Specifications

Testing, testing & more testing.

Banks Ram-Air Intake Systems are tested and proven. They start out as CAD software prototypes and are put through flow simulations. After a hardware prototype is made, it's tested on a flowbench. Then it's tested on the vehicle. And finally, Banks' density-tests the Ram-Air against stock and many competitors.

Proven design. Proven performance.

Thanks to its enclosed cold-air housing, huge inlet, giant dome-shaped filter and streamlined design, Banks Ram-Air Intake maximizes the flow of cool, dense air to the engine for greater power and fuel economy. It flows 35% better than stock. And delivers greater air density to the turbo's inlet than the stock system and every competitor tested!

It's all about density.

And Banks Ram-Air Intakes deliver. The harder you work your truck, the more Banks Ram-Air Intake improves power and fuel economy!

Longer service life, too.

An aftermarket exclusive: with 5" bellows, Banks Ram-Air accommodates engine movement, which protects the components and extends service life. What's more, Ram-Air is designed to not cause fault or error codes.

Why It's Better

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.

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

Overview Summary

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.

Test Setup

A 2006 Chevrolet 2500HD, 4 wheel drive, with a crew cab, six foot bed 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.

Bottom Line

Why on earth would anyone pay money for a product that kills power and mileage? It’s all about density — and Banks Ram-Air delivers.

NEW FILTER OPTIONS! Choose from the traditional red, oiled filter or the all-new black, dry filter. Plus, you can even get an extra layer of filtration protection by adding a pre-filter to your order.

Dad's truck

Dad's 2500HD I inherited my dad's 2006 GMC 2500HD, and it is special to me and my family because it was my father's. I'm getting ready to retire and wanted to get the truck ready for the big retirement move. Friends highly recommend Banks products for a long list of reasons; performance, quality, fitments,...

Excellent!

Very well built! All parts included and more than you’d expect like the tamperproof torx bit! Watched intake air temp on my scanner and was only 5 degrees warmer than ambient air temperature. Every degree counts during Florida summers! Only problem I had was my truck had the turbo mouthpiece off a lbz...

More Banks goodies for my truck

Initial install didn’t go as planned on my 14 LML, on my truck the air box sat lower and didn’t align with the fender opening. A quick call to tech support and they determined that the spacers that are included with the kits for the 15’s and 16’s would fix the problem and raise the box up. Received spacers...

Huge improvement over stock!

Really impressed that is an actual functioning cold air intake. I immediately saw an average of 15 degree Fahrenheit drop in intake air manifold temperature compared to the stock air intake assembly. Good job Mr. Gale Banks! Thank you sir. I’m seeing other improvements as well, acceleration is better...

Banks are engine people. In a world of companies making disparate parts, Banks engineers the entire engine, not just its components. The proof of Banks’ expertise is its list of national championships and world records as well as the biggest military engine contract of the century. Of all the possible options, the U.S. military chose the Banks D866T engine for its high performance and durability. With over 66 years of breakthroughs and patents in high-performance gas and diesel engine development —including turbocharging and drivetrain, Banks has no rival.
