Bead-rolled charge piping so pipes will not blow-off with increased pressure

Engineered bracket mounts to engine so that charge piping & BOV move in unison with engine under all conditions

Billet CNC machined air temp sensor adapter welded directly onto charge pipe

No-Weld, CNC mandrel-bent, aerospace-grade aluminum tubing. As much as all fabricators, including us, try to eliminate stepped transitions with cut & weld piping, it is sometimes inevitable.
