This is NOT just a metal box! The HSP L5P Intake is constructed from high-quality materials and precision fabrication that make this cold air intake a work of art. Not only is this intake going to increase the looks of your engine bay, but it will increase your horsepower and lower intake temps.


Every HSP Intake has been designed to be a bolt-on addition without the need for tuning making our intake emissions compliant. Do not be fooled into thinking a compliant intake won't help with performance, because this intake can increase your truck by up to 20hp.


Every HSP tube is constructed using minimal bends while maximizing clearances. This will ensure the most direct and unrestricted path for air to flow. This will minimize drag and air tumbling which will improve the overall flow of air.


Our built-to-spec filters offer a massive surface with impeccable filtration to ensure maximum flow and performance. The HSP Filtration is a cotton cleanable media that can be cleaned using our HSP Filter Cleaning Kit.


Our powder coating process is the bread and butter of our products. Not only does the HSP intake delivers the power numbers you desire. It also adds a custom look to your truck with our various color options. Our high-quality coating process cleans and removes metal contaminants from the material before blasting and prepping for coating which sets up for a premium finish. Utilizing the Prismatic Powders' high-quality powders also ensures a quality & long-lasting finish that HSP will stand behind for years to come.
