These are a 6-piece set of genuine NGK Ruthenium HX spark plugs, pre-gapped to 0.032" and made to replace the originals in Ford F-150 2.7L V6 models from 2015 through 2019.

Designed as a direct-fit replacement, this Sixity Auto listing supplies authentic NGK Ruthenium HX spark plugs in original packaging and includes the hardware needed for straightforward installation. The plugs use NGK's Ruthenium HX electrode technology for consistent ignition performance and long service life, and each plug is prepared to the factory-specified 0.032" gap for the listed F-150 applications. Before installation, confirm compatibility with your vehicle’s VIN or the retailer fitment tool.

Why choose NGK Ruthenium HX plugs for my F-150 2.7L V6?

NGK’s Ruthenium HX design balances durability with ignition efficiency. The ruthenium-tipped center electrode resists wear longer than standard nickel plugs, helping maintain stable spark performance over many miles.

• Ruthenium center electrode for extended life and consistent spark
• Pre-gapped to 0.032" to match Ford factory specs
• Sold as a 6-pack to replace all cylinders at once
• Genuine NGK parts supplied in original packaging

How easy is installation and what does 'direct replacement' mean?

Direct replacement means the plugs match OEM size, thread pitch, reach, and resistor value, so they install without modification. If you’re comfortable removing ignition coils and swapping plugs, this is a job many DIYers can complete with common hand tools and a torque wrench.

• Fitment: Ford F-150 2.7L V6, model years 2015–2019
• Includes necessary hardware and original NGK packaging
• Pre-gapped to 0.032" — verify gap before final install
• Use correct torque for plug specifications to avoid damage

What performance or maintenance benefits can I expect?

Upgrading or replacing worn plugs with NGK Ruthenium HX can restore reliable ignition and help the engine run smoothly. While not a performance modifier by itself, new, correctly gapped plugs reduce misfires and support optimal fuel combustion.

• Reduced misfire risk compared to worn plugs
• More consistent starts and idle quality
• Longer service interval from ruthenium electrode durability
• Compatible with factory ignition systems—no reprogramming required

How should I check fitment and care for these plugs?

Always confirm fitment using your vehicle VIN, OEM part numbers, or the online fitment checker before purchase. After installation, inspect plugs at regular service intervals and replace if signs of electrode wear, fouling, or damage appear.

• Confirm compatibility with VIN or fitment tool before buying
• Check gap 0.032" and adjust only if necessary with proper tools
• Replace as a full set (6 plugs) to maintain even performance
• Follow Ford torque specs and ignition coil reinstallation steps
