Yoshi Motors Coil & Plug Set
The Yoshi Motors set gives you everything for a full tune-up. It pairs NGK iridium plugs with new ignition coils.
This combo is perfect if your truck has high miles. You get a smooth idle and better throttle response right after the install. The coils are built to handle the heat and stress of the Ecoboost engine.
Installation is simple with the right tools. You won’t need to buy anything else to get the job done right.
Pros:

My Honest Opinion:
If your F150 is past 80,000 miles, this Yoshi set is a smart buy. Replacing the coils and plugs together can prevent future problems. It’s a bit more money upfront, but it saves you time and hassle later.
Coil and Plug Combo
This all-in-one kit replaces both your spark plugs and ignition coils. It’s a direct fit for the 3.5 Ecoboost.
The iridium plugs provide a strong spark for better combustion. Your truck will start easier and run smoother on cold mornings. The coils are made to last and resist the engine’s high temperatures.

This is a solid choice if you have a misfire or check engine light. Replacing everything at once fixes most common ignition issues. I’d recommend this for trucks with over 100,000 miles on the original parts.
