This kit includes nearly everything HSP Diesel offers for these trucks, making it a powerful upgrade right out of the box.\u003c\/p\u003e\n\u003ch3\u003eWhat Is the HSP Max Air Flow Bundle for the LLY?\u003c\/h3\u003e\n\u003cp\u003eThis bundle is ideal for those who want significant performance gains without piece-mealing components. It replaces key bottlenecks in the factory setup and is designed to boost airflow, power, and efficiency in a single upgrade package.\u003c\/p\u003e\n\u003ch4\u003eCold Air Intake\u003c\/h4\u003e\n\u003cp\u003eThe 4.5\" LBZ-style Cold Air Intake brings in maximum airflow and reduces intake temperatures. Coupled with HSPs heat shield box, it prevents hot engine bay air from entering. Tests show every 1°F increase in intake temperature results in an average 3 HP loss, so keeping temps down is critical.\u003c\/p\u003e\n\u003ch4\u003eMax Flow Intake Mouthpiece\u003c\/h4\u003e\n\u003cp\u003eHandcrafted for optimal flow and efficiency, this mouthpiece allows for a factory PCV reroute and eliminates the stock resonator box. This reduces oil contamination in the turbo and intake tract. (PCV kit sold separately: see 003-1-HSP.)\u003c\/p\u003e\n\u003ch4\u003eHot Side Intercooler Tube\u003c\/h4\u003e\n\u003cp\u003eStock tubes often fail due to poor routing and rubbing against the power steering line. HSP resolves this by redesigning the routing and increasing the diameter to a 3\" mandrel-bent tube for improved flow and reduced turbulence.\u003c\/p\u003e\n\u003ch4\u003eMax Flow Bridge \u0026amp; Cold Side Tube\u003c\/h4\u003e\n\u003cp\u003eThe 3\" two-piece Max Flow Bridge and matching Cold Side Tube increase charge air flow and ease installation. This combo minimizes boost leaks and maintains consistent pressure throughout the system.\u003c\/p\u003e\n\u003ch4\u003e2\" Passenger Side Up-Pipe\u003c\/h4\u003e\n\u003cp\u003eConstructed from heavy-wall 304 stainless steel and fitted with heavy-duty sleeved bellows, this upgraded up-pipe provides superior durability and smoother flow over stock designs.\u003c\/p\u003e\n\u003ch3\u003eWhat's Included:\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e1x Hotside Tube (HSP-IN-207)\u003c\/li\u003e\n\u003cli\u003e1x Bridge Neck (HSP-IN-209)\u003c\/li\u003e\n\u003cli\u003e1x Bridge (HSP-IN-222)\u003c\/li\u003e\n\u003cli\u003e1x Coldside Tube (HSP-IN-213)\u003c\/li\u003e\n\u003cli\u003e1x 4.5\" Cold Air Intake Tube (HSP-IN-150-1)\u003c\/li\u003e\n\u003cli\u003e1x 4.5\" Hole Heatshield Box (HSP-IN-748)\u003c\/li\u003e\n\u003cli\u003e1x Heatshield Box Lid (HSP-IN-746)\u003c\/li\u003e\n\u003cli\u003e1x Fabricated Turbo Inlet (HSP-IN-216-1)\u003c\/li\u003e\n\u003cli\u003e1x 2\" Stock Replacement Up Pipe - Passenger - Ceramic Coated (HSP-IN-280-C)\u003c\/li\u003e\n\u003cli\u003e1x 4.5\" Filter (RFB-413-RFAB)\u003c\/li\u003e\n\u003cli\u003e1x Bridge Neck O-Ring (RFB-670-RFAB)\u003c\/li\u003e\n\u003cli\u003e1x 1\/8'' NPT Brass Plug (RFB-811-RFAB)\u003c\/li\u003e\n\u003cli\u003e2x Bridge Neck Stud (RFB-902-RFAB)\u003c\/li\u003e\n\u003cli\u003e2x Bridge Neck 12-Point Nut (RFB-903-RFAB)\u003c\/li\u003e\n\u003cli\u003e4x 1\/8\" Aluminum Rivet (RFB-098-RFAB)\u003c\/li\u003e\n\u003cli\u003e3x 10-32 x 3\/8\" Button Head Screws (RFB-099-RFAB)\u003c\/li\u003e\n\u003cli\u003e16x Trim Lock (RFB-411-RFAB)\u003c\/li\u003e\n\u003cli\u003e1x Heatshield Box Lid Backer Plate (RFB-746-BP-RFAB)\u003c\/li\u003e\n\u003cli\u003e2x M4x.7x10mm Bolt (RFB-901-RFAB)\u003c\/li\u003e\n\u003cli\u003e2x 4.5\" T-Bolt Clamp (RFB-435-RFAB)\u003c\/li\u003e\n\u003cli\u003e1x 4.5\" X 4\" Straight Boot (RFB-444-RFAB)\u003c\/li\u003e\n\u003cli\u003e1x 2.25\" T-Bolt Clamp (RFB-420-RFAB)\u003c\/li\u003e\n\u003cli\u003e3x 3\" T-Bolt Clamp (RFB-422-RFAB)\u003c\/li\u003e\n\u003cli\u003e1x 3\"x4\" Straight Boot (RFB-430-RFAB)\u003c\/li\u003e\n\u003cli\u003e1x 2.25\" to 3\" Reducer Boot (RFB-441-RFAB)\u003c\/li\u003e\n\u003cli\u003e1x Up-pipe Gasket (Turbo Side) (RFB-821-RFAB)\u003c\/li\u003e\n\u003cli\u003e1x Up-Pipe Gasket (Manifold Side) (RFB-822-RFAB)\u003c\/li\u003e\n\u003cli\u003e1x Turbo Inlet O-Ring (RFB-628-RFAB)\u003c\/li\u003e\n\u003cli\u003e24x 5\/8\" Heater Hose (RFB-401-RFAB)\u003c\/li\u003e\n\u003cli\u003e2x 5\/8\" Worm Gear Clamp (RFB-403-RFAB)\u003c\/li\u003e\n\u003cli\u003ex 3\" T-Bolt Clamp (RFB-422-RFAB)\u003c\/li\u003e\n\u003cli\u003e1x 3\"x4\" Straight Boot (RFB-430-RFAB)\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eVehicle Fitment:\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eLLY: 2004.5-2005 (VIN Code 2)\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cstrong\u003eHow to verify:\u003c\/strong\u003e The 8th character of your VIN identifies the engine.
