Review: Desastrosas - Desastroso. Son bujías que aparecen como compatibles con mi vehículo. Se han instalado a su par de apriete hace menos de 2.000 kms y siguiendo todos los cuidados necesarios para su correcta instalación. Han resultado nefastas, una de ellas presenta fugas por la cerámica, venían con diferentes distancias de electrodos y lo peor es que han ocasionado la avería asegurada en una de las bobinas (no tengo claro que hayan podido ocasionar daños en las otras 3 bobinas). Todo ello obliga, al necesario cambio de todas las bobinas y de nuevas bujías. Conociendo la marca NGK, dudo mucho que sean originales. Review: 100% perfect for my application. - Just as described.
