AEM air intake 21-9227DS was designed for 2011 and 2012 Ram and Dodge Ram 2500 models with the 6.7 liter turbo diesel engine. The intake system uses the OEM air source to provide the coolest air possible for the engine. AEM inlet air temperature testing helped finalize a design that supplies near ambient temperature to the engine. Due to the proximity of the air intake to the turbocharger, an advanced polypropylene material with a high heat rating was utilized to keep incoming air cool. The custom airbox, of AEM air intake 21-9227DS, comes with an attached filter minder, which lets you know when the air filter requires service. The intake tube also provides for the factory MAF and IAT sensors. AEM research and development was able to produce an estimated gain of 8.5 horsepower and 19 ft lbs of torque at 2100 rpm.
