Upgrade or service a compatible ignition system with this set of four NGK DCPR8EIX-S Iridium IX spark plugs. Each performance-grade resistor plug features a fine-wire iridium center electrode, tapered-cut ground electrode and solid, non-removable terminal.
The fine-wire center electrode is designed to reduce the voltage required to produce a spark, while NGK’s copper-core construction supports heat dissipation across a broad operating range. This four-pack is intended only for engines specifically calling for the DCPR8EIX-S configuration or matching plug specifications.
