The quality of these spark plugs is excellent. After using them for 4 years, I bought them again and put them in my car. They are the best.

Perfect OEM Replacement for Mercedes C300 – Smooth Performance!
I purchased 6 of these BOSCH YR7MPP33 spark plugs to replace the originals in my Mercedes C300, and they worked flawlessly. Installation was straightforward, and they fit perfectly with no issues. Right after replacing the plugs, I noticed smoother acceleration, improved fuel efficiency, and overall better engine responsiveness. These are high-quality double platinum plugs, and it shows — they deliver consistent performance and are built to last. If you're looking for a reliable OEM replacement that matches Mercedes specs, this is the one. Highly recommend for anyone doing spark plug maintenance on a C300 or similar models!

Un classique
Tres bonne bougie de marque. Une techno performante. Montage d origine qui a déjà duré plus de 100 000km et c est reparti pour autant. Vaut son prix sans hesitation.
