Excellent replacement hose - especially considering the complexity of this hose. It's been in place for weeks now, no leaks or problems. There are literally 4 points to actually connect this hose to the car ('03 Altima). Therefore, these moments have to be precise β and they are. This hose set could easily be considered a "factory replacement part" - in fact I think the thermal insulation material can exceed OE standards. both hoses are side by side when you fit the two center mounting brackets (supplied with the new hose) to the new hose so you can roughly position them before inserting the hose into the very tight space between the engine and bulkhead . I suggest you watch a few YouTube videos on removing/replacing so you understand this first; it was very helpful for me. Much luck.
