This kit features a mandrel-bent 4.5" intake tube for massive airflow gains, HSP's signature heat shield Box eliminates unwanted hot air entering the cold air intake. For every 1° increase in intake air temperature will result in a 3hp loss. This kit also features HSP's high-flow turbo mouthpiece that outflows any ported mouthpiece on the market. It will also include HSP's hot side and cold side intercooler piping.

The factory intercooler tubing on Duramax trucks is very restrictive and often fails. The factory intercooler tubing is only 2.25" in diameter and has a 90° boot at the intercooler that is prone to failure. With this routing there is a possibility of the hot side intercooler tube rubbing on the power steering line, causing the line to rub a hole in the tube resulting in a boost leak.
