The hose is very undersized for the barbs that you have to slide it onto, it may be an issue installing it in a very very tight space to begin with. I did it with my intake completely removed and installed the PCV on the hose before I put it all back in the car.
On a positive note, it is a different material than the one that I replaced it with, there seemed to be multiple layers to the hose that I replaced, that hose had a rigid outer layer that disintegrated and allowed hose to collapse. This hose appears to be all solid construction without laminated layers.
The hose was the exact same as the original right down to the writing on it, and I'm assuming that it's going to last just as long as the factory original, very pleased with my purchase.
