Granatelli MPG Plus 35,000V Coil-On-Plug Kit for Ford 4V 4.6L/5.4L - 25-4001MPG

GRANATELLI MPG PLUS • FORD 4V IGNITION

A CLEANER IGNITION CONNECTION CAN MAKE A GOOD 4V RUN EVEN BETTER.

The Granatelli 25-4001MPG MPG Plus Coil-On-Plug Coil Pack & Connector Kit upgrades compatible Ford 4-valve Modular V8 engines with a complete high-performance ignition package rated at up to 35,000 volts.

Unlike a basic replacement coil set, the MPG Plus package combines upgraded coil packs with Granatelli’s stainless-steel coil connectors to create a low-resistance path between the coil and spark plug while retaining a direct-fit Ford coil-on-plug layout.

What Makes the MPG Plus Version Different?

The focus of the MPG Plus ignition system is not simply maximum coil voltage. Granatelli pairs the performance coils with its stainless-steel connector technology to minimize unnecessary resistance between the coil and spark plug.

That makes 25-4001MPG a strong choice for street-driven Ford 4V owners looking for improved ignition efficiency, throttle response and dependable spark delivery without moving to an extreme race-oriented coil package.

Designed Around Ford’s 4-Valve Modular V8

Ford’s 4V Modular engines were used in some of the most recognizable performance cars of the era, including the Mustang Cobra, Mach 1 and Shelby GT500. The 25-4001MPG maintains the factory-style coil-on-plug arrangement while upgrading the electrical path from the coil to the spark plug.

Good Choice For

? Daily-driven Ford 4V builds • ? Mustang Cobra • ? Mach 1 • ? Shelby GT500 • ? Stock or tuned engines • ? Intake and exhaust upgrades • ? Aging factory-coil replacement

Replace the Ignition System as a Matched Set

Replacing the complete set of coils and connectors at the same time helps avoid mixing new performance components with older factory ignition hardware. The result is a consistent coil and connector package across all eight cylinders.
