So glad I found this OEM PCV and hose together. I wasn't aware that these needed to be replaced at every oil change and the PCV to help keep vehicle operating good. This little part and hose were a life saver. Of course, the PCV may be the only part that needs replacing because the hose may not be damaged or clogged but I do them both to be on the safe side. As a female that's new to doing my own vehicle repairs, I don't want to have to climb back underneath the hood of my 2000 Ford Expedition 4.6L V8 Triton XLT to just do that hose since it is behind the Throttle Body. I will be ordering more from 1AAUTO to maintain my vehicle's proper maintenance and performance.
