PLFER7A8EG Double Platinum Spark Plug

The NGK PLFER7A8EG (Part No. 94833) is a genuine double platinum spark plug, manufactured to OE specifications and commonly fitted to VW Group performance engines, including many 2.0 TSI variants. Each plug is engineered with a laser-welded platinum tip on both the center and ground electrodes, ensuring a slow and even wear rate for extended service life and consistent ignition performance. Spark plugs are critical for igniting the fuel-air mixture in your engine. Worn or incorrect plugs can lead to misfires, poor fuel economy, rough idling, and a reduction in power. Replacing your spark plugs with fresh, correctly specified units like the PLFER7A8EG will restore the strong, consistent spark your engine was designed for, leading to a stable idle, smoother running, improved cold starting, better fuel efficiency, lower emissions, and excellent anti-fouling properties due to the twin platinum surfaces. This spark plug is designed for a wide range of VW Group vehicles, including Audi, Bentley, Lamborghini, SEAT, Skoda, and Volkswagen models, particularly those with 2.0 TSI and related petrol engines. Always replace spark plugs as a complete set for balanced ignition across all cylinders. Use a torque wrench to tighten to the manufacturer's specified value to prevent damage to the cylinder head or the plug itself. If your engine has been tuned or runs higher boost pressures, consult your tuner to ensure this heat range is suitable for your application. Key technical specifications include a 14mm outer thread, 26.5mm thread length, 16mm spanner size, 3.5mm spark position, platinum center electrode, a single platinum-tipped ground electrode, 1 kOhm interference suppression, a flat seat with gasket, and a ring type connector terminal. OE cross-references include 06K 905 601 B and 06K 905 611 C.
