20 Fun Facts About Dodge Ram Cold Air Intake System
Power and Efficiency: The Ultimate Guide to Dodge Ram Cold Air Intake Systems
The Dodge Ram, throughout its lots of versions from the 1500 to the sturdy 2500 and 3500 series, is renowned for its durability and raw power. Whether geared up with the legendary 5.7 L Hemi V8 or the huge 6.7 L Cummins Diesel, these trucks are built to carry out. However, even the most robust factory engineering has actually restrictions dictated by mass production and noise guidelines. Among the most reliable methods for truck owners to open hidden capacity in these vehicles is by changing the limiting factory air box with a high-performance Cold Air Intake (CAI) system.
This guide offers a comprehensive summary of how cold air consumption function, the advantages they use for Dodge Ram owners, and what to think about when picking the right system.
How a Cold Air Intake System Functions
To comprehend the worth of a cold air intake, one need to initially comprehend the physics of internal combustion. Engines need 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 consumptions are frequently created to lessen engine noise and fit into tight areas. This often leads to "hot air intake," where the engine attracts air from the warm engine bay. Warm air is less dense and contains fewer oxygen particles per cubic inch. On the other hand, a Cold Air Intake moves the air filter outside the primary engine compartment or shields it from engine heat. By pulling in cooler air from outside the vehicle, the system presents denser air into the combustion chamber.
Decreasing Restriction
Factory air boxes typically use thick paper filters and convoluted "accordion" tubing to moisten sound. These styles produce turbulence and limit airflow. Aftermarket CAI systems use smooth-walled mandrel-bent tubes and high-flow filters that enable air to reach the throttle body with minimal resistance.
The Benefits of Upgrading a Dodge Ram Intake
Setting up a cold air intake is frequently the first modification truck lovers perform due to the fact that it provides a high return on financial investment. The following advantages are normally observed after installation:
- Increased Horsepower and Torque: While outcomes differ by engine type and model year, most Dodge Ram owners can expect a gain of 5 to 15 horse power.
- Enhanced Throttle Response: By decreasing the effort needed for the engine to breathe, the delay in between pushing the gas pedal and the car accelerating is considerably lessened.
- Boosted Fuel Economy: An engine that breathes more quickly runs more efficiently. Under constant 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, permitting the natural growl of the Hemi or Cummins engine to be heard during velocity.
Technical Specifications Comparison
When selecting an intake for a Dodge Ram, owners should choose between different products and configurations. The following tables highlight crucial distinctions.

Kinds Of Intake Configurations
There are two primary designs of cold air consumption readily available for the Dodge Ram. Each serves a specific function depending on how the truck is used.
1. Open Element Systems
These systems include an exposed filter, normally secured by a metal or plastic shroud referred to as a heat guard.
- Pros: Generally louder and supply the greatest volume of air flow. They are frequently much easier to examine and keep.
- Cons: They are more prone to "heat soak" if the automobile 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 temperature levels by entirely separating the filter from the engine bay. Ideal for off-roading as they provide better security from dust and debris.
- Cons: These systems are generally quieter and can be slightly harder to install due to the accurate fitment needed.
Setup Process Overview
Among the reasons CAI systems are popular is that they are usually "bolt-on" adjustments. This implies they need no long-term adjustment to the lorry and can be installed with fundamental hand tools.
Needed Tools:
- Ratchet and socket set (10mm, 13mm prevail).
- 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 allow 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 remove the Air Temperature Sensor (IAT) or Mass Airflow Sensor (MAF) from the stock tube and install it into the brand-new intake tube.
- Install the Heat Shield/Box: Bolt the brand-new real estate into the existing mounting points.
- Link the Tubing: Attach the brand-new intake tube to the throttle body and the air box utilizing the provided silicone couplers and clamps.
- Protect the Filter: Place the high-flow filter onto the intake tube and tighten up.
- Reconnect and Test: Reconnect the battery and start the engine, examining for any air leaks or vibrating elements.
Picking the Right Filter: Oiled vs. Dry
The heart of the intake system is the filter media. Dodge Ram owners should choose between oiled and dry choices.
- Oiled Filters: These include multiple layers of cotton gauze treated with a special oil. The oil serves as a "tack" to capture microscopic dust particles. They are washable and recyclable for the life of the car however need cautious re-oiling to prevent fouling sensors.
- Dry Filters: These make use of synthetic non-woven materials. They are generally simpler to keep (requiring only a vacuum or a specialized cleaner) and are safer for delicate Mass Airflow Sensors. However, they might require replacement faster than oiled filters.
Updating a Dodge Ram with a cold air intake system is a practical decision for owners wanting to optimize their truck's capability. By changing restricted factory parts with high-flow, heat-shielded styles, drivers can delight in improved velocity, much better towing efficiency, and a more resonant engine noise. Whether picking a sealed S&B system for off-road defense or a high-flow K&N for highway efficiency, the result is a more effective and effective 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 producer can not void a guarantee simply due to the fact that an aftermarket part was set up. The producer must prove that the aftermarket part specifically caused a failure to deny 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 immediately. However, combining an intake with a customized tune will yield substantially greater performance gains.
3. How often should click here clean up the air filter?
In basic driving conditions, high-performance filters typically need cleaning every 30,000 to 50,000 miles. If the truck is often utilized on dusty task sites or off-road trails, inspections ought to happen every 10,000 miles.
4. Will a CAI make my truck substantially louder?
It will not increase the volume of the exhaust at idle. However, under read more (Wide Open Throttle), the intake will produce a visible "whoosh" sound 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) policies need intake systems to have an Executive Order (EO) number. Owners in those states must ensure the particular model they purchase is CARB-compliant.
