Banks Ram-Air® Intake System

Passes the test. Again and again.
Others build and ship without testing. Not Banks. Our Ram-Air Intakes start out as CAD software prototypes and are put through flow simulations. The design is refined until the simulation shows optimal performance. Then a hardware prototype is made and the design is validated on a flowbench. After that comes dyno testing and on-vehicle testing. It takes a superior design to pass all those tests!

Filter on a stick: a joke that’s not funny.
A filter on a stick is a bad joke. It’s wide-open to hot underhood engine air, and there’s no power in hot air! Ram-Air houses a giant lifetime filter in an enclosed cold-air box, which inhales cool, dense outside air—more than Banks’ competitors and up to 57% more than stock—for more power and mileage, lower EGTs and less smoke. And it's designed to not cause fault or error codes.

Bellows, too? Very exclusive.
Banks Ram-Air is the only aftermarket intake with bellows. This accommodates engine movement and prevents component damage for longer service life. The optional high-flow Super-Scoop is another Banks exclusive!

Note: This illustration shows a stock LLY intake so yours may not be identical.

Available separately: new Super-Scoop optimizes the Ram-Air Intake's efficiency and power!


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.

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


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.

Data Acquisition

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 air 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.

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.

LB7 Ram-Air Intake System: I noticed a big difference...

2009-12-10

Good Morning Richard,
First let me thank you and BANKS POWER for the RAM AIR system I purchased for my 2001 GMC Sierra 2500 HD diesel. I finally had the time to install it last Saturday. The installation went well and was easy to do. I noticed a big difference right away when I started my truck. No smoke, smoother / quicker acceleration. I had to go on a long trip the following day and did notice better mileage. All of BANKS claims were true. I am very happy and impressed.

Thank you and thank BANKS POWER.

LB7 Ram-Air & Monster Exhaust: I was shocked...

2010-08-12

Hi Frank, I just wanted to let you know how very pleased I am with your help and Banks' products. I've been very busy, working long hours but I wanted to hold still long enough to say Thanks. I was a little uneasy about hooking up this equipment on my own but, the way Banks packaged everything was a pleasant surprise. Frank, I was shocked when I finished installation of Ram Air System & Monster Exhaust I thought to myself, This wasn't painful at all! The way the exhaust pins slid into Chevy hangers was a breeze! I'm saving all over again now so I can get some more of Banks' goodies! Best Regards and thanks again. One more note: I was told delivery would be 6 to 10 days. Well, I got my equip delivered to my house in 5!!!!! BANKS IS BEST

LB7 Exhaust Brake, Ram-Air and Monster Exhaust: Noticed some very positive things...

2010-08-12

Hey Frank! I just wanted to give A SHOUT OUT! to my favorite Banks guy, and let you know, that I am very happy with my Banks equipment. I got it installed yesterday and noticed some very positive things, such as more power, cooler temp, great sound, and tremendous performance, from the brake. I also want to recommend Rocky's Tuff Trucks, 345 E. Broadway, Gallitin, Tenn, for his great and professional installation of your equipment. He will make a great installer for your product. Please include him on your list of very qualified companies, that do a great job. I look forward to a long term relationship with both Banks, and Rocky's Tuff Truck. Thanks for both of you guys help.

Frank, I just wanted you to know that once again, I received my order in great time and packaged very well! Your S&R Dept do very good work and I commend them for this.

I know you must speak to a lot of people every work day and you may not remember but, I told you in the past that I wasn't very mechanically inclined but I do like to change my own oil and easy tasks like that.

Well, the instructions that came with all my parts were so well detailed that after reading over all of this, I thought to myself: I think I can do this!
I gathered all my tools and began. I'm so excited I can't hardly believe it! I've got it all hooked up! YES!!!!
I received it all on a Friday ( Good shipping to S. Louisiana in 5 days! Pretty cool.
Saturday morning I began. Now you've got to realize, I'm kinda slow, not too sure of myself, had to go back over papers and read carefully,
trying to prevent any mistakes. You know the drill, pulled right front wheel, drilled & tapped exhaust manifold for EGT probe.
Went to work on Big-Head Actuator. Wrapped that up and tackled Six Gun Tuner. Feeling pretty good, Frank!
Once I got the IQ mounted and wired, I thought, well, I'm going to re-attach battery cables, say a prayer & awaken the beast!

I might be sleeping in the shed but, I'm a happy camper!

Thank you!

A satisfied customer and your pal

Best Regards:
