On 2004-2006 drive-by-wire 4.8L and 5.3L platforms, this restricted entry induces boundary-layer turbulence during sudden throttle tip-in. The resultant flow disruption causes sluggish acceleration, delayed throttle response under heavy towing loads, and inefficient cylinder filling in the sub-3,000 RPM range where these full-size SUVs operate most frequently.\u003c\/p\u003e\n\n\u003ch3\u003eThe Engineering Solution\u003c\/h3\u003e\n\u003cp\u003eCNC-machined from solid 6061-T6 aircraft-grade billet aluminum, this spacer features an anodized protective finish that resists thermal cycling and underhood oxidation. Its optimized open-bore helical internal profile channels and stabilizes air entering the manifold plenum, minimizing shear-layer separation and accelerating incoming air charge velocity. Supplied with corrosion-resistant 304 stainless steel hardware, it installs cleanly between the factory throttle body and intake without requiring ECU recalibration, wiring modifications, or vacuum re-routing.\u003c\/p\u003e\n\n\u003ch3\u003eTechnical Specifications\u003c\/h3\u003e\n\u003ctable width=\"100%\" style=\"border-collapse: collapse; border: 1px solid #e0e0e0; font-size: 14px;\"\u003e\n  \u003ctr style=\"background-color: #f9f9f9;\"\u003e\n\u003ctd style=\"padding:8px;\"\u003e\u003cstrong\u003eFitment\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd style=\"padding:8px;\"\u003e2004-2006 Chevrolet Tahoe\u003c\/td\u003e\n\u003c\/tr\u003e\n  \u003ctr\u003e\n\u003ctd style=\"padding:8px;\"\u003e\u003cstrong\u003eEngine \/ Chassis\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd style=\"padding:8px;\"\u003e4.8L LR4, 5.3L LM7\/L59 \/ GMT800\u003c\/td\u003e\n\u003c\/tr\u003e\n  \u003ctr style=\"background-color: #f9f9f9;\"\u003e\n\u003ctd style=\"padding:8px;\"\u003e\u003cstrong\u003eStock Output\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd style=\"padding:8px;\"\u003e275-295 hp \/ 290-335 lb-ft (Approx)\u003c\/td\u003e\n\u003c\/tr\u003e\n  \u003ctr\u003e\n\u003ctd style=\"padding:8px;\"\u003e\u003cstrong\u003ePart Number\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd style=\"padding:8px;\"\u003eN\/A\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e\n\n\u003ch3\u003eCompatibility\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e2004-2006 Chevrolet Tahoe LS 4.8L V8 (LR4)\u003c\/li\u003e\n  \u003cli\u003e2004-2006 Chevrolet Tahoe LS 5.3L V8 (LM7 \/ L59)\u003c\/li\u003e\n  \u003cli\u003e2004-2006 Chevrolet Tahoe LT 5.3L V8 (LM7 \/ L59)\u003c\/li\u003e\n  \u003cli\u003e2004-2006 Chevrolet Tahoe Z71 5.3L V8 (LM7 \/ L59)\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eThe Chevrolet Truck Standard\u003c\/h3\u003e\n\u003cp\u003eBuilt to handle the thermal demands and continuous mechanical stresses of heavy towing, trail work, and high-mileage utility, this billet spacer delivers reliable mechanical flow optimization without triggering diagnostic trouble codes or vacuum faults.\u003c\/p\u003e","brand":"VelocityMax","offers":[{"title":"Default Title","offer_id":50498889253112,"sku":"DS-E40WBUK9L","price":63.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0800\/1290\/2648\/files\/throttle-body-spacer-for-chevrolet-tahoe-2004-2006-4-8l-5-3l-1.jpg?v=1789274798","url":"https:\/\/performancechiptuning.com\/fr\/products\/throttle-body-spacer-for-chevrolet-tahoe-2004-2006-4-8l-5-3l","provider":"Performance Chip Tuning","version":"1.0","type":"link"}
