Review: 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: Have used these since I purchased my Focus ST and Ecoboost Mustang. I have ran them since stock and tuned. I change spark plugs every 10 k miles. My Focus is big turbo pushing 25 psi on e30 and does not misfire during wot pulls at all. Mustang is stock turbo e30 and no misfires during pulls as well.
