Very nice, high quality product. The installiation instructions are okay but the poor 6.5mm drill bit for the press-in nuts, failed on a harder area of the steel inlet cap. Unfortunately I didn;t notice that the bit had actually become undersized, as a result the nuts would not press in correctly and fell out. Once I realized the issue, I had to buy a new, better drill bit to size the holes correctly. Other than that, an excellent product
