These are not really connectors, but considering each Intercooler straight coupler is usually about $10-$15 i decided to go a differnt route. I have about 3.5 feet of 2.5 inch Goodyear Plycord Radiator hose. Probably make about15 couplers in total. This works very well, looks very clean. i used it on my entire setup.
$40
Will get pictures tommorow
