scrap egr hoses are all very nice, but how long have they been on the car and how strong are they. you may even get it home, put it on the car and then find out its split anyway.
When oem rubber hoses are prone to splitting, why buy a second hand replacement that could split quickly. Fords new egr hoses are over £50, silicone ones are less than £30 for example
It makes more sense to buy a hose that you can put on and forget rather than a second hand one you are likely to have to keep replacing and which will end up costing more after you have bought several of them.
there are alot of parts that are much better buying from a scrappers than new, but oem parts that are known to fail arent one of them.
