It is engineered to move the MAP sensor farther from hot EGR flow and to provide a more protective sensor shroud for a more durable repair on Ram 1500, Jeep Grand Cherokee, and Jeep Wrangler diesel applications.\u003c\/p\u003e\u003ch2\u003eKey Features\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003ePlastic intake manifold with black finish\u003c\/li\u003e\n\u003cli\u003eOE FIX design for EcoDiesel intake system repairs\u003c\/li\u003e\n\u003cli\u003eDeeper sensor shroud helps shield the MAP sensor from hot EGR gases\u003c\/li\u003e\n\u003cli\u003eBuilt to redirect soot and heat through the intake path more effectively\u003c\/li\u003e\n\u003cli\u003eIncludes gasket or seal\u003c\/li\u003e\n\u003cli\u003eEGR ready and street legal\u003c\/li\u003e\n\u003cli\u003eStandard replacement grade\u003c\/li\u003e\n\u003cli\u003eDesigned to work with Dorman OE Solutions intake manifold gaskets only\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eDetailed Description\u003c\/h2\u003e\u003cp\u003eThis Dorman intake manifold addresses a known failure pattern on Chrysler EcoDiesel V6 engines where soot, heat, and EGR contamination can build up inside the manifold and affect runner operation. Over time, trapped heat can warp the manifold, damage the runners, and foul the MAP sensor or IMRC system. Dorman 615-311 uses an updated OE FIX design that places the sensor farther out of the direct path of hot exhaust gas and adds a deeper protective skirt around the sensor shroud. It is a practical replacement for Ram 1500, Jeep Grand Cherokee, and Jeep Wrangler diesel models when the original manifold has been compromised by soot and heat exposure.\u003c\/p\u003e\u003cp\u003eThis part cross-references Chrysler OE numbers 68211167AA and 68211167AB for the same application.\u003c\/p\u003e\u003ch2\u003eWhat It Helps Address\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eLoss of power caused by intake manifold soot buildup\u003c\/li\u003e\n\u003cli\u003eSmoke and burning odor from heat-damaged intake components\u003c\/li\u003e\n\u003cli\u003eIMRC system fouling from soot and residue\u003c\/li\u003e\n\u003cli\u003eWarped or leaking manifold surfaces from trapped heat\u003c\/li\u003e\n\u003cli\u003eMAP sensor damage from hot EGR gas exposure\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eInstallation Notes and Tips\u003c\/h2\u003e\u003cp\u003eCompatible With 2014-2018 Ram 1500, upper; 2019 Ram 1500 Classic, upper; 2020-2023 Ram 1500, upper; 2014-2021 Jeep Grand Cherokee, upper; and 2020-2023 Jeep Wrangler, upper.
