Frequently Asked Questions: Ram-Air Intakes

Will a Ram-Air intake void my warranty?

The Ram Air Intake is a high flow aftermarket intake. Treat the intake as you would with altering the truck’s suspension, wheels, or tires. Most dealerships understand accessories like upgraded suspension systems are harmless, however, some dealers are not as forgiving. Always check with your service advisor prior to dropping off your truck. Are they ok with aftermarket accessories? If they don’t give you a concrete answer, call another dealership or service center. There are plenty of aftermarket-friendly dealerships.

What is the difference between oiled and dry filters?

An oiled filter typically uses fewer layers of filter media because the oil works to capture debris while a dry filter requires additional layers in order to capture the same amount of debris. While both styles capture a similar amount of debris, the oiled filter will flow about 3% better.

Should I buy an oiled or dry filter?

We recommend oiled filters for drivers who find themselves on paved roads the majority of the time. Dry filters are especially useful in dusty environments. Oiled filters are good at capturing dust. And, in an off-road environment, they can be “too good” at capturing dust, requiring frequent cleanings. If you do find yourself in a dusty environment, we also suggest a pre-filter to help extend the duration between needed cleanings.

How long is the service life between cleanings for the filters? Can they be cleaned?

Both oiled and dry filters can be cleaned. Dry filters can go up to about 20,000, whereas the oiled can go up to 30,000 miles before needing to be cleaned.

Where do I find replacement filters?

I don’t see an intake for my vehicle why?

For all trucks ’18+ engines, as required by the EPA/CARB, they now have a Hydrocarbon Trap or HCT filter built in the intake tract to prevent gases from leaking out. Sometimes we cannot overcome this piece of emission equipment and will either not offer an intake at all or one that is 50 state CARB approved.

How do you protect against water for Jeep intakes?

We combat water intrusion in several ways:

1. Jeep rates both the Gladiator and Wrangler for 30 inches of water fording. The opening for the intake is above this, tucked in the engine compartment. There is no direct path from the grill to the intake housing compartment. 

2. Our intake housing is designed with a water dump in mind. So even if it was to get in, it will not harm the engine. It will drain out

3. We have a small drain build into the housing to prevent water from being sucked up and causing hydrolock. Additionally, there is a three defense design against water intrusion by having a smaller, second drain near the filter coupler sleeve. 

If the intake doesn’t add power, what’s the point of buying one?

Your engine needs to make power regardless of how fast the vehicle is moving. Any opportunity to draw in cooler, denser air will always provide more power and increased longevity. The Banks Ram-Air is far less restrictive, and always outflows stock. A much larger surface area on the filter means increased dust collection and more miles between cleanings. More importantly, as your stock filter is becoming clogged thanks to its tight pleats and deep valleys, the Banks filter element will still be flowing freely longer thanks to its much larger dust capacity.

What is the difference between the Resonator Delete and a Cold Air intake?

Upgrading from the stock intake airbox to either a cold air intake or a resonator delete is always a good option. The resonator delete improves airflow, but by a small amount. These parts are used for a little increase in sound, airflow, and engine dressing while using the stock airbox. A resonator delete is great for those who wish to retain their stock airbox yet add a little spice under the hood.

A full cold air intake system is the best option because it is designed to maximize airflow and manifold air density. And, in most cases, it deletes the stock resonator, providing for more turbo sound. Everything from the intake airbox to the air filter and tube work together to not only lower the intake temperature but also to force as much cold dense air into the engine as possible.

What models and years is the Super-Scoop available for? How come I can’t find one for my truck?

2011-2014 Chevy/GMC 2500/3500 6.6L Duramax, and 2011-2013 Gas

Why do you offer pre-filters for some applications and not for others?

Some filters have the option for a pre-filter, those that do not are too big for a pre-filter. And many of our newer intakes like 2017-19 Duramax L5P and 2013-18 RAM 6.7L are designed so that the filter element moves slightly within the airbox as the engine rocks back and forth under load. A pre-filter would rip and tear if sandwiched between the filter element and airbox.


How do I clean an oiled filter?

PRE-CLEANING – Tap the element to dislodge any large embedded dirt, then gently brush with a soft bristle brush. If complete cleaning is not practical at this time, re-oil the element and reinstall it in your vehicle.

SPRAY-ON CLEANING – Spray air-filter cleaner liberally onto the entire element and let soak for 10 minutes, but do not allow the filter to dry.

PAN CLEANING – Large air-filter elements can be rolled or soaked in a shallow pan of air-filter cleaner. Remove immediately and allow it to soak for approximately 10 minutes.

  • NEVER use a brush to clean or scrub the filter, the bristles from a brush can rip and tear the filtering material. The air filter cleaning solution is a powerful degreaser and will break up even the most hardened, stubborn dirt particles with no scrubbing necessary.
  • NEVER use gasoline, steam, acid solutions, strong detergents, or cleaning solvents to clean the filter element. All of these can cause harm to the filter media as well as SHRINK and HARDEN the rubber end caps.

RINSING – Rinse off the element with low-pressure water. Tap water is okay. Always flush from the clean side to the dirty side. Rinsing removes the dirt and does not drive it into the filter.

  • NEVER use a hose attachment like a sprayer nozzle or a pressure washer. Using a high-pressure sprayer will have the same effect as a brush or air compressor and ruin the filter element.

DRYING – Always dry naturally. After rinsing, shake off all excess water and let the element dry naturally.

  • DO NOT try and speed up the process by using compressed air, oven baking or a blow dryer, this will damage the filter and ruin the material.
  • AEROSOL OILING – After cleaning the air filter, always re-oil before using. Spray air filter oil down into each pleat with one pass per pleat. Wait 10 minutes and re-oil any white spots still showing.
  • OILING HINTS Never use a Banks Ram-Air oiled filter without oil (the filter will not stop the dirt without the oil). Use only air filter oil. Air-filter oil is a compound of oil blended with unique polymers to form a very efficient tack barrier. Red dye is added to show just where you have applied the oil. Eventually, the red color will fade, but the oil will remain and filter the air.
  • NEVER Use Automatic Transmission Fluid Motor Oil, Diesel Fuel, WD40, LPS, or other light-weight oils.

REINSTALL – Reinstall your Banks Ram-Air filter element with proper care. Make sure the filter element seats properly in the filter case. Install the cover making sure it’s in the right position. Tighten all the nuts, bolts, screws, or clips to factory specifications.


How Do I clean a dry filter?

PRE-CLEANING – Carefully tap the air filter element to dislodge any large embedded dirt or debris.

CLEANING – Spray an appropriate AIR-FILTER CLEANER SOLUTION liberally onto both sides of the entire filter element with the majority applied to the dirty side. Soak for 10 minutes. Do not allow the AIR-FILTER CLEANER SOLUTION to dry on the air filter.

  • NEVER use a brush to clean or scrub the filter, the bristles from a brush can rip and tear the filtering material. The air filter cleaning solution is a powerful degreaser and will break up even the most hardened, stubborn dirt particles with no scrubbing necessary.
  • NEVER use gasoline, steam, acid solutions, strong detergents, high-pressure nozzles, or cleaning solvents to clean the filter element. All of these can cause harm to the filter media as well as SHRINK and HARDEN the rubber end caps.

RINSING – Rinse the filter element with cool or warm (not hot) water from the clean side out to flush the dirt out of the filter. It may be necessary to use your fingers on the hose to apply light water pressure. Repeat steps 2 and 3 until the water flowing through the media is completely clear of any dirt and debris.

DRYING – After rinsing, gently shake off excess water and allow it to dry naturally. Re-install the filter onto the intake system, airbox, or custom assembly once it is dry or just slightly damp. Follow all original installation instructions.

  • DO NOT try and speed up the process by using compressed air, oven baking or a blow dryer, this will damage the filter and ruin the material.

REINSTALL – Reinstall your Banks Ram-Air filter element with proper care. Make sure the element seats properly in the filter case. Install the cover making sure it’s in the right position. Tighten all the nuts, bolts, screws, or clips to factory specifications.
