HSP Diesel 2003-2004 Chevrolet / GMC Max Air Flow Bundle - 183-HSP

Featuring a mandrel-bent 4.5-inch intake tube for massive airflow gains, HSP's signature heat shield Box eliminating unwanted hot air entering the cold air intake. For every 1-degree 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 2003-2004 Duramax trucks is very restrictive and failure-prone. The factory intercooler tubing is only 2.25 inches in diameter and has a 90-degree 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.

HSP's solution to this problem is to run the hot side tube directly into the intercooler using race-proven 5 layer silicone boots resulting in lower temperatures, better airflow, and added clearance in tight places.
