This tight clearance induces boundary-layer turbulence and uneven fuel atomization before the charge enters the intake runners, dampening throttle response and choking off low-RPM torque when operating under towing or heavy payload conditions.\u003c\/p\u003e\n\n\u003ch3\u003eThe Engineering Solution\u003c\/h3\u003e\n\u003cp\u003ePrecision CNC-machined from 6061-T6 billet aluminum, this spacer adds effective plenum volume to stabilize incoming air charges. The specialized internal bore design accelerates airflow to enhance fuel-air mixing without disturbing critical manifold vacuum or factory sensors. Finished with a corrosion-resistant anodized coating, it withstands engine bay thermal cycling while preventing vacuum leaks under sustained manifold vacuum.\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 GMC C\/K Trucks\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, 5.0L L03, 5.7L L05 \/ 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;\"\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 GMC C1500 \/ K1500 (4.3L V6, 5.0L V8, 5.7L V8 TBI)\u003c\/li\u003e\n  \u003cli\u003e1988-1995 GMC C2500 \/ K2500 (4.3L V6, 5.0L V8, 5.7L V8 TBI)\u003c\/li\u003e\n  \u003cli\u003e1988-1995 GMC C3500 \/ K3500 (5.7L V8 TBI)\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eThe GMC Workhorse Caliber\u003c\/h3\u003e\n\u003cp\u003eEngineered to handle severe towing loads and off-road work, this mechanical upgrade delivers crisp throttle pickup and reliable low-end pulling force without requiring computer recalibration or electrical tuning.\u003c\/p\u003e","brand":"VelocityMax","offers":[{"title":"Default Title","offer_id":50498937520376,"sku":"DS-EAHUI0PTV","price":63.95,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0800\/1290\/2648\/files\/throttle-body-spacer-for-gmc-c-k-trucks-1988-1995-4-3l-5-0l-5-7l-1.jpg?v=1789275255","url":"https:\/\/performancechiptuning.com\/products\/throttle-body-spacer-for-gmc-c-k-trucks-1988-1995-4-3l-5-0l-5-7l","provider":"Performance Chip Tuning","version":"1.0","type":"link"}
