Spark Plug Set For Ford F-250: Top Picks That Last

Choose the right spark plug set for Ford F-250 to fix misfires, restore power, and improve MPG fast.

You hit the gas, but your F-250 stumbles. The idle shakes. The check engine light blinks. I’ve been there. A fresh spark plug set for Ford F-250 can make your truck feel new again. It can boost throttle response, stop random misfires, and protect your coils. I compared top kits that fit popular F-250 engines like the 5.4L and 6.2L. I verified specs with OEM service data and 2025 parts catalogs. I kept things simple, honest, and based on what actually works on these trucks.

MAS Coil Pack + Platinum Plugs (SP515/SP546/DG511)

This bundle pairs eight DG511-style coils with platinum plugs that cross to SP515 and SP546. That means it targets the 5.4L Triton 3V era, which many F-250 owners still drive. If your Super Duty runs rough under load or throws coil-related codes, a matched coil-and-plug refresh can solve it in one go. The fit is straightforward for the listed applications. I like that the boots and connectors are tight. That helps stop carbon tracking, a common cause of repeat misfires on older 5.4L trucks.

For a spark plug set for Ford F-250, this works well when you want one box and done. The platinum plugs offer long life for daily use. The coils are a known upgrade over worn OEM units. Use anti-seize only if the plug maker says so and torque carefully to spec to protect the aluminum heads. I suggest blowing out plug wells before removal. That keeps debris out of the cylinders. Do the job on a cold engine. You get smoother idle and better throttle tip-in after install.

TRQ Coils + Plugs + Wires (2010–2016)

This TRQ kit includes ignition coils, spark plugs, and wire leads for select 2010–2016 Ford trucks. It covers late 5.4L and early Super Duty years, including many F-250 models listed by the seller.

It’s a strong choice for fleets and weekend towers alike.

Pros

• All-in-one kit: coils, plugs, and wires
• Targets misfires from aging wire leads
• Noticeable improvement under load

DG508 Coil Pack + Iridium SP479 Set

This set pairs DG508 coils with iridium SP479 plugs. Iridium tips last longer than basic copper and often outlast platinum in harsh use. If your F-250 sees lots of stop-and-go or dusty sites, long-life plugs can reduce service time. The coils come ready to drop in, and the iridium plugs handle heat well. I like this combo for trucks that run every day and need consistent spark.

For a spark plug set for Ford F-250, choose this when you want fewer plug changes. Check the gap as directed for your engine. Do not over-gap iridium tips. They are durable but should be handled gently. Replace any torn coil boots during install. A tight seal keeps moisture out. After the change, cold starts get cleaner, and the exhaust note evens out. It’s a practical upgrade for older engines you rely on.

Pros

• Iridium plugs offer very long life
• DG508 coils fit many legacy Ford V8s
• Stable spark in tough conditions
• Good for daily work trucks
• Helps smooth cold-start behavior

Cons

• Not intended for late 6.2L platforms
• Higher cost than basic copper
• Requires careful gapping and handling

My Recommendation

Get this if you want fewer service intervals and steady performance. It’s a spark plug set for Ford F-250 that keeps older engines running clean with minimal downtime.

If your 2017 truck has a light surge under load or a random misfire, aging wires are often the cause. Replacing all three parts gives the cleanest fix.

As a spark plug set for Ford F-250 from the aluminum-block 6.2L era, this makes sense. It saves time by matching lengths and connectors. I suggest marking wire positions before removal. Keep the harness tidy and clipped. After install, the 6.2L usually feels snappier and more consistent at highway merge speeds.
