Under immediate throttle tip-in, this blunt mating surface creates localized boundary layer separation and turbulence, which stalls intake charge velocity. The resulting drop in volumetric efficiency dulls off-idle throttle response, which is especially noticeable when crawling at low RPM or maneuvering steep technical inclines.\u003c\/p\u003e\n\n\u003ch3\u003eThe Engineering Solution\u003c\/h3\u003e\n\u003cp\u003ePrecision CNC-machined from solid 6061-T6 billet aluminum, this spacer spaces out the throttle valve to establish a laminar transition path into the manifold. The open-bore helical design stabilizes high-velocity airflow into the plenum chamber, smoothing intake pulses and building usable off-idle torque. Finished with a corrosion-resistant anodized coating, the assembly includes grade-304 stainless steel fasteners engineered to retain exact torque specs under severe thermal cycling without inducing intake vacuum leaks.\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;\"\u003e1991-2000 Jeep Cherokee\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;\"\u003eAMC 150 (2.5L) \u0026amp; AMC 242 (4.0L) \/ XJ Chassis\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;\"\u003e125-190 hp \/ 150-225 lb-ft (Engine Dependent)\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\u003e1991-2000 Jeep Cherokee (XJ) 2.5L I4 (AMC 150)\u003c\/li\u003e\n  \u003cli\u003e1991-2000 Jeep Cherokee (XJ) 4.0L I6 (AMC 242 \/ PowerTech)\u003c\/li\u003e\n  \u003cli\u003eFits Base, SE, Sport, Classic, Country, and Limited trims\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eThe Jeep Trail-Ready Standard\u003c\/h3\u003e\n\u003cp\u003eEngineered for high-vibration off-road duty, this solid hardware upgrade resists thermal heat soak and sustains mechanical clamping force across punishing low-range crawl operations.\u003c\/p\u003e","brand":"VelocityMax","offers":[{"title":"Default Title","offer_id":50498900164856,"sku":"DS-EK306JQ3R","price":49.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0800\/1290\/2648\/files\/throttle-body-spacer-for-jeep-cherokee-1991-2000-2-5l-4-0l-1.jpg?v=1789275103","url":"https:\/\/performancechiptuning.com\/products\/throttle-body-spacer-for-jeep-cherokee-1991-2000-2-5l-4-0l","provider":"Performance Chip Tuning","version":"1.0","type":"link"}
