Banks' revolutionary Ram-Air Intake System offers the reliability and durability of a factory intake yet delivers astonishing airflow. It flows up to 64% better than stock and outflows Volant and AIRAID, thanks in part to the Ram-Air's huge filter area (fewer filter cleanings!), giant outlet, and the complete air filter housing with large side & bottom inlets. Banks Ram-Air collects & directs more power-producing cool, dense air to the engine, lowering EGTs and smoke and improving fuel economy, too! The lifetime 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. This prevents component damage and promotes reliable service life.
6 out of 7 “cold air” systems provide LESS air density to the turbo inlet than the stock system! That sucks for our competitors, because air density is the key to better performance. MORE DENSITY = MORE MPG AND HP.
It’s good to be dense, all right. Check out our density ad for an informative look at intake airflow, air temperature and air density, and how they all come together in the Banks Ram-Air Intake. Bankspower.com/density ad
Testing so good, it’s patented! Banks sets uncompromisingly high standards for testing. In fact, we were awarded an Engine Performance Evaluation patent from the United States Patent and Trademark Office. Check it out: Engine Performance Evaluation: US Patent # 7,254,477
We measured each intake’s effect on air density at the turbo compressor inlet. 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.
A 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.
Testing 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.
Vehicle 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.
All intake filtering systems will have some effect of diminished air density from ambient, including stock. The purpose of this evaluation is to compare this effect in relationship to the stock system. A replacement intake system is only valuable and effective if the intake air density percentage vs. ambient is greater than the air density percentage offered by the stock system.
All data presented assumes an ambient temperature of 77°F and ambient pressure of 29.24 inches of mercury, per SAE standards.

I just wanted to drop you guys (and gals) a letter stating how much I appreciate your products. I just spent the afternoon taking a competitor's product off my truck because it did not work as claimed and in fact made my vehicle unpleasant to drive. I have several Banks items on my truck and they all have fit perfectly, worked as claimed and have never caused me a minute of dissatisfaction. I will always buy from your company in the future for any performance product related to my vehicle. Trust me when I say I just wasted $400 to learn that I should've stuck with a brand I know and trust. Keep up the good work.

Adding a cold air intake is just about the easiest thing you can do to add performance to your truck, and Banks Power has the best intake you can get. From the TV show Trucks! back in April 2006.
