DG513/DG500 Ignition Coil Pack 6PCS & SP493 Spark Plugs - Reliable Fit

In this review of the DG513/DG500 ignition coil pack set with SP493 spark plugs, the bottom line is simple: this kit is for owners of 3.0L Ford, Mazda and Mercury models who need a complete, budget-friendly ignition refresh that fits straight into the factory locations. The reviewer found the set straightforward to install, compatible with the listed vehicles, and engineered for high heat and impact resistance, making it a practical choice when original coils show misfire symptoms or aging. It delivers dependable functionality and clear value for routine replacement intervals.

Key Features

• Direct OEM fit: The kit lists multiple OEM cross numbers so it matches factory mounting and connector locations for the supported 3.0L vehicles.
• Complete set: Six ignition coils and matching SP493 spark plugs cover all cylinders for a full ignition service in one purchase.
• High temperature resistance: Coils are described as high-temperature and impact resistant, which helps maintain performance under engine heat.
• Trivalent plated plugs: The spark plugs use trivalent metal plating designed to improve corrosion resistance and reliable spark delivery.
• Manufacturing standards: Made in TS16949 certified facilities with 100% function and leakage testing to reduce early failures out of the box.
• Warranty coverage: A 1 year or 50,000 km warranty provides short-term protection against manufacturing defects.

Who It's For

This kit is best for DIY mechanics and independent shops working on Ford Escape 3.0L (2001-2008), Five Hundred/Freestyle 3.0L (2005-2007), Taurus 3.0L (1999-2004), Mazda Tribute 3.0L (2001-2011), and Mercury Mariner/Montego/Sable 3.0L models listed in the fitment. It suits anyone replacing worn coils and plugs together to restore smooth idle and eliminate misfires.

Drivers who require OEM-branded parts or a longer factory-backed warranty may want to look elsewhere, and those with non-3.0L engines should verify fitment carefully since this kit is specific to 3.0L applications only.

Pros & Cons

Pros

• Replaces all ignition coils and plugs at once for consistent ignition performance across cylinders.
• Multiple OEM cross numbers increase the chance of correct fitment with factory components.
• Quality control and testing reduce the risk of early leakage or failure.
• Good value compared with buying individual coils and plugs separately.

Cons

• Not branded as OEM by a vehicle manufacturer, and some buyers note mixed feelings about replacement value versus original factory parts.
• Warranty is limited to 1 year or 50,000 km, which is shorter than some extended aftermarket guarantees.
