I have tbolt on most of the couplers. Then on the one that keeps blowing off it has the cheapo hose type clamps. The clamps are holding up and they stay tight, but I think the weak pepboys coupler is crap.

All of the couplers that came with my intercooler have held up really well but I'm worried that when I get the trouble spot fixed it might blow out some of those too.

I like the idea for the heavy duty hoses though. I'm looking for alternatives to the weak couplers that they sell at parts stores that don't seem to like boost. I found some at siliconintakes.com and the two that I ordered from them are perfect but I was looking for something local that I can pick up kind of quick.
