Replaced my wife's mini plugs with these, and had no issues. Drives like a dream again, and starts first time every time. Excellent plugs.

Frankenstein's nipples....
Bought these for my Mini Cooper S R56. Not had the car long, and decided to give it a good engine service. Just as well, as the old plugs had hardly any centre electrode left. Old ones out, new ones in, and car starts and drives much better. I have to say that I'm a big fan of Bosch stuff, well engineered and made, and over the years, I've never had any problems with spark or glow plugs made by Bosch. You can probably buy cheaper, and more expensive, but these will do the job perfectly well, with no problems.

J’ai installé ses bougies sur un Hyundai Santa Fe 4 hybride de 2022. Ça marche super bien Partout ailleurs, on m’avait dit de ne pas les installer car il faut installer des bougies NGK d’origine à 150 euros les 4 Tu parles, Elles font, le travail aussi bien Et j’ai économiser 100 €
