This is a great thick hose but it's too stiff and will kink if you try to make a lot of bends in OEM size to fit.Of course these OEM elbows were factory formed, in my experience they weren't too tight for most hose brands.I had to make two 90's and two 180's.Both 180's buckled and the 90's buckled a bit but it was ok. These were the tightest of 2" radius bends, not too many to ask of a 3/8" ID hose. These aftermarket hose reels/springs that allowed the heater hose to twist in small radius bends
