Banks Ram-Air collects \u0026amp; directs more power-producing cool, dense air to the engine, lowering EGTs and smoke and improving fuel economy, too! The cotton gauze filter traps the most dirt and debris. And Ram-Air is the only aftermarket intake with 4-1\/2\" bellows to accommodate engine movement.

Intake temperatures will generally be higher than ambient conditions, but the more the system can duct cool air to the filter and preserve the cool temperature as the air is ducted to the turbo, the higher the air density will be. In addition, there will commonly be a pressure drop as air travels through the filter and the ducting due to any restriction that is introduced. If the design of the system can minimize the restriction and the pressure loss, air density will be preserved.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003ch2\u003eTest Setup\u003c\/h2\u003e\n\u003cdiv\u003e\n\u003cp\u003eA 2004 Dodge Ram 2500 4X4 Quad Cab Long Bed with the Cummins 5.9L engine and automatic transmission was used as the test vehicle. A data acquisition system was used to measure vehicle speed via GPS, along with multiple temperature thermistors and extremely accurate pressure transducers. The total vehicle weight was approximately 19,000 lbs. Tests were run in 2WD.\u003c\/p\u003e\n\u003cp\u003eTesting was conducted on a moderate hill on the northbound CA-57 in the city of Pomona. Speed was maintained at 45 MPH until the vehicle was adjacent to a pre-determined start point on the road. At that point, the accelerator was fully depressed and the vehicle was allowed to accelerate while climbing the hill. Test data was observed at the same vehicle speed in all cases, with the engine at 2800 RPM, the point of peak engine power. This data point occurred between 60 and 90 seconds into the run—sufficient time to allow the engine to reach a stabilized operating condition.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003chr class=\"description__hr\"\u003e\n\u003ch2\u003eData Acquisition\u003c\/h2\u003e\n\u003cdiv\u003e\n\u003cp\u003eVehicle Speed, Engine RPM and Accelerator Pedal Position were logged to determine the load conditions and speeds. Temperature was measured using thermistors for increased accuracy. They were mounted to measure ambient temperature as well as temperatures at the filter and compressor inlets. Pressure transducers were used to measure pressure in the same locations. The intake system effect on air density was evaluated by comparing the temperature and pressure of the ambient air condition with the temperature and pressure of the air at the turbo compressor inlet.\u003c\/p\u003e\n\u003cspan\u003eAll intake filtering systems will have some effect of diminished air density from ambient, including stock.
