2002 Toyota Hilux Surf spark plugs: what they do and when to replace them

Whether spark plugs are relevant on a 2002 Toyota Hilux Surf depends on the engine fitted. According to Toyota repair manuals for the 185/215-series Hilux Surf/4Runner (e.g., RM835E for the 5VZ‑FE V6 and RM717E for the 3RZ‑FE 2.7), petrol variants use spark plugs, typically gapped to about 1.1 mm. Diesel variants such as the 1KZ‑TE and 1KD‑FTV do not use spark plugs at all
