Just bought an air filter re-location pipe, it starts of as 2.5inch at the maf end but then drops to 2inch about half way down. Do you guys think this is a bit restrictive? 2inch is smaller than the standard pipe.Is the case the bigger the better when it comes to turbo inlets. Or is there benefits to having a slight restriction to maybe speed up air flow .Bear in mind that im still running standard boost/fuelling .
