5 Things That Everyone Is Misinformed About On The Subject Of Dodge Ram Cold Air Intake System
Power and Efficiency: The Ultimate Guide to Dodge Ram Cold Air Intake Systems
The Dodge Ram, across its numerous models from the 1500 to the heavy-duty 2500 and 3500 series, is renowned for its durability and raw power. Whether geared up with the famous 5.7 L Hemi V8 or the huge 6.7 L Cummins Diesel, these trucks are constructed to carry out. However, even the most robust factory engineering has actually restrictions determined by mass production and sound guidelines. Among the most effective ways for truck owners to unlock hidden capacity in these cars is by replacing the limiting factory air box with a high-performance Cold Air Intake (CAI) system.
This guide supplies a thorough introduction of how cold air intakes function, the benefits they use for Dodge Ram owners, and what to consider when choosing the right system.
How a Cold Air Intake System Functions
To comprehend the worth of a cold air intake, one need to 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 efficiently it burns fuel, leading to increased horsepower and torque.
The Physics of Air Density
Standard factory consumptions are often created to decrease engine sound and suit tight spaces. This frequently results in "hot air intake," where the engine draws in air from the warm engine bay. Warm air is less thick and contains less oxygen molecules per cubic inch. On the other hand, a Cold Air Intake moves the air filter outside the main engine compartment or guards it from engine heat. By pulling in cooler air from outside the vehicle, the system introduces denser air into the combustion chamber.
Minimizing Restriction
Factory air boxes frequently utilize thick paper filters and complicated "accordion" tubing to dampen sound. These designs develop turbulence and restrict air flow. Aftermarket CAI systems make use of 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 very first modification truck enthusiasts perform since it uses a high roi. The following advantages are usually observed after setup:
- Increased Horsepower and Torque: While outcomes differ by engine type and model year, the majority of Dodge Ram owners can expect a gain of 5 to 15 horsepower.
- Improved Throttle Response: By decreasing the effort needed for the engine to breathe, the delay between pressing the gas pedal and the car speeding up is significantly lessened.
- Boosted Fuel Economy: An engine that breathes more quickly operates more efficiently. Under stable travelling conditions, numerous motorists report an increase of 1-- 2 miles per gallon (MPG).
- Aggressive Engine Note: A CAI gets rid of the sound-baffling parts of the stock system, allowing the natural growl of the Hemi or Cummins engine to be heard throughout velocity.
Technical Specifications Comparison
When selecting an intake for a Dodge Ram, owners must select between different products and configurations. The following tables highlight key differences.

Kinds Of Intake Configurations
There are 2 primary designs of cold air intakes readily available for the Dodge Ram. Each serves a particular function depending on how the truck is utilized.
1. Open Element Systems
These systems feature an exposed filter, generally secured by a metal or plastic shroud referred to as a heat guard.
- Pros: Generally louder and offer the greatest volume of airflow. They are frequently easier to examine and keep.
- Cons: They are more prone to "heat soak" if the lorry is idling in traffic for long periods.
2. Closed Box Systems
In this configuration, 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 temperature levels by entirely isolating the filter from the engine bay. Suitable for off-roading as they offer better protection from dust and particles.
- Cons: These systems are usually quieter and can be somewhat harder to set up due to the precise fitment required.
Installation Process Overview
Among the factors CAI systems are popular is that they are typically "bolt-on" adjustments. This suggests they require no long-term modification to the automobile and can be set up with basic hand tools.
Essential Tools:
- Ratchet and socket set (10mm, 13mm prevail).
- Flathead and Phillips screwdrivers.
- Torx bits (for particular mass airflow sensing units).
- Pliers for factory hose 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 remove 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 new housing into the existing installing points.
- Link the Tubing: Attach the new intake tube to the throttle body and the air box using the offered 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 leakages or vibrating parts.
Selecting the Right Filter: Oiled vs. Dry
The heart of the intake system is the filter media. Dodge Ram owners must choose 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 tiny dust particles. They are washable and recyclable for the life of the lorry but require cautious re-oiling to prevent fouling sensing units.
- Dry Filters: These utilize artificial non-woven materials. They are generally easier to keep (needing just a vacuum or a specialized cleaner) and are safer for sensitive Mass Airflow Sensors. Nevertheless, they might require replacement faster than oiled filters.
Upgrading a Dodge Ram with a cold air intake system is a useful decision for owners seeking to maximize their truck's ability. By replacing limited Dodge Ram 1500 Air Intake Upgrade with high-flow, heat-shielded styles, motorists can enjoy enhanced acceleration, much better towing efficiency, and a more resonant engine noise. Whether choosing a sealed S&B system for off-road defense or a high-flow K&N for highway efficiency, the outcome is a more efficient and effective driving experience.
Often 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 just due to the fact that an aftermarket part was set up. The producer needs to prove that the aftermarket part particularly caused a failure to reject a claim.
2. Does a Cold Air Intake require a "Tune" or ECU re-mapping?
For many Dodge Ram designs, the factory Engine Control Unit (ECU) can adapt to the increased airflow instantly. Nevertheless, integrating an intake with a customized tune will yield significantly higher performance gains.
3. How typically should I clean the air filter?
In basic driving conditions, high-performance filters generally require cleaning every 30,000 to 50,000 miles. If the truck is frequently used on dirty job websites or off-road routes, evaluations must take place every 10,000 miles.
4. Dodge Ram Truck Accessories make my truck substantially 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" noise and a much deeper engine growl.
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 must guarantee the particular model they acquire is CARB-compliant.
