MAS Ignition Coils Pack DG508 & Motorcraft SP479 Spark Plugs

In this review of the MAS set of 10 ignition coils DG508 paired with 10 Motorcraft Platinum spark plugs SP479, the bottom line is practical: this kit is for owners of compatible Ford V10 6.8L vehicles who need a full-cylinder ignition refresh with clear OEM cross-reference numbers. The reviewer found the combined pack delivers straightforward fitment for the listed Model years and engine, simplifies parts purchasing by including coils and plugs for all 10 cylinders, and can restore smooth idle and consistent firing when the correct fitment is verified before ordering.

Key Features

• Complete 10-cylinder kit: Includes ten MAS ignition coils DG508 and ten Motorcraft Platinum SP479 spark plugs so a single purchase services the entire V10 ignition system.
• OEM cross references: The kit lists many compatible OEM numbers, which helps confirm fitment against dealer parts lists and repair manuals.
• Vehicle fitment list: Specifically called out fitment with 1998-2008 E350 and 1999-2008 E450 and several Super Duty models, reducing guesswork for owners of those years.
• One year warranty: A one year warranty gives basic protection against early failures and provides buyer reassurance for a critical drivetrain part.
• Plug choice: The included Motorcraft Platinum SP479 plugs are intended to work with the ignition coils and the V10 6.8L combustion characteristics.

Who It's For

This kit suits owners and small-fleet operators of Ford vehicles with the 6.8L V10 engine that appear on the fitment list: E350, E450, Econoline Super Duty, Excursion, F250/F350/F450/F550 Super Duty models and the 2004 F53 motorhome chassis. It is especially useful for anyone who prefers to replace all coils and plugs at once to eliminate intermittent misfires and achieve uniform performance across ten cylinders.

Buyers who should look elsewhere include those who do not have one of the listed model years or who are uncertain about their OEM part numbers; the listing emphasizes verifying compatibility before purchase. Also, if a customer requires extended coverage beyond one year or OEM-branded coils only, a factory dealer source may be preferable.
