was interested but could not afford that price,
"Installing a CSF 6029 intercooler and KC turbo in a 2003 E 350 and needed more clearance for the new cold air. Took two of the OE spyders and made a setup similar to yours. You advertise a larger diameter and better flow and spooling because of the larger diameter ID. I am wondering of how it can be larger in ID than the cast OE spyder?? I have billet intake plenums that use the standard 3" silicone hose connectors and the rest of the plumbing standard 3". How much larger in ID is yours over OE??"
