All of the major air tubing for this system is trim-to-fit, meaning it’s a little long when you take it out of the box but a clean, perfect fit is easily achieved with a little trimming. Nick uses the tubes’ clamps as guides for achieving straight cuts. All of the ductwork leading into and out of the blower and intercooler is well-engineered and installs without any major drama. A billet ProFlow surge valve is positioned in the discharge tract. While we think venting it to the atmosphere would be cool, the bypassed air is channeled back into the inlet.
