20 Things You Should 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 heavy-duty 2500 and 3500 series, is renowned for its toughness and raw power. Whether equipped with the famous 5.7 L Hemi V8 or the huge 6.7 L Cummins Diesel, these trucks are built to carry out. Nevertheless, even the most robust factory engineering has actually constraints dictated by mass production and sound regulations. Among the most effective methods for truck owners to open hidden capacity in these cars is by replacing the limiting factory air box with a high-performance Cold Air Intake (CAI) system.
This guide provides a detailed introduction of how cold air intakes function, the advantages they provide for Dodge Ram owners, and what to consider when selecting the right system.
How a Cold Air Intake System Functions
To comprehend the worth of a cold air intake, one need to first understand the physics of internal combustion. Engines require 3 things to produce power: fuel, spark, and oxygen. The more oxygen the engine can attract, the more efficiently it burns fuel, leading to increased horse power and torque.
The Physics of Air Density
Requirement factory intakes are typically created to decrease engine sound and fit into tight spaces. This often leads to "hot air intake," where the engine attracts air from the warm engine bay. Warm air is less dense and consists of fewer oxygen particles per cubic inch. On the other hand, a Cold Air Intake moves the air filter outside the primary engine compartment or guards it from engine heat. By drawing in cooler air from outside the lorry, the system introduces denser air into the combustion chamber.
Lowering Restriction
Factory air boxes often utilize thick paper filters and complicated "accordion" tubing to dampen noise. These styles produce 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
Setting up a cold air intake is often the very first modification truck enthusiasts perform because it offers a high return on investment. The following benefits are usually observed after setup:
- Increased Horsepower and Torque: While results vary by engine type and model year, most Dodge Ram owners can expect a gain of 5 to 15 horse power.
- Improved Throttle Response: By decreasing the effort needed for the engine to breathe, the delay between pressing the gas pedal and the vehicle speeding up is substantially minimized.
- Improved Fuel Economy: An engine that breathes more quickly runs more efficiently. Under constant travelling conditions, numerous chauffeurs report a boost of 1-- 2 miles per gallon (MPG).
- Aggressive Engine Note: A CAI eliminates the sound-baffling elements of the stock system, enabling 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 must select between different products and configurations. The following tables highlight essential differences.

Kinds Of Intake Configurations
There are two primary designs of cold air intakes readily available for the Dodge Ram. Each serves a particular purpose depending on how the truck is utilized.
1. Open Element Systems
These systems include an exposed filter, generally secured by a metal or plastic shroud called a heat guard.
- Pros: Generally louder and offer the greatest volume of airflow. They are typically easier to check and preserve.
- Cons: They are more susceptible to "heat soak" if the lorry is idling in traffic for long durations.
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 temperatures by totally isolating the filter from the engine bay. Ideal for off-roading as they provide much better defense from dust and particles.
- Cons: These systems are generally quieter and can be a little more hard to install due to the precise fitment required.
Installation Process Overview
Among the factors CAI systems are popular is that they are normally "bolt-on" adjustments. This indicates they need no long-term adjustment to the lorry and can be installed with basic hand tools.
Necessary Tools:
- Ratchet and socket set (10mm, 13mm prevail).
- Flathead and Phillips screwdrivers.
- Torx bits (for particular mass air flow sensors).
- Pliers for factory hose pipe clamps.
General Steps:
- Disconnect the Battery: Always detach the negative terminal to avoid electrical shorts and to allow the ECU to reset its air-fuel trim.
- Get Rid Of 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 eliminate the Air Temperature Sensor (IAT) or Mass Airflow Sensor (MAF) from the stock tube and install it into the brand-new intake tube.
- Set Up 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 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, checking for any air leaks or vibrating parts.
Choosing the Right Filter: Oiled vs. Dry
The heart of the intake system is the filter media. Dodge Ram owners should decide in between oiled and dry alternatives.
- Oiled Filters: These consist of multiple layers of cotton gauze treated with an unique oil. The oil functions as a "tack" to capture microscopic dust particles. They are washable and recyclable for the life of the car however need mindful re-oiling to avoid fouling sensing units.
- Dry Filters: These use artificial non-woven products. They are normally simpler to keep (requiring just a vacuum or a specialized cleaner) and are much safer for sensitive Mass Airflow Sensors. Nevertheless, they might need replacement quicker than oiled filters.
Updating a Dodge Ram with a cold air intake system is a useful decision for owners seeking to optimize their truck's ability. By changing limited factory elements with high-flow, heat-shielded styles, chauffeurs can enjoy improved acceleration, better towing efficiency, and a more resonant engine sound. Whether choosing a sealed S&B system for off-road security or a high-flow K&N for highway performance, the outcome is a more efficient and powerful driving experience.
Frequently Asked Questions (FAQ)
1. Will a Cold Air Intake void my Dodge Ram's service warranty?
Under the Magnuson-Moss Warranty Act, a manufacturer can not void a service warranty simply due to the fact that an aftermarket part was set up. The maker needs to show that the aftermarket part particularly caused a failure to deny a claim.
2. Does Dodge Ram 1500 Aftermarket Upgrades Intake need a "Tune" or ECU re-mapping?
For a lot of Dodge Ram designs, the factory Engine Control Unit (ECU) can get used to the increased air flow instantly. However, integrating an intake with a customized tune will yield significantly greater performance gains.
3. How often should I clean up the air filter?
In basic driving conditions, high-performance filters generally require cleaning every 30,000 to 50,000 miles. If the truck is regularly used on dusty task websites or off-road routes, examinations must happen every 10,000 miles.
4. Will a CAI make my truck significantly louder?
It will not increase the volume of the exhaust at idle. However, under heavy acceleration (Wide Open Throttle), the intake will produce a visible "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 need to guarantee the particular model they acquire is CARB-compliant.
