Will these spark plugs fit my Ram 1500 5.7L V8?

Yes — these plugs are specified for Ram 1500 5.7L V8 models from 2011 through 2021, including Big Horn and Crew Cab 4-door configurations. Always verify engine displacement and year against your vehicle’s VIN or current spark plug part numbers before ordering.

• Compatibility: Ram 1500 5.7L V8, model years 2011–2021
• Check: confirm engine code and VIN when in doubt
• OE cross-reference: direct replacement for part number 4024123628

How are these SYKRSS iridium plugs different from standard plugs?

Iridium tips provide a harder, more erosion-resistant electrode than conventional nickel designs, which helps the spark remain sharp over many miles. That durable electrode typically improves ignition consistency and can reduce the rate of carbon fouling compared with lower-grade materials.

• Iridium center electrode for improved wear resistance
• Pre-gapped to 0.7–0.8 mm (0.028"–0.032") for correct ignition spacing
• Constructed for high-temperature stability in gasoline OHV engines

What should I expect during installation and service life?

Each plug ships pre-gapped and ready to install, so typical installation is quick with the correct socket and torque procedure. Service life varies by driving conditions, but iridium plugs generally last longer than standard plugs; follow manufacturer torque specs and replacement intervals for best results.

• Pre-gapped for hassle-free replacement
• Install with proper torque and anti-seize practices as recommended
• One 16-pack provides a full set for a V8 engine
