HSP Cold Air Intake's are quickly becoming one of the best performing intakes in today’s high-performance diesel world. Proven dyno numbers show our intake providing 20 additional horsepower and 58 pounds of torque on average to an already great performing engine. The HSP intake delivers the power numbers you desire, while adding a custom look to your truck with our various color options. Our cold air intake lowers intake air temperatures by including a heat shield box that separated the hot under hood temperatures from the filter. By design, the heat shield box will now draw in cold, fresh air from the headlight bezel and fender port. The 4'' mandrel bent tubing provides an extremely consistent and free-flowing path that enables us to outperform other intakes on the market. We teamed up with one of the industry’s best in filter manufacturing to ensure the longevity, and filtration that is essential to the life expectancy of your turbo charger. Don't be let down by the substandard, cheap intakes in today's market. Invest in the high quality and standards of HSP Diesel.
