• Part number: DILZKR7B11G; NGK stock: 95350

How do these spark plugs affect engine performance and longevity?

The iridium fine-wire center electrode improves ignitability and combustion stability, which helps maintain smooth idling and steady throttle response. Iridium’s high melting point and the platinum ground tip slow electrode wear, extending the useful life compared with conventional plugs.

• Iridium center electrode for improved ignition efficiency
• Platinum ground electrode to reduce erosion and maintain gap
• Resistor type for noise suppression and stable electronics operation

What are the key technical specifications I should know?

These plugs are built to precise dimensions and materials to match OEM requirements. Key specs affect fit, heat range, and mechanical compatibility with your engine head and ignition system.

• Reach: 1.043" (26.5 mm); thread diameter: 12.0 mm
• Hex size: 5/8" (16 mm); pre-gap: 0.044" (1.1 mm)
• Heat range: NGK designation 7; center electrode: iridium over copper core
• Ground electrode: dual fine electrode design with platinum tip

What should I expect during installation and maintenance?

Installation is straightforward for any technician familiar with spark plug service, but follow torque and gap recommendations specific to your vehicle. Replace all plugs at the intervals suggested by the vehicle manufacturer and inspect ignition coils and wires when servicing.

• Torque to vehicle manufacturer specifications to avoid damage
• Verify gap if performing custom tuning; plugs ship near OEM pre-gap
• Replace in sets of six for balanced cylinder performance
