Color was dirty and almost looked like the liquid had reacted allready. Price was cheaper than many other products, but I reccoment spending that little extra for a better quality kit ### ⭐⭐⭐⭐⭐ Goed voor Controle *by on Reviewed in the Netherlands 11 April 2026* Dacht dat mijn BMW 325i n52 een lekke koppakking had.
