Maybe this will help sum it up. GTM's oil cooler setup had faulty lines, of course they stepped up and addressed the issue. I just installed their oil cooler last week, sorry I haven't had a chance to update my thread with pictures hopefully this weekend. The new lines are made by the same manufacturer as the core, namely Setrab. All I can say is that when I unpacked everything the lines are the first thing I went after and they are DIESEL! They will not explode, the workmanship and quality of the piece is 10/10. This leads me to believe that any subsequent explosion in an application such as mine would be by faulty install.
Get a cooler, the Z needs it, after getting the big GTM cooler I haven't seen 220
. You're lines won't explode and it goes a long way toward maintaining engine life.
