2001-2004 Chevrolet and GMC 6.6L Duramax LB7 trucks. Whether your truck is stock, modified, daily driven, or part of a full engine bay build, this hot side tube is a proven upgrade over the factory intercooler pipe.\u003C\/p\u003E\u003Cp\u003EDesigned to improve airflow, reliability, sound, and appearance, the HSP Hot Side Intercooler Tube replaces the restrictive factory-style pipe with a 3-inch mandrel-bent tube and high-strength silicone boots.\u003C\/p\u003E\u003Cp\u003E\u003Cstrong\u003EWhy Upgrade Your Factory Hot Side Intercooler Tube?\u003C\/strong\u003E\u003Cbr\u003EThe factory hot side intercooler tube gets the job done, but it leaves plenty of room for improvement. The factory pipe design can create unnecessary turbulence, uses connection points that may become failure-prone under pressure, and does not offer the clean engine bay appearance many truck owners are looking for.\u003C\/p\u003E\u003Cp\u003EHSP Diesel designed this upgraded hot side intercooler pipe to provide better flow, a stronger connection, and a cleaner finished look under the hood.\u003C\/p\u003E\u003Cp\u003E\u003Cstrong\u003EWhat Makes the HSP Hot Side Intercooler Tube Different?\u003C\/strong\u003E\u003Cbr\u003EThe HSP Hot Side Intercooler Tube is made from 3-inch mandrel-bent tubing. This design helps increase airflow while using smooth, sweeping bends to reduce turbulence inside the tube. With improved airflow of up to 40 percent, this upgrade helps support better performance and efficiency.\u003C\/p\u003E\u003Cp\u003EAnother key improvement is the straight-style connection to the intercooler. This replaces the factory-style lower intercooler boot connection, helping remove a common failure point and adding reliability for both stock and modified trucks.\u003C\/p\u003E\u003Cp\u003EAlong with the performance and reliability benefits, this hot side intercooler tube can also improve engine and turbo sound. Many customers notice a cleaner, more distinct turbo tone after installation.\u003C\/p\u003E\u003Cp\u003EHSP Diesel also offers this tube in multiple powder coat options, including custom colors, allowing you to match or contrast your engine bay setup.\u003C\/p\u003E\u003Cp\u003E\u003Cstrong\u003EFeatures\u003C\/strong\u003E\u003C\/p\u003E\u003Cul\u003E\u003Cli\u003EFits 2001-2004 Chevrolet and GMC 6.6L Duramax LB7 trucks\u003C\/li\u003E\u003Cli\u003E3-inch mandrel-bent hot side intercooler tube\u003C\/li\u003E\u003Cli\u003EImproves airflow by up to 40 percent\u003C\/li\u003E\u003Cli\u003ESmooth sweeping bends help reduce turbulence\u003C\/li\u003E\u003Cli\u003EStraight connection to the intercooler helps remove a common failure point\u003C\/li\u003E\u003Cli\u003EHigh-strength silicone boots included\u003C\/li\u003E\u003Cli\u003ET-bolt clamps included\u003C\/li\u003E\u003Cli\u003EImproved engine bay appearance\u003C\/li\u003E\u003Cli\u003EAvailable in multiple powder coat options, including custom colors\u003C\/li\u003E\u003Cli\u003EImproved turbo and engine sound\u003C\/li\u003E\u003C\/ul\u003E\u003Cp\u003E\u003Cstrong\u003EWhat\u0027s Included?\u003C\/strong\u003E\u003C\/p\u003E\u003Cul\u003E\u003Cli\u003E1x 3-inch mandrel-bent hot side intercooler tube (HSP-IN-LB7-207)\u003C\/li\u003E\u003Cli\u003E(1) 3-inch x 4-inch straight boot-430-RFAB\u003C\/li\u003E\u003Cli\u003E(1) 2.25-inch to 3-inch reducer boot-441-RFAB\u003C\/li\u003E\u003Cli\u003E(1) 2.25-inch T-bolt clamp-420-RFAB\u003C\/li\u003E\u003Cli\u003E(3) 3-inch T-bolt clamps-422-RFAB\u003C\/li\u003E\u003C\/ul\u003E\u003Cp\u003E\u003Cstrong\u003EVehicle Fitment\u003C\/strong\u003E\u003C\/p\u003E\u003Cul\u003E\u003Cli\u003E2001 Chevrolet Silverado 2500HD\/3500HD 6.6L Duramax LB7\u003C\/li\u003E\u003Cli\u003E2002 Chevrolet Silverado 2500HD\/3500HD 6.6L Duramax LB7\u003C\/li\u003E\u003Cli\u003E2003 Chevrolet Silverado 2500HD\/3500HD 6.6L Duramax LB7\u003C\/li\u003E\u003Cli\u003E2004 Chevrolet Silverado 2500HD\/3500HD 6.6L Duramax LB7\u003C\/li\u003E\u003Cli\u003E2001 GMC Sierra 2500HD\/3500HD 6.6L Duramax LB7\u003C\/li\u003E\u003Cli\u003E2002 GMC Sierra 2500HD\/3500HD 6.6L Duramax LB7\u003C\/li\u003E\u003Cli\u003E2003 GMC Sierra 2500HD\/3500HD 6.6L Duramax LB7\u003C\/li\u003E\u003Cli\u003E2004 GMC Sierra 2500HD\/3500HD 6.6L Duramax LB7\u003C\/li\u003E\u003C\/ul\u003E\u003Cp\u003E\u003Cstrong\u003EFitment by VIN Code\u003C\/strong\u003E\u003Cbr\u003ELB7: 2001-2004 trucks with VIN Code 1\u003C\/p\u003E\u003Cp\u003E\u003Cstrong\u003EHow to Find Your VIN Code\u003C\/strong\u003E\u003Cbr\u003EThe engine code is determined by the 8th character of the VIN number.
