Picking the best spark plugs for your Ford F-150 ain’t just about buying what’s shiny or expensive. You mess that up, and next thing you know—rough idle, lost power, or way worse mileage than usual. Different F-150 engines like the 5.0L Coyote, 3.5L EcoBoost, or older 5.4L Triton all need different spark plug types, gaps, and heat ranges. One plug ain’t gonna fit ’em all. This list of 5 solid options will help you skip the junk and get ones that actually fire right and last long.

How to Choose the Best Spark Plugs for Ford f150
You got a Ford F-150, so you already care about power and performance. But you leave bad spark plugs in there too long or grab the wrong ones, and that truck’s gonna feel like it’s dragging a trailer even when it ain’t. Folks overlook plugs like they don’t matter, but they do. A lot.
Know Your Engine Before Buying Anything
First thing, don’t just Google “best spark plugs for Ford F150” and buy whatever pops up. Your engine type matters more than people think.
You got a 3.5L EcoBoost? Then you’re probably gonna need iridium spark plugs gapped right for turbocharged engines. Same with the 5.0L Coyote V8—those need plugs that handle high temps without breaking down early. And if it’s an older 4.6L or 5.4L Triton, things get trickier—those had plug thread issues in certain years.
So yeah, plug type ain’t one-size-fits-all for Ford F-150 spark plug replacements.
Types of Spark Plugs: Not Just About Price
People just grab the cheapest thing at the parts store. Don’t. You gonna pay for it later when the idle turns rough or it misfires under load.
- Copper plugs: Cheapest. Works okay short-term but wear out quicker. Most mechanics don’t recommend them unless you’re flipping the truck.
- Platinum plugs: Bit better. Lasts longer. Not ideal for EcoBoost engines, though.
- Double platinum: More durable. Good if your F-150 is older and not turbocharged.
- Iridium spark plugs: Best for modern engines. They cost more but can last 100,000 miles if gapped right and installed properly.
- Ruthenium (newer ones): Some say they last even longer, but real-world testing still kinda limited. Ford don’t recommend these yet on all trims.
If you got a 2018 Ford F-150 3.5L EcoBoost, Ford usually recommends Motorcraft SP-580 or equivalent. But even then, make sure you’re matching part numbers.
Gap Matters More Than You Think
Don’t just toss in plugs straight from the box. Always check the gap. Even “pre-gapped” ones sometimes off a bit. For most F-150 EcoBoost, you’re looking at 0.030 to 0.035 inches. If you’re running higher boost, some guys go tighter—like 0.028—but you gotta know what you’re doing.
Wrong gap = misfires. Misfires = poor MPG, sluggish throttle, and sometimes cylinder damage.
Also, always use a proper spark plug gapping tool, not a coin or paperclip. Sounds dumb but folks do that.
Heat Range: Too Hot or Too Cold? Both Bad.
Spark plug heat range sounds boring but matters more than folks think. Go too hot? You’ll get pre-ignition and detonation. Too cold? Plug fouls and causes misfires.
Ford already knows what heat range your engine needs. Stick with stock heat range unless you tuned the truck or upgraded internals. Only time to go colder is if you tuned your F-150 for high boost or towing heavy constantly.
Some aftermarket plugs advertise “colder for performance” but unless you know what AFR and boost you’re running, you could mess up your motor.
Coil Packs and Plugs Work Together
Bad plugs mess up coil packs fast. Don’t ignore a misfire. If you’re changing plugs, and your Ford F-150 has over 80k miles, check if the coils are wearing. Especially if you got the 3.5L or 2.7L EcoBoost – those coils fire more often under boost.
Some mechanics swap both plugs and coils at same time, especially if one failed. That’s smart, saves labor later.
You’ll often see coil-on-plug systems in modern F-150s. If you drop something in there while changing plugs, you could mess up the coil, so be clean.
Install Tips You Shouldn’t Ignore
Don’t just yank the old ones out and jam new ones in. Always use anti-seize compound on older engines (but Ford says not to on newer aluminum heads). Torque matters too. Over-tighten and you’ll strip the head. Too loose and they back out.
Ford usually calls for 13 lb-ft to 15 lb-ft torque for plugs in aluminum heads. Use a torque wrench, not guesswork. Also, never install plugs on a hot engine. Threads expand and things go sideways fast.
