NGK Laser Platinum Spark Plug Box of 4 (PKER7A8EGS) - 95463

The NGK Laser Platinum Spark Plug PKER7A8EGS (NGK #95463) is a premium, OE-engineered ignition component sold in a convenient box of four — making it the ideal one-stop solution for a complete spark plug service. Designed specifically to meet the demands of modern engines, NGK Laser Platinum spark plugs deliver stable idling, superior anti-fouling performance, improved fuel efficiency, and lower emissions compared to conventional nickel plugs. If you're sourcing quality NGK spark plugs for a Volkswagen Jetta, Audi A3 Sportback e-tron, or a compatible application, this set covers all cylinders in a single purchase.

Key Features & Benefits

• Laser-Welded Platinum Center Electrode (1.0 mm Fine Wire): The fine-wire platinum center electrode produces a more focused spark, enhancing ignitability and extending service life well beyond conventional nickel plugs — NGK rates longevity at up to 90,000 miles.
• Platinum Pad on Ground Electrode: Most NGK Laser Platinum plugs feature a platinum pad on the ground electrode, promoting even wear — a key advantage in distributorless ignition systems (DIS) common on VAG-platform vehicles.
• Trivalent Metal Plating: The shell's trivalent metal plating provides superior anti-corrosion and anti-seizing properties, making removal straightforward even after long service intervals — a genuine benefit when working on aluminum cylinder heads.
• Pure Alumina Silicate Ceramic Insulator: Provides superior mechanical strength and better heat transfer, keeping the plug operating in its optimal temperature range for consistent combustion and reliable starts.
• High-Grade Copper Core: A 98% pure copper core aids in heat removal, helping prevent overheating and pre-ignition under varied driving conditions.
• Corrugated Ribs: The ribbed insulator design prevents flashover — an unwanted discharge along the insulator surface — helping maintain a clean, reliable spark every cycle.
• Triple Seals: Triple seals prevent combustion gas leakage past the plug, maintaining compression integrity and protecting the ignition system.
• Engineered for OE Applications: These plugs are built to OEM specification tolerances, making them a direct, no-modification replacement in the vehicles they fit.
• Box of 4: Packaged as a set of four — exactly the quantity needed for a complete 4-cylinder engine service, saving you from ordering separately.

Frequently Asked Questions

Q: Are these spark plugs pre-gapped from the factory?
A: Yes. The NGK PKER7A8EGS comes pre-set to a gap of 0.031" (0.8 mm) from the factory. NGK generally recommends against re-gapping fine-wire platinum or iridium plugs, as doing so risks damaging the precision-welded electrode tip.

Q: How many spark plugs are included in this listing?
A: This listing includes a full box of 4 NGK Laser Platinum spark plugs (PKER7A8EGS), which is exactly the quantity needed to service a complete 4-cylinder engine.

Q: What is the expected service life of these plugs?
A: NGK rates the Laser Platinum PKER7A8EGS for up to 90,000 miles of service life, significantly longer than conventional nickel spark plugs.

Q: What torque should I use when installing these plugs?
A: NGK specifies 10.8–18 lb-ft for cast iron cylinder heads and 10.8–14.5 lb-ft for aluminum cylinder heads. Most modern VAG engines use aluminum heads, so stay on the lower end of the range and always use a calibrated torque wrench. The plug uses a gasket seat — ensure the gasket seats fully before torquing.
