conforme vraies bougies NGK. pour ceux qui se posent la question, il existe des contrefacons NGK; celles ci ne le sont pas, elles sont arrivés rapidement, parfait état. Sur honda accord 2.0i es 147cv année 1999, zfr6fix-11 parfait, meilleur ralenti, plus doux, plus réactive, je sens une petite différence. Le gap est juste en dessous de 1.1mm, ce qui est recommandé pour ce modèle de véhicule et ces bougies: donc pas eu à retoucher quoique ce soit. n'hésitez pas, ce vendeur est sérieux, les bougies sont de qualité. je partage cela pour les prochains qui passent après moi, ca peut aider. cordialement
