I redid the turbo (Silver Phatshaft 62) the cooler (Banks Technacooler) the intake horn (Banks) on my 04 truck. When I got the Technacooler I checked for anything inside of it. Set it on end with the pressure IN side down and lightly tapped it. I found about 1/2 a thimble full of welding spall in the cooler.. I called Banks with a friendly call to tell them what I found, and then sent the spall via certified letter to them, "attn Engineering dept." Did not get a call from them that they got the envelope , so I called after one of the turbo boots failed (only one ply of cord) I wanted to let them know that debris of any amount is NOT OK in the cooler, and I had a boot failure. I got brushed off by the fellow I talked to. More or less told me that it was not a concern of his or to Banks. I was not expecting anything from them other than a "Thanks we will do a better job" but did not even get that .. Maybe someone had a bad day, it kind of ran over to me. To say I am dissappointed is a understatement. I would be hard pressed to reccommend Banks to any of my customers.
