Escort cosworth inlet hose
 

Can anybody offer some advise please , I'm running a Swedish plenum and airtec RS500 style 60mm intercooler and I'm having issues with the silicon hose at the moment in using a s shaped hose from a random turbo but it's not ideal and restricting the air flow I did buy a hose with dump value take off from rouse but that was no good either , can anybody help it would be much appreciated ?
