This intake manifold plenum grid heater plate is machined from aluminum and measures 1/2" thick, designed as a direct-fit replacement for the factory-style grid heater on 2008-2024 Dodge Ram with the 6.7L Cummins diesel engine. The factory grid heater sits directly in the intake plenum and acts as a massive restriction, and this machined plate allows a massive volume of cooler, denser air into the engine. Built for heavy-duty diesel use, this plate is designed for reliable sealing, long-term durability, and strength under demanding conditions in towing, hauling, daily driving, and performance-minded builds.
