This compact geometry produces turbulence and uneven cylinder distribution at lower RPMs. Furthermore, the direct mating of the cast intake creates thermal conduction that increases intake charge temperatures, decreasing overall volumetric efficiency under towing loads.\u003c\/p\u003e\n\n\u003ch3\u003eThe Engineering Solution\u003c\/h3\u003e\n\u003cp\u003eCNC-machined from billet 6061-T6 aluminum, this spacer expands plenum volume beneath the throttle bores to improve air column inertia. The engineered bore geometry guides intake air smoothly into the runners, enhancing fuel shear and droplet suspension from the dual injectors before combustion. Corrosion-resistant anodizing protects against fuel wash and heat degradation, providing a durable, leak-free mechanical seal using factory fastener torque specifications.\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;\"\u003e1988-1995 Chevrolet Blazer\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;\"\u003e4.3L LB4 V6, 5.7L LO5 V8 \/ GMT400, K5, S-10\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;\"\u003e160–210 hp \/ 235–300 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\u003e1988-1995 Chevrolet Blazer 4.3L V6 (TBI Engines)\u003c\/li\u003e\n  \u003cli\u003e1988-1995 Chevrolet Blazer 5.7L V8 (TBI Engines)\u003c\/li\u003e\n  \u003cli\u003eFits full-size K5\/GMT400 and S-10 Blazer models with standard dual-bore TBI\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eThe Chevrolet Durability Caliber\u003c\/h3\u003e\n\u003cp\u003eEngineered to handle the thermal demands and continuous vibration of severe truck service, this direct hardware upgrade bolsters off-idle towing grunt and crawling torque without requiring ECU modifications.\u003c\/p\u003e","brand":"VelocityMax","offers":[{"title":"Default Title","offer_id":50498975269112,"sku":"DS-EH29JFFDX","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-blazer-1988-1995-4-3l-5-7l-1.jpg?v=1789276008","url":"https:\/\/performancechiptuning.com\/es\/products\/throttle-body-spacer-for-chevrolet-blazer-1988-1995-4-3l-5-7l","provider":"Performance Chip Tuning","version":"1.0","type":"link"}
