Under low-RPM towing loads and tip-in acceleration, this restricted entry induces localized charge turbulence and fuel pooling. This dampens manifold vacuum signal recovery, causing sluggish off-idle throttle response and uneven air-fuel distribution across the intake runners.\u003c\/p\u003e\n\n\u003ch3\u003eThe Engineering Solution\u003c\/h3\u003e\n\u003cp\u003eCNC-machined from 6061-T6 billet aluminum, this spacer extends runner length and expands plenum volume directly beneath the TBI baseplate. The bore design accelerates boundary-layer airflow to promote finer fuel atomization before entering the manifold runners. Finished in a corrosion-resistant anodized coating, the rigid aluminum spacer resists warping and intake vacuum leaks across high thermal cycles.\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;\"\u003e1992-1995 GMC Suburban\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;\"\u003e5.7L LO5 TBI V8 \/ GMT400\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;\"\u003e210 hp \/ 300 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\u003e1992-1995 GMC C1500 Suburban 5.7L V8 (LO5)\u003c\/li\u003e\n  \u003cli\u003e1992-1995 GMC K1500 Suburban 5.7L V8 (LO5)\u003c\/li\u003e\n  \u003cli\u003e1992-1995 GMC C2500 Suburban 5.7L V8 (LO5)\u003c\/li\u003e\n  \u003cli\u003e1992-1995 GMC K2500 Suburban 5.7L V8 (LO5)\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eThe GMC Workhorse Caliber\u003c\/h3\u003e\n\u003cp\u003eEngineered for heavy GMT400 utility, this mechanical spacer supports immediate off-idle torque delivery required for towing and hauling, without requiring ECU recalibration.\u003c\/p\u003e","brand":"VelocityMax","offers":[{"title":"Default Title","offer_id":50498978644216,"sku":"DS-EBBS6H7JD","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-gmc-suburban-1992-1995-5-7l-1.jpg?v=1789276163","url":"https:\/\/performancechiptuning.com\/products\/throttle-body-spacer-for-gmc-suburban-1992-1995-5-7l","provider":"Performance Chip Tuning","version":"1.0","type":"link"}
