You see 4 injectors for 45 euros! You can't beat this price, can you? Those are just injectors, they shouldn't be too complicated. The packaging isn't bad, but once you get them you realize how cheaply made they are. The tip is very malleable plastic if that makes sense. If you get the engine hot enough, the tips will start to melt. If that doesn't get in the way, then the smaller o-rings/seals on top of the injector that go into the fuel rail are VERY poorly made. They are almost brittle and don't conform to the head very well. They broke right after installation. I had to take 4 o-rings from used injectors. and the large O-ring was also very loose. The injectors need to be a fairly tight fit in the cylinders, but these injectors are free to slide forward in the large o-rings they come with. A big enough protrusion and if your rail is installed incorrectly your injectors will come right out of the engine. Save yourself the hassle and spend an extra $20-30 on name brand parts.
