NGK Laser Iridium Spark Plug IZKR7B (Box of 4) for Select Audi, Porsche, VW 2004-2009

Fits select 2004-2009 Audi A3 Quattro and TT Quattro, Porsche Cayenne, and Volkswagen Eos, R32, and Touareg models.

NGK Laser Iridium spark plugs (IZKR7B) are engineered to meet original equipment standards for ignition performance and long-term durability. These plugs feature a laser-welded iridium-tipped center electrode—six times harder than platinum—ensuring a high melting point and consistent spark over an extended service life. Specifically designed for modern distributorless ignition systems, these plugs utilize a platinum pad on the ground electrode to minimize wear and maintain gap integrity.

• Precision Construction: Iridium-tipped center electrode offers superior durability and spark efficiency.
• Dual Noble Metals: Platinum chip on the ground electrode provides even wear across both electrodes.
• Thermal Management: 98% pure copper core aids in heat removal to prevent overheating.
• Superior Insulation: Pure alumina silicate ceramic insulator provides high dielectric strength and heat transfer.
• Anti-Corrosion: Trivalent metal plating prevents seizing and corrosion in the cylinder head.
• Gas-Tight Seal: Triple seals eliminate combustion gas leakage for consistent cylinder pressure.
