20 Things You Need To Know About Dodge Ram Cold Air Intake System
Power and Efficiency: The Ultimate Guide to Dodge Ram Cold Air Intake Systems
The Dodge Ram, across its lots of iterations from the 1500 to the durable 2500 and 3500 series, is renowned for its durability and raw power. Whether geared up with Dodge Ram 1500 Accessories or the massive 6.7 L Cummins Diesel, these trucks are built to carry out. Nevertheless, even the most robust factory engineering has constraints determined by mass production and noise guidelines. Among the most effective ways for truck owners to unlock hidden capacity in these automobiles is by replacing the restrictive factory air box with a high-performance Cold Air Intake (CAI) system.
This guide supplies a comprehensive introduction of how cold air intakes function, the benefits they provide for Dodge Ram owners, and what to think about when choosing the ideal system.
How a Cold Air Intake System Functions
To understand the value of a cold air intake, one need to initially understand the physics of internal combustion. Engines require three things to produce power: fuel, trigger, and oxygen. The more oxygen the engine can attract, the more efficiently it burns fuel, leading to increased horsepower and torque.
The Physics of Air Density
Standard factory intakes are typically created to minimize engine sound and suit tight areas. This often results in "hot air intake," where the engine draws in air from the warm engine bay. Warm air is less dense and includes less oxygen particles per cubic inch. Alternatively, 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 automobile, the system presents denser air into the combustion chamber.
Minimizing Restriction
Factory air boxes typically utilize thick paper filters and convoluted "accordion" tubing to moisten noise. These styles develop turbulence and restrict airflow. Aftermarket CAI systems use smooth-walled mandrel-bent tubes and high-flow filters that permit air to reach the throttle body with very little resistance.
The Benefits of Upgrading a Dodge Ram Intake
Installing a cold air intake is frequently the first modification truck enthusiasts carry out since it provides a high return on investment. The following advantages are usually observed after installation:
- Increased Horsepower and Torque: While outcomes vary by engine type and model year, a lot of Dodge Ram owners can anticipate a gain of 5 to 15 horse power.
- Improved Throttle Response: By lowering the effort needed for the engine to breathe, the hold-up in between pressing the gas pedal and the vehicle speeding up is significantly minimized.
- Enhanced Fuel Economy: An engine that breathes more easily operates more effectively. Under steady travelling conditions, many motorists report an increase of 1-- 2 miles per gallon (MPG).
- Aggressive Engine Note: A CAI gets rid of the sound-baffling components of the stock system, permitting the natural growl of the Hemi or Cummins engine to be heard throughout acceleration.
Technical Specifications Comparison
When choosing an intake for a Dodge Ram, owners should choose between various products and setups. The following tables highlight key distinctions.
Table 1: Popular Cold Air Intake Brands for Dodge Ram

| Refined Aluminum | Fair (Can Heat Up) | Very High | Sharper/ Metallic |
| Carbon Fiber | Superior | High/ Premium Cost | Resonance-heavy |
Kinds Of Intake Configurations
There are 2 main styles of cold air consumption available for the Dodge Ram. Each serves a specific purpose depending on how the truck is used.
1. Open Element Systems
These systems feature an exposed filter, normally safeguarded by a metal or plastic shroud referred to as a heat shield.
- Pros: Generally louder and provide the highest volume of airflow. They are often simpler to examine and maintain.
- Cons: They are more prone to "heat soak" if the car is idling in traffic for extended periods.
2. Closed Box Systems
In this setup, the air filter is housed inside a sealed plastic box that links straight to an external air source (such as the wheel well or the front grille).
- Pros: Provides the coolest air temperatures by completely isolating the filter from the engine bay. Suitable for off-roading as they offer much better defense from dust and particles.
- Cons: These systems are typically quieter and can be slightly more challenging to set up due to the exact fitment required.
Setup Process Overview
Among the factors CAI systems are popular is that they are usually "bolt-on" adjustments. This suggests they require no long-term modification to the lorry and can be installed with fundamental hand tools.
Essential Tools:
- Ratchet and socket set (10mm, 13mm are common).
- Flathead and Phillips screwdrivers.
- Torx bits (for specific mass airflow sensors).
- Pliers for factory hose pipe clamps.
General Steps:
- Disconnect the Battery: Always detach the unfavorable terminal to prevent electrical shorts and to permit the ECU to reset its air-fuel trim.
- Eliminate the Factory System: Loosen the clamps at the throttle body and get rid of the bolts holding the stock air box in location.
- Transfer Sensors: Carefully eliminate the Air Temperature Sensor (IAT) or Mass Airflow Sensor (MAF) from the stock tube and install it into the new intake tube.
- Install the Heat Shield/Box: Bolt the brand-new housing into the existing installing points.
- Connect the Tubing: Attach the new intake tube to the throttle body and the air box using the supplied silicone couplers and clamps.
- Protect the Filter: Place the high-flow filter onto the intake tube and tighten.
- Reconnect and Test: Reconnect the battery and begin the engine, inspecting for any air leaks or vibrating elements.
Choosing the Right Filter: Oiled vs. Dry
The heart of the intake system is the filter media. Dodge Ram owners should choose in between oiled and dry choices.
- Oiled Filters: These consist of multiple layers of cotton gauze treated with a special oil. The oil serves as a "tack" to catch tiny dust particles. They are washable and reusable for the life of the automobile however require cautious re-oiling to avoid fouling sensors.
- Dry Filters: These use artificial non-woven products. They are typically much easier to preserve (requiring just a vacuum or a specialized cleaner) and are safer for delicate Mass Airflow Sensors. However, they might need replacement sooner than oiled filters.
Updating a Dodge Ram with a cold air intake system is a practical decision for owners aiming to maximize their truck's ability. By changing limited factory elements with high-flow, heat-shielded designs, chauffeurs can delight in improved acceleration, much better towing performance, and a more resonant engine noise. Whether selecting a sealed S&B system for off-road defense or a high-flow K&N for highway performance, the outcome is a more efficient and powerful driving experience.
Often Asked Questions (FAQ)
1. Will a Cold Air Intake void my Dodge Ram's service warranty?
Under the Magnuson-Moss Warranty Act, a producer can not void a guarantee simply since an aftermarket part was set up. The producer should prove that the aftermarket part specifically caused a failure to reject a claim.
2. Does a Cold Air Intake require a "Tune" or ECU re-mapping?
For many Dodge Ram models, the factory Engine Control Unit (ECU) can adapt to the increased air flow immediately. However, combining an intake with a custom-made tune will yield significantly greater efficiency gains.
3. How frequently should I clean the air filter?
In standard driving conditions, high-performance filters usually need cleaning every 30,000 to 50,000 miles. If the truck is regularly utilized on dirty task sites or off-road tracks, inspections should take place every 10,000 miles.
4. Will a CAI make my truck significantly louder?
It will not increase the volume of the exhaust at idle. Nevertheless, under heavy velocity (Wide Open Throttle), the intake will produce a noticeable "whoosh" noise and a much deeper engine roar.
5. Are Cold Air Intakes legal in all states?
Not necessarily. States that follow California Air Resources Board (CARB) regulations require intake systems to have an Executive Order (EO) number. Owners in those states should make sure the particular design they buy is CARB-compliant.
