This short runner interface creates boundary-layer turbulence and uneven charge distribution at initial throttle tip-in. Furthermore, rapid heat soak from the cast cylinder head conducts directly into the throttle assembly, thinning intake air density and reducing low-rpm scavenging efficiency.\u003c\/p\u003e\n\n\u003ch3\u003eThe Engineering Solution\u003c\/h3\u003e\n\u003cp\u003eCNC-machined from aircraft-grade 6061-T6 billet aluminum, this spacer lengthens the intake tract to smooth air transition from the throttle bore into the manifold runners. The specialized internal geometry stabilizes high-velocity airflow, aiding cylinder filling before the intake valve closes. Packaged with corrosion-resistant 304 stainless steel hardware, it guarantees a rigid, leak-free seal that resists thermal degradation and underhood vibrational stress.\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;\"\u003e1991-1992 Jeep Comanche\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 HO (4.0L) \/ MJ Platform\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;\"\u003e130 hp \/ 149 lb-ft (2.5L) | 190 hp \/ 225 lb-ft (4.0L)\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\u003e1991-1992 Jeep Comanche (MJ) 2.5L I4 (AMC 150)\u003c\/li\u003e\n  \u003cli\u003e1991-1992 Jeep Comanche (MJ) 4.0L I6 (AMC 242 High Output)\u003c\/li\u003e\n  \u003cli\u003eDirect fitment for Base, Pioneer, and Eliminator trim packages\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eThe Jeep Trail-Duty Standard\u003c\/h3\u003e\n\u003cp\u003eEngineered to handle severe trail washboards and crawl-ratio lugging, this solid-metal intake modification delivers mechanical durability with zero vacuum failure points or recalibration requirements.\u003c\/p\u003e","brand":"VelocityMax","offers":[{"title":"Default Title","offer_id":50498931327224,"sku":"DS-E3K91ZYNY","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-comanche-1991-1992-2-5l-4-0l-1.jpg?v=1789275165","url":"https:\/\/performancechiptuning.com\/products\/throttle-body-spacer-for-jeep-comanche-1991-1992-2-5l-4-0l","provider":"Performance Chip Tuning","version":"1.0","type":"link"}
