14 Common Misconceptions Concerning Dodge Ram Cold Air Intake System
Power and Efficiency: The Ultimate Guide to Dodge Ram Cold Air Intake Systems
The Dodge Ram, throughout its numerous iterations from the 1500 to the sturdy 2500 and 3500 series, is renowned for its durability and raw power. Whether equipped with the legendary 5.7 L Hemi V8 or the massive 6.7 L Cummins Diesel, these trucks are developed to perform. Nevertheless, even the most robust factory engineering has actually constraints determined by mass production and sound regulations. One of the most reliable methods for truck owners to unlock surprise 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 detailed summary of how cold air consumption function, the advantages they provide for Dodge Ram owners, and what to think about when choosing the right system.
How a Cold Air Intake System Functions
To comprehend the value of a cold air intake, one need to initially comprehend the physics of internal combustion. Engines require 3 things to produce power: fuel, spark, and oxygen. The more oxygen the engine can draw in, the more efficiently it burns fuel, leading to increased horsepower and torque.
The Physics of Air Density
Requirement factory consumptions are often developed to lessen engine sound and fit into tight spaces. This typically leads to "hot air intake," where the engine draws in air from the warm engine bay. Warm air is less dense and includes fewer oxygen molecules per cubic inch. On the other hand, a Cold Air Intake moves the air filter outside the main engine compartment or shields it from engine heat. By pulling in cooler air from outside the car, the system presents denser air into the combustion chamber.
Decreasing Restriction
Factory air boxes frequently use thick paper filters and convoluted "accordion" tubing to dampen noise. These styles produce turbulence and limit airflow. Dodge Ram 1500 Performance Accessories 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 often the first modification truck enthusiasts perform because it offers a high return on financial investment. The following advantages are typically observed after installation:
- Increased Horsepower and Torque: While outcomes differ by engine type and model year, the majority of Dodge Ram owners can anticipate a gain of 5 to 15 horsepower.
- Improved Throttle Response: By minimizing the effort needed for the engine to breathe, the hold-up in between pressing the gas pedal and the vehicle accelerating is substantially minimized.
- Enhanced Fuel Economy: An engine that breathes more quickly runs more effectively. Under steady cruising conditions, lots of 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, allowing the natural grumble of the Hemi or Cummins engine to be heard during acceleration.
Technical Specifications Comparison
When picking an intake for a Dodge Ram, owners must select between different materials and setups. The following tables highlight crucial differences.

Types of Intake Configurations
There are two primary designs of cold air intakes available for the Dodge Ram. Each serves a specific purpose depending upon how the truck is utilized.
1. Open Element Systems
These systems feature an exposed filter, usually safeguarded by a metal or plastic shroud understood as a heat shield.
- Pros: Generally louder and supply the greatest volume of air flow. They are frequently simpler to examine and keep.
- Cons: They are more susceptible 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 links directly to an external air source (such as the wheel well or the front grille).
- Pros: Provides the coolest air temperatures by totally isolating the filter from the engine bay. Perfect for off-roading as they provide better defense from dust and particles.
- Cons: These systems are normally quieter and can be somewhat more challenging to set up due to the accurate fitment required.
Installation Process Overview
One of the factors CAI systems are popular is that they are typically "bolt-on" modifications. This indicates they require no long-term modification to the car and can be set up with fundamental hand tools.
Required Tools:
- Ratchet and socket set (10mm, 13mm are common).
- Flathead and Phillips screwdrivers.
- Torx bits (for certain mass airflow sensing units).
- Pliers for factory pipe clamps.
General Steps:
- Disconnect the Battery: Always disconnect the unfavorable terminal to prevent 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 get rid of the bolts holding the stock air box in place.
- 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 new housing into the existing mounting points.
- Connect the Tubing: Attach the brand-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 up.
- Reconnect and Test: Reconnect the battery and start the engine, inspecting for any air leakages or vibrating elements.
Picking the Right Filter: Oiled vs. Dry
The heart of the intake system is the filter media. Dodge Ram owners need to choose between oiled and dry options.
- Oiled Filters: These consist of numerous layers of cotton gauze treated with a special oil. The oil acts as a "tack" to capture microscopic dust particles. They are washable and reusable for the life of the automobile but require careful re-oiling to avoid fouling sensing units.
- Dry Filters: These make use of synthetic non-woven materials. They are usually much easier to keep (requiring only a vacuum or a specialized cleaner) and are much safer for sensitive Mass Airflow Sensors. Nevertheless, they may need replacement quicker than oiled filters.
Updating a Dodge Ram with a cold air intake system is a practical choice for owners looking to optimize their truck's ability. By changing restricted factory components with high-flow, heat-shielded styles, chauffeurs can take pleasure in enhanced acceleration, much better towing performance, and a more resonant engine noise. Whether picking a sealed S&B system for off-road security or a high-flow K&N for highway efficiency, the result is a more efficient and powerful 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 service warranty just due to the fact that an aftermarket part was installed. The maker needs to show that the aftermarket part specifically triggered a failure to deny a claim.
2. Does a Cold Air Intake need a "Tune" or ECU re-mapping?
For most Dodge Ram designs, the factory Engine Control Unit (ECU) can adapt to the increased air flow automatically. Nevertheless, combining an intake with a customized tune will yield significantly higher efficiency gains.
3. How often should I clean the air filter?
In basic driving conditions, high-performance filters usually require cleaning every 30,000 to 50,000 miles. If the truck is frequently utilized on dusty task sites or off-road trails, examinations 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 an obvious "whoosh" sound and a deeper engine roar.
5. Are Cold Air Intakes legal in all states?
Not always. States that follow California Air Resources Board (CARB) policies require intake systems to have an Executive Order (EO) number. Owners in those states ought to make sure the specific design they buy is CARB-compliant.
