Improved Spark with One Step Colder Heat Range than Stock

When you throw an aggressive tune and a wide range of F150 EcoBoost Performance parts at your very own 3.5L V6, you'll need a few bits of fine tuning to get your EcoBoosted motor running at its best. These NGK Iridium IX spark plugs are a nice upgrade that have a one step lower heat range than OEM for heavily modified and tuned trucks that still feature NGK's legendary reliability and performance. The Iridium IX plugs are built from the ground up to resist corrosion and fouling while providing improved spark, reliability, and versatility over your truck's factory spark plugs. This full set of six iridium spark plugs from NGK are an excellent choice for tuned vehicles that have wore out the welcome of the factory plugs.

High-Quality Iridium Tip and Corrosion-Resistant Design

The NGK Iridium IX spark plugs are named after their .6 mm laser-welded iridium tip that delivers a powerful arc while being highly resistant to corrosion and fouling. The insulator and electrode feature Trivalent metal plating that offers up vastly improved anti-seizure and anti-corrosion properties than traditional spark plugs. These plugs have a tapered electrode that reduces quenching while making regapping extremely simple.

  • Thread Size: 14mm
