. Those seeking extended-lifespan premium plugs or individual coil replacement only should consider other options.
