There are various dressing and other preparations for hoses and wires under the hood. Do they actually keep them in better condition so they are more reliable and last longer -or- is just for the eye?
Recommendation for the best ones would be appreciated?
I never ran across any.
There’s some where the covers might act as a heat or weather shield, but for the most part they’re there to keep everything tidy. They help mechanics keep everything together and makes sure that loose wires or hoses don’t touch any moving parts.
EDIT: Oh, you mean aftermarket ones? Unless you’re doing some custom underhood work, there’s no reason to add them if they weren’t there originally.
These hose/belt dressings are for appearience purposes only. They do nothing for hose/belt longevity.
