This is a highly effective upgrade over the restrictive factory component and a must-have for anyone looking to improve airflow and overall performance.\u003c\/p\u003e\n\u003ch3\u003eWhy You Need the HSP Stock Turbo Inlet Horn\u003c\/h3\u003e\n\u003cp\u003eThe factory turbo inlet horn on LB7 trucks is poorly designed and highly restrictive. Its small diameter and awkward bends limit airflow to the turbocharger, choking its performance. This component also offers no visual appeal or performance benefit under the hood. HSP Diesel recognized the need for improvement and delivered.\u003c\/p\u003e\n\u003ch3\u003eWhat Makes the HSP Stock Turbo Inlet Horn Different?\u003c\/h3\u003e\n\u003cp\u003eHSPs version features a massive 3.5\" diameter far superior to the OEM part. The larger, smoother interior increases airflow and reduces restrictions. This allows the stock IHI turbocharger to spool faster and breathe easier, which translates into improved power and torque. Many customers report noticeable gains with just this part alone, and when paired with the HSP Cold Air Intake, it can help lower exhaust gas temperatures (EGTs).\u003c\/p\u003e\n\u003ch3\u003eWhats Included\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e1x Max Flow Inlet Horn (HSP-IN-235)\u003c\/li\u003e\n\u003cli\u003e1x LB7 Turbo Inlet O-Ring (RFB-819-RFAB)\u003c\/li\u003e\n\u003cli\u003e3x M6x1.0x20mm Button Head Screws (RFB-908-RFAB)\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eFitment\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eLB7: 2001-2004 (VIN Code 1)\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cstrong\u003eHow to identify the VIN code:\u003c\/strong\u003e The 8th character of the VIN indicates engine type, while the 10th character identifies the model year.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eSpecial Note:\u003c\/strong\u003e Only install this part using the supplied bolts.
