---tab Description--- Description If you drive a 6.7L Cummins, you know the factory grid heater is a ticking time bomb. The retaining bolt is notorious for breaking off and dropping directly into cylinder #6, causing catastrophic engine damage that costs thousands to repair. While standard "grid heater deletes" remove this threat, they leave you with brutal cold-weather starts, thick white smoke, and a sluggish engine on winter mornings. The ALL-NEW Upgraded SPELAB 3.5" Intake Manifold is the Ultimate Solution.We took our best-selling intake manifold and made two massive engineering upgrades based on driver feedback: Premium Material Upgrade We upgraded the construction from 201 to premium T-304 Stainless Steel, maximizing corrosion resistance and structural strength under extreme heat and boost. True "Dent-Free" Airflow Older designs (and competitor models) feature a crushed "dent" in the pipe to clear the factory fuel line. We eliminated that dent. Our new manifold is perfectly round for 100% unrestricted airflow. By integrating a high-wattage heating coil directly into this massive, perfectly smooth 3.5" manifold, you get the ultimate trifecta: zero risk of a dropped bolt, immediate cold-weather starts, and a massive rush of unrestricted airflow for faster turbo spooling and lower EGTs. Note: If installing this manifold with a Grid Heater Delete Plate, an IAT Sensor Extension Harness is required. The factory wiring is too short for the new sensor position. Ensure a perfect, plug-and-play fit by adding the harness to your order. Fitment 2007-2024 Dodge Ram 2500/3500 6.7L Diesel, doesn't fit cab and chassis. Key Features Integrated High-Efficiency Heating ElementProvides reliable, fast startups in cold climates, reducing engine wear and eliminating the excessive white smoke associated with cold diesel engines. Say goodbye to the performance compromise of a grid heater delete. Massive 3.5" High-Flow DesignMandrel-bent T-304 stainless steel construction dramatically increases airflow compared to the restrictive stock manifold. This results in quicker turbo spool, lower EGTs (Exhaust Gas Temperatures), and significant gains in horsepower and torque. Superior Durability & ConstructionFabricated from premium T-304 stainless steel for exceptional strength, corrosion resistance, and heat dissipation. Precision TIG welding ensures a leak-proof seal and long-lasting performance under the most demanding conditions. Direct Bolt-On InstallationEngineered to utilize factory mounting points for a straightforward installation. The kit includes multiple NPT ports for easy connection of boost gauges, sensors, or water-methanol injection systems. Prevent the Notorious Grid Heater Bolt Failure The factory grid heater design on the 6.7L Dodge Ram engine poses a significant, well-documented risk. The retaining bolt and nut for the heating element are known to eventually fail, break off, and drop directly into the intake, leading to catastrophic and costly internal...
