High-performance iridium spark plugs engineered by Yoshi Motors as a direct-fit replacement for NGK-specified Ford EcoBoost F-150 3.5L engines, delivering long-lasting, consistent ignition.

These Yoshi Motors Iridium spark plugs are made to match the fit and firing characteristics expected for Ford EcoBoost 3.5L V6 engines found in F-150 models. Built with an iridium center electrode and precision-ground tips, they prioritize stable combustion, extended service life, and resistance to heat and wear. The design aims to give owners an affordable replacement option that restores reliable starts and smooth operation without altering engine tuning.

Will these spark plugs fit my F-150 EcoBoost 3.5L?

Yes—these plugs are produced to the specifications commonly used as NGK replacements for the Ford 3.5L EcoBoost V6. Confirm fitment by matching part numbers and thread size to your vehicle’s service manual or the compatibility chart provided by the seller.

• Direct-fit intended for Ford EcoBoost 3.5L engines in F-150 models
• Matches NGK-style dimensions and seat type for easy installation
• Check vehicle year and engine code before purchase

How do iridium electrodes benefit engine performance?

Iridium is harder and has a higher melting point than conventional materials, allowing a smaller center electrode that produces a sharper spark. That can improve ignition reliability, especially under high-heat or high-compression conditions, and helps maintain consistent spark energy over a longer interval.

• Smaller, precise electrode improves spark focus and combustion
• Greater heat tolerance reduces electrode erosion and misfires
• Longer service life compared with standard copper or nickel plugs

What should I expect during installation and maintenance?

Installation follows the same steps as replacing any threaded spark plug: remove ignition coils, unthread old plugs, gap-check new plugs if necessary, and torque to Ford spec. Routine inspection intervals are extended with iridium plugs, but periodic checks and proper torque are important to avoid leaks or thread damage.

• Use correct torque values to prevent thread damage or combustion leaks
• Inspect ignition coils and boots when replacing plugs
• Gap is typically preset—verify before installation if desired

Why choose Yoshi Motors replacements over OE or other aftermarket plugs?
