6G43-07-10056-PK contains four plugs. A full V8 set needs eight plugs, or two Aston Martin packs. Check the pack size when buying NGK 97105.

Before ordering

  • For the listed naturally aspirated V8 engine only. This is not the AMG 4.0-litre twin-turbo Vantage plug.
  • Confirm the VIN-specific catalogue reference 6G43-07-10056-PK before ordering. The published CD33-12405-AA / SITR7A11G match is V12-only.
  • NGK application dates and vehicle registration years can differ. Confirm engine code and build date; modified engines need a separate specification.
Evidence for this match

NGK cross-references 6G43-07-10056-PK to IFR7N10 (97105) and lists the 4.3- and 4.7-litre Vantage applications separately. Aston Store identifies the genuine four-plug pack as NGK for both engines.
