Increased power and fuel economy, while reducing exhaust gas temps and sooty, black smoke. Exclusive 5 inch bellows accommodates engine movement and prevents component damage.
The Banks Ram-Air Intake System delivers exceptional airflow and air density. Its large cotton gauze air filter requires fewer cleanings than competitive filters (stock's small paper filter is not reusable). With its giant 7-1/8" outlet, streamlined components and enclosed cold-air box that keeps hot engine air out of the intake, the Ram-Air flows up to 48% better than stock. Improves power and fuel economy; lowers exhaust gas temps and reduces black smoke. (An indicator of unburned fuel, black smoke is power you can see but not use!)
And Banks' unique 5" bellows accommodate engine movement, which prevents component damage and prolongs service life.
7 out of 8 “cold air” systems actually increase temperatures above stock levels at the turbo inlet!
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
Note: This illustration shows a stock LLY intake so yours may not be identical.
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 minimise the restriction and the pressure loss, air density will be preserved.
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.
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.

"Banks products never disappoint i know when I buy something its been tested and proven to work and perform as described. I noticed several degrees difference in my intake air temp when I switched to banks cold air intake 👍"
"Very easy to install. Truck has increased throttle response."
"Installed the Banks Ram Air as well as the Banks boost tubes when I got a cp3 swap. DEFINITE more power and significant increase in fuel mileage. Banks is the real deal"
"Installation was super easy with the digital instructions. Fitment is great. Love being able to hear more of the turbo spooning up."
"My stock air filter was struggling under heavy use, and this air box woke my truck back up!"
"High quality product and shipped in quality packaging. I had this installed along with a FASS system."
"The quality is great. Really like the extras that came in the box too."
"Great product. Easy install and very well built"
"Saved my alot of fuel highly recommend"
"Banks does not disappoint, I bought the ram air cold air intake for my 2003 Chevrolet Silverado 3500 Duramax and it was a very well thought out kit everything went together easy and the quality of the parts is outstanding! You can't go wrong with Banks."
