MAS Set of 8 Red Ignition Coils Pack Curved Boot Compatible with Ford

In this review the MAS set of 8 curved boot ignition coils is evaluated for drivers who need a full replacement pack for Ford, Lincoln and Mercury V8 engines. The bottom line: this eight-pack is for owners of older 4.6L and 5.4L V8 vehicles who want an economical way to restore consistent spark and smoother idle. The reviewer found the coils offer good electrical resistance and a strong spark from the plugs, and that replacing a full bank of coils often cured rough idle and misfire issues on compatible E, F and Expedition family models.

Key Features

• High material quality: Built to provide high electrical resistance, these coils help deliver a strong, consistent spark to the plugs for reliable combustion.
• Corrosion resistance: Components are designed to resist corrosion and abrasion, which supports longer service life in under-hood conditions.
• Vehicle fitment breadth: Compatible with many Ford, Lincoln and Mercury models including E150, E250, E350, F150 and Crown Victoria, making this pack useful for several common V8 applications.
• Complete eight-pack: Sold as a set of 8 so technicians and DIYers can replace an entire engine bank at once, reducing diagnostic guesswork and mismatched aging parts.
• Known part cross references: Cross-compatible with many OEM and aftermarket part numbers such as DG508, DG491, FD503 and others for easier sourcing and comparison.

Who It's For

This pack is best for owners of 4.6L and 5.4L V8 Ford, Lincoln and Mercury vehicles from the late 1990s through early 2010s who need to replace multiple coils at once. It suits fleet, restoration or maintenance work where matching new coils across all cylinders is preferred to spot replacement.

Those who should look elsewhere include owners of 2004-and-newer F150 trucks with the 5.4L V8 noted as incompatible in the product description, and anyone who requires factory OEM-branded coils or direct dealer support for warranty claims beyond the one year limited warranty.

Pros & Cons

Pros

• Good value for an eight-pack that restores smooth engine operation on compatible V8s.
• Durable construction that resists corrosion and abrasion under the hood.
• Strong spark performance reported by users, improving idle and drivability.
• Wide model compatibility and multiple cross-reference part numbers for fit verification.

Cons

• Fitment opinions vary among customers, so careful verification against vehicle year and engine is required.
• Not compatible with certain model years of the F150 5.4L V8; double-check before purchase.

Frequently Asked Questions

Are these coils compatible with my 2003 F150 5.4L?
They are compatible with many 1997-2008 F150 5.4L applications, but confirm the part cross references and your exact engine code to be sure.

Do these come with a warranty?
Yes, the coils include a one year limited warranty; contact the seller for warranty service details.

Will replacing all eight coils fix a misfire?
Replacing all eight can eliminate issues caused by weak or failing coils and is recommended when multiple cylinders show problems, though diagnosis should confirm coil failure first.
