Overview

Each set of four plugs arrives pre-gapped by Mountune to specific tolerances, ensuring reliable ignition and smoother acceleration for daily driving or lightly tuned vehicles.
Show original supplier description
The NGK Ruthenium spark plug set serves as a vital component for maintaining consistent performance in Ford EcoBoost engines, which are prone to rapid spark plug wear under high-boost conditions. Electrode degradation and increased gaps in standard plugs can lead to engine misfires, rough idling, and decreased power. Each purchase includes a set of four spark plugs that are pre-gapped by Mountune to application-specific settings, including .026" for the Focus RS, .028" for the Focus ST and Ranger, and .030" for the Fiesta ST and F150 Raptor. This customization ensures optimal fitment and eliminates the need for manual adjustment during installation. This product is intended specifically for off-highway use. Please note that installation on vehicles driven on public roads may conflict with local emissions regulations and motor vehicle safety standards.
