These internal ridges cause boundary-layer separation and severe aerodynamic turbulence, starving the throttle body of laminar airflow at mid-to-high RPMs. Furthermore, the thin OEM plastic box sits directly in the engine bay without thermal barrier protection, allowing conductive heat soak from the radiator and engine block to elevate Intake Air Temperatures (IATs), which prompts the factory ECM to pull ignition timing and blunt torque delivery.\u003c\/p\u003e\n\n\u003ch3\u003eThe Engineering Solution\u003c\/h3\u003e\n\u003cp\u003eThis intake system replaces the factory bottleneck with a smooth-bore, mandrel-bent aluminum intake pipe finished in durable matte black powder coat. The continuous internal diameter promotes laminar charge velocity straight into the throttle body. An enclosed aluminum heat shield isolates the high-flow conical filter from hot engine-bay air behind the driver-side headlight, while an included reflective aluminum insulation mat shields against radiant thermal transfer. Multi-layer, 4-ply reinforced silicone couplers withstand vacuum collapse and extreme thermal cycling without degradation, sealing securely via stainless steel hardware while retaining factory \u003cstrong\u003eMAF sensor\u003c\/strong\u003e calibration without requiring an ECM retune.\u003c\/p\u003e\n\n\u003ch3\u003eWhat's Included\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e1 x High-flow air filter (washable and reusable)\u003c\/li\u003e\n  \u003cli\u003e1 x Black powder-coated aluminum intake pipe\u003c\/li\u003e\n  \u003cli\u003e1 x Black powder-coated aluminum heat shield\u003c\/li\u003e\n  \u003cli\u003e1 x Reflective aluminum heat shield mat material\u003c\/li\u003e\n  \u003cli\u003e1 x 4-ply silicone coupler\u003c\/li\u003e\n  \u003cli\u003e1 x 4-ply silicone elbow\u003c\/li\u003e\n  \u003cli\u003eSilicone vacuum hoses\u003c\/li\u003e\n  \u003cli\u003eAll necessary stainless steel button-head bolts, washers, locknuts, and band clamps\u003c\/li\u003e\n  \u003cli\u003eInstallation instructions\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eTechnical Specifications\u003c\/h3\u003e\n\u003cdiv style=\"overflow-x: auto; margin-bottom: 20px;\"\u003e\n  \u003ctable width=\"100%\" style=\"border-collapse: collapse; border: 1px solid #e0e0e0; font-size: 14px; min-width: 300px;\"\u003e\n    \u003ctr style=\"background-color: #f9f9f9;\"\u003e\n\u003cth style=\"padding:10px; text-align: left; border: 1px solid #e0e0e0;\"\u003eFitment\u003c\/th\u003e\n\u003ctd style=\"padding:10px; border: 1px solid #e0e0e0;\"\u003e2007-2008 Chevrolet Avalanche, Silverado\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003cth style=\"padding:10px; text-align: left; border: 1px solid #e0e0e0;\"\u003eEngine \/ Chassis\u003c\/th\u003e\n\u003ctd style=\"padding:10px; border: 1px solid #e0e0e0;\"\u003eLY2, LMG, LY5, LC9, L76 (Gen IV Small Block) \/ GMT900\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr style=\"background-color: #f9f9f9;\"\u003e\n\u003cth style=\"padding:10px; text-align: left; border: 1px solid #e0e0e0;\"\u003eStock Output\u003c\/th\u003e\n\u003ctd style=\"padding:10px; border: 1px solid #e0e0e0;\"\u003e295-367 hp \/ 305-375 lb-ft\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003cth style=\"padding:10px; text-align: left; border: 1px solid #e0e0e0;\"\u003eReplaces OEM Part #\u003c\/th\u003e\n\u003ctd style=\"padding:10px; border: 1px solid #e0e0e0;\"\u003eN\/A\u003c\/td\u003e\n\u003c\/tr\u003e\n  \u003c\/table\u003e\n\u003c\/div\u003e\n\n\u003ch3\u003eCompatibility\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e2007-2008 Chevrolet Avalanche 1500 (5.3L V8, 6.0L V8)\u003c\/li\u003e\n  \u003cli\u003e2007-2008 Chevrolet Silverado 1500 (New Body Style, 4.8L V8, 5.3L V8, 6.0L V8)\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eFrequently Asked Questions \u0026amp; Fitment Warnings\u003c\/h3\u003e\n\u003ch4\u003eDoes this fit the GMT900 Avalanche, Silverado?\u003c\/h4\u003e\n\u003cp\u003eYes, this is a direct fit for the 2007-2008 Chevrolet Avalanche and Silverado equipped with the \u003cstrong\u003eGen IV Small Block\u003c\/strong\u003e V8 engine. \u003cstrong\u003eNote: Will not fit 2007 \"Classic\" models (carryover GMT800 chassis) or vehicles equipped with mechanical engine-driven cooling fans.\u003c\/strong\u003e\u003c\/p\u003e\n\n\u003ch4\u003eWill this kit trigger a Check Engine Light or require an aftermarket tune?\u003c\/h4\u003e\n\u003cp\u003eNo, the intake incorporates factory MAF sensor housing dimensions to preserve proper fuel trims on the stock ECM without throwing a CEL.\u003c\/p\u003e\n\n\u003ch3\u003eThe Chevrolet Heavy-Duty Standard\u003c\/h3\u003e\n\u003cp\u003eEngineered to handle severe-duty hauling and highway towing, this high-flow system ensures consistent manifold air density under heavy engine loads while maintaining reliable filtration in dusty off-road environments.\u003c\/p\u003e","brand":"VelocityMax","offers":[{"title":"Default Title","offer_id":67907277390072,"sku":"DS-ES16GL016","price":251.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0800\/1290\/2648\/files\/cold-air-intake-for-chevrolet-avalanche-silverado-1500-2007-2008-4-8l-5-3l-6-0l-1.jpg?v=1793376287","url":"https:\/\/performancechiptuning.com\/fr\/products\/cold-air-intake-for-chevrolet-avalanche-silverado-1500-2007-2008-4-8l-5-3l-6-0l","provider":"Performance Chip Tuning","version":"1.0","type":"link"}
