ignition coil DG508 & Spark Plug SP413 Compatible with Ford F-150 F250

In this review of the Bravex ignition coil DG508 with SP413 spark plugs the bottom line is simple: this kit targets owners who want a durable, higher-output ignition upgrade for 4.6L V8 Ford applications. The reviewer found the kit delivers noticeable ignition energy and long service life thanks to a super high conductive coil and iridium spark plug electrodes. Installers seeking improved throttle response and a reliable replacement that claims a long mileage guarantee will appreciate this pairing; the review focuses on fit, materials, and real-world durability observations.

Key Features

• Racing-grade coil: The coil is engineered for professional racing application and is built to deliver stronger, more consistent sparks under load.
• 15% more energy: Bravex states the coils produce 15% more energy than OE units, which can improve combustion stability and throttle response.
• Iridium spark plugs: SP413 plugs use an iridium center electrode and nickel-alloy terrain electrodes for long life and steady torque delivery.
• High-quality materials: The coil uses Germany-imported Elektrisoal copper wire and German Huntsman epoxy for improved conductivity and dielectric performance.
• Long warranty: The kit is sold with a 5 year warranty on coils and a claimed 100,000 mile coil guarantee, offering peace of mind for long-term ownership.
• OEM compatibility: Designed to replace a broad list of OEM numbers, easing selection for many Ford V8 engines and related models.

Who It's For

This kit is aimed at DIY mechanics and performance-minded owners of Ford F-150, F-250, Mustang and other V8 4.6L platforms who want a direct-replacement coil pack and plug set with improved spark energy and longer service life. It suits drivers who want a measurable upgrade over worn OE coils and plugs without changing ignition timing or other engine systems.

It is less appropriate for owners who need a one-off cheap short-term fix or who require an exact OEM-branded part for dealer warranty work; those users should consider factory replacement parts or consult a dealer for warranty-covered service.

Pros & Cons

Pros

• Higher energy output that can improve combustion and throttle response compared with many stock coils.
• Durable construction using high-conductivity copper wire and premium epoxy for better heat and dielectric performance.
• Iridium center electrode plugs that are rated for extended life and consistent torque delivery.

Cons

• Claimed performance gains depend on vehicle condition; a worn fuel or ignition system elsewhere can blunt the benefits.
• Fitment requires verifying compatibility with the vehicle VIN or OEM reference numbers before installation.
