15 Things To Give That Dodge Ram Cold Air Intake System Lover In Your Life
Power and Efficiency: The Ultimate Guide to Dodge Ram Cold Air Intake Systems
The Dodge Ram, across its lots of versions from the 1500 to the sturdy 2500 and 3500 series, is renowned for its toughness and raw power. Whether equipped with the legendary 5.7 L Hemi V8 or the enormous 6.7 L Cummins Diesel, these trucks are constructed to carry out. Nevertheless, even the most robust factory engineering has actually restrictions determined by mass production and noise regulations. Among the most efficient methods for truck owners to open concealed potential in these cars is by changing the limiting factory air box with a high-performance Cold Air Intake (CAI) system.
This guide provides a thorough introduction of how cold air intakes function, the benefits they provide for Dodge Ram owners, and what to think about when choosing the best system.
How a Cold Air Intake System Functions
To understand the value of a cold air intake, one must initially understand the physics of internal combustion. Engines need three things to produce power: fuel, spark, and oxygen. The more oxygen the engine can attract, the more effectively it burns fuel, leading to increased horsepower and torque.
The Physics of Air Density
Requirement factory consumptions are typically designed to reduce engine noise and suit tight spaces. This typically leads to "hot air intake," where the engine draws in air from the warm engine bay. Warm air is less thick and includes less oxygen molecules per cubic inch. Conversely, a Cold Air Intake moves the air filter outside the primary engine compartment or guards it from engine heat. By pulling in cooler air from outside the lorry, the system introduces denser air into the combustion chamber.
Reducing Restriction
Factory air boxes typically utilize thick paper filters and complicated "accordion" tubing to moisten sound. These styles develop turbulence and limit air flow. Aftermarket CAI systems use smooth-walled mandrel-bent tubes and high-flow filters that allow air to reach the throttle body with very little resistance.
The Benefits of Upgrading a Dodge Ram Intake
Installing a cold air intake is typically the first modification truck enthusiasts carry out because it provides a high return on investment. The following benefits are generally observed after installation:
- Increased Horsepower and Torque: While results vary by engine type and model year, the majority of Dodge Ram owners can expect a gain of 5 to 15 horse power.
- Enhanced Throttle Response: By minimizing the effort needed for the engine to breathe, the hold-up between pressing the gas pedal and the lorry speeding up is substantially decreased.
- Improved Fuel Economy: An engine that breathes more quickly operates more effectively. Under stable travelling conditions, lots of motorists report an increase of 1-- 2 miles per gallon (MPG).
- Aggressive Engine Note: A CAI eliminates the sound-baffling parts of the stock system, enabling the natural roar of the Hemi or Cummins engine to be heard during acceleration.
Technical Specifications Comparison
When choosing an intake for a Dodge Ram, owners must pick in between different materials and setups. The following tables highlight essential distinctions.
Table 1: Popular Cold Air Intake Brands for Dodge Ram
| Brand name | Real estate Type | Filter Type | Best Known For |

| Carbon Fiber | Superior | High/ Premium Cost | Resonance-heavy |
Kinds Of Intake Configurations
There are 2 primary designs of cold air consumption offered for the Dodge Ram. Each serves a particular function depending upon how the truck is utilized.
1. Open Element Systems
These systems feature an exposed filter, typically secured by a metal or plastic shroud called a heat shield.
- Pros: Generally louder and supply the highest volume of air flow. They are often easier to examine and keep.
- Cons: They are more prone to "heat soak" if the car is idling in traffic for extended periods.
2. Closed Box Systems
In this configuration, the air filter is housed inside a sealed plastic box that connects directly to an external air source (such as the wheel well or the front grille).
- Pros: Provides the coolest air temperature levels by totally separating the filter from the engine bay. Suitable for off-roading as they offer much better protection from dust and debris.
- Cons: These systems are usually quieter and can be a little harder to install due to the precise fitment needed.
Setup Process Overview
Among the reasons CAI systems are popular is that they are usually "bolt-on" modifications. This indicates they need no irreversible modification to the automobile and can be set up with standard hand tools.
Needed Tools:
- Ratchet and socket set (10mm, 13mm prevail).
- Flathead and Phillips screwdrivers.
- Torx bits (for certain mass airflow sensing units).
- Pliers for factory hose pipe clamps.
General Steps:
- Disconnect the Battery: Always disconnect the unfavorable terminal to avoid electrical shorts and to enable the ECU to reset its air-fuel trim.
- Remove the Factory System: Loosen the clamps at the throttle body and eliminate the bolts holding the stock air box in location.
- Transfer Sensors: Carefully get rid of the Air Temperature Sensor (IAT) or Mass Airflow Sensor (MAF) from the stock tube and install it into the new intake tube.
- Set Up the Heat Shield/Box: Bolt the brand-new real estate into the existing installing points.
- Connect the Tubing: Attach the new intake tube to the throttle body and the air box utilizing the provided silicone couplers and clamps.
- Secure the Filter: Place the high-flow filter onto the intake tube and tighten.
- Reconnect and Test: Reconnect the battery and begin the engine, looking for any air leaks or vibrating parts.
Selecting the Right Filter: Oiled vs. Dry
The heart of the intake system is the filter media. Dodge Ram owners need to decide between oiled and dry options.
- Oiled Filters: These consist of numerous layers of cotton gauze treated with an unique oil. The oil functions as a "tack" to capture microscopic dust particles. They are washable and multiple-use for the life of the vehicle but need cautious re-oiling to prevent fouling sensing units.
- Dry Filters: These make use of artificial non-woven products. They are typically simpler to maintain (needing just a vacuum or a specialized cleaner) and are much safer for delicate Mass Airflow Sensors. Nevertheless, they might require replacement earlier than oiled filters.
Upgrading a Dodge Ram with a cold air intake system is a useful decision for owners wanting to maximize their truck's capability. By replacing restricted factory parts with high-flow, heat-shielded styles, chauffeurs can delight in improved velocity, much better towing performance, and a more resonant engine noise. Whether choosing a sealed S&B system for off-road protection or a high-flow K&N for highway efficiency, the outcome is a more efficient and effective driving experience.
Regularly Asked Questions (FAQ)
1. Will a Cold Air Intake void my Dodge Ram's warranty?
Under the Magnuson-Moss Warranty Act, a producer can not void a warranty merely since an aftermarket part was set up. The maker must show that the aftermarket part specifically caused a failure to reject a claim.
2. Does a Cold Air Intake need a "Tune" or ECU re-mapping?
For many Dodge Ram designs, the factory Engine Control Unit (ECU) can adapt to the increased air flow automatically. However, combining an intake with a customized tune will yield significantly higher efficiency gains.
3. How often should I clean up the air filter?
In basic driving conditions, high-performance filters normally require cleansing every 30,000 to 50,000 miles. If the truck is often utilized on dusty task website s or off-road routes, inspections ought to occur every 10,000 miles.
4. Will a CAI make my truck considerably louder?
It will not increase the volume of the exhaust at idle. However, under heavy acceleration (Wide Open Throttle), the intake will produce a noticeable "whoosh" sound and a deeper engine grumble.
5. Are Cold Air Intakes legal in all states?
Not always. States that follow California Air Resources Board (CARB) policies need intake systems to have an Executive Order (EO) number. Owners in those states must ensure the specific model they buy is CARB-compliant.
