Fitment Notes

• NGK 94833 is also identified as PLFER7A8EG and cross-references OE numbers 06K 905 601 B, 06K 905 601 D, and 06K 905 611 C.
• Fitment is engine-code dependent; verify the engine code and OE spark-plug number before ordering.
• Applications include selected 1.8L and 2.0L Volkswagen Group turbocharged engines; this part must not be assigned to other engine families solely by model name.
• For Golf Mk7 2.0L GTI applications, NGK identifies engine codes CHHA/CHHB for this plug.
• Some vehicles listed above have multiple engine options; only the specified compatible engine configurations use 94833.
• 2025 coverage is confirmed for selected Audi A4, Audi A5 Sportback, and Audi Q7 2.0L applications.
• 2026 vehicle applications are not confirmed for NGK 94833.
• Sold individually; vehicle-specific engine quantity must be verified before ordering.

Product Description

The NGK 94833 Laser Platinum spark plug, also identified as PLFER7A8EG, is an OE-style replacement spark plug developed for selected turbocharged Volkswagen Group engines. It is used across compatible Audi, Volkswagen, Porsche, SEAT, and Skoda applications with specific 1.8L and 2.0L engine configurations. The plug uses a platinum center electrode, single ground electrode, and 1 kOhm resistor to provide consistent ignition performance and electrical-noise suppression.

The 94833 features an M14 x 1.25 thread, 26.5 mm reach, 16 mm hex, flat gasket seat, and approximately 0.8 mm pre-gap. Its ceramic insulator provides thermal and electrical resistance, while the copper-core construction assists heat transfer. Trivalent metal plating on the shell helps resist corrosion and thread seizure during service.

Because NGK 94833 is shared across numerous Volkswagen Group platforms and engine codes, model-level identification alone is insufficient for guaranteed compatibility. Confirm the exact engine code and OE spark-plug reference before installation. The plug is sold individually, and the required quantity depends on the engine configuration.
