Description

NGK's iridium spark plugs deliver superior ignition reliability with a finer electrode design that demands less voltage from your ignition system, reducing wear on critical electrical components over time. The smaller iridium electrode fires more consistently than conventional plugs, translating to better cold starts, cleaner combustion, and extended service intervals—critical advantages whether you're running a street engine or pushing track performance. Backed by NGK's reputation as the industry standard, the DR7EIX 5686 is engineered for durability and precision ignition in demanding applications.

  • 1/4 size conventional nickel
  • Lower voltage requirement
  • Enhanced corrosion resistance
