Review: Good but all of them needed to be re-gapped - Good but all of them needed to be re-gapped. Checked on multiple gauges and calipers. all 4 of them were too closely gapped. Description said it was pre-gapped .044" more like .036"
Review: conforme vraies bougies NGK - 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

### ⭐⭐⭐⭐⭐ Can feel the difference.
*by Z***N on 16 March 2026*

Check the resistance to be sure they are authentic. It should be between 4 and 5.5 ohms. Check the gap, it shouldn't be off more than 1 degree +/-. Watch videos on how to see the difference between real and fake. These work flawlessly in my 2.2 Honda. The gap is spot on. Been two years now...seem like new.
