Engineered for high cylinder pressures, extended service life, and demanding duty cycles. The PACCAR MX-13 operates under extreme thermal and combustion loads. Traditional gray iron cylinder heads are pushed to their limits under modern emissions-era operating conditions.\u003c\/p\u003e\n\u003ch3\u003ePDI’s CGI MX-13 Cylinder Head is engineered to exceed those limits.\u003c\/h3\u003e\n\u003cp\u003eBy combining Compacted Graphite Iron metallurgy with Inconel intake and exhaust valves, this cylinder head delivers improved resistance to cracking, valve failure, and heat-related distortion. It is ideal for heavy-haul, vocational, and performance-focused rebuilds where durability and uptime matter most.\u003c\/p\u003e\n\u003ch3\u003eKey Features and Benefits\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eCompacted Graphite Iron (CGI) Casting\u003c\/strong\u003e\u003cbr\u003eStronger than traditional gray iron with increased fatigue resistance\u003cbr\u003eDesigned to handle higher cylinder pressures without cracking\u003cbr\u003eImproved thermal stability under sustained exhaust gas temperatures\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInconel Intake and Exhaust Valves\u003c\/strong\u003e\u003cbr\u003eExceptional resistance to heat and corrosion\u003cbr\u003eDesigned for modern emissions-era exhaust temperatures\u003cbr\u003eExtended valve life in high-load and severe-duty applications\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePrecision Machined for Exact Fit\u003c\/strong\u003e\u003cbr\u003eOEM-spec oil, coolant, and combustion passages\u003cbr\u003eDesigned for drop-in compatibility on PACCAR MX-13 platforms\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePDI Quality Control Standards\u003c\/strong\u003e\u003cbr\u003eMulti-stage inspection process\u003cbr\u003eFlatness, valve seat concentricity, and pressure testing performed prior to release\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eApplications\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003ePaccar MX13 EPA13 Engines\u003cbr\u003e\n\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ctable width=\"100%\"\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003e OEM Cross Reference\u003c\/td\u003e\n\u003ctd\u003e 1904700, 2115424, 2128155, 2146346, 2184938, 2190203, 2396047\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e","brand":"Performance Diesel Inc","offers":[{"title":"Default Title","offer_id":51175321272626,"sku":"144007175424","price":4895.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0914\/6571\/1922\/files\/144007175424_-_PDI_Paccar_MX13_Cylinder_Head_2.webp?v=1779224565","url":"https:\/\/richardsoncorp.net\/products\/pdi-big-boss-detroit-dd15-cylinder-head-copy","provider":"RichardsonCorp","version":"1.0","type":"link"}
