🔧 Install Tips
- Pre-Gapped: NGK Laser Iridium plugs come factory pre-gapped for this specific application. Do not adjust the gap, or you risk damaging the delicate iridium tip.
- Torque Specs: Use a torque wrench (typically around 18-22 Nm for this size) to avoid over or under-tightening. This is crucial for a proper seal.
- Install in Pairs: Always replace spark plugs in pairs to maintain balanced ignition across both cylinders.
- Service Interval: These last significantly longer than standard plugs, but we still recommend inspecting them every 5,000 to 10,000 miles to prevent fouling.
