This guide offers an extensive take a look at why this modification matters, the tools required, and a detailed step-by-step installation procedure.
Why Upgrade the Air Intake System?
A lot of factory air intake systems are developed with sound decrease and cost-efficiency in mind. They often use thick plastic housings and pleated paper filters that focus on peaceful operation over maximum air flow. A cold air intake, alternatively, moves the air filter outside the engine's immediate heat zone or guards it with a heat box, allowing the engine to breathe cooler, denser air.
Secret Benefits of a Cold Air Intake
- Increased Horsepower and Torque: Denser air consists of more oxygen, which results in a more potent combustion cycle. On a Ram 1500, users can generally anticipate gains between 5 to 15 horsepower, depending upon other supporting mods.
- Enhanced Fuel Economy: When the engine breathes easier, it does not need to work as difficult to pull in air. This can lead to a minor increase in MPG, provided the chauffeur preserves consistent driving practices.
- Boosted Engine Sound: The "grumble" of the Ram 1500 becomes far more pronounced under heavy velocity, offering the truck a more muscular existence.
- Reusable Filters: Most aftermarket systems utilize cotton gauze or synthetic filters that can be cleaned up and recycled for the life of the car.

- Disconnect Sensors: Carefully unplug the Air Temperature Sensor (ATS) situated on the side of the factory tube. Make sure not to harm the delicate sensing unit.
- Remove Vent Hoses: Disconnect the crankcase vent hose pipe from the air box.
- Raise Out the Air Box: Most Ram 1500 air boxes are held in by grommets. Securely pull package real estate upward to launch it from the engine bay.
Step 3: Assembling the New Intake
Many CAI packages come in a number of pieces. It is usually much easier to pre-assemble the system on a workbench.
- Attach the Heat Shield: Bolt the weather condition removing and installing brackets onto the new heat shield.
- Install the Filter Adapter: Secure the speed stack or filter adapter to the heat guard housing.
- Transfer the Sensor: Remove the Air Temperature Sensor from the old tube and install it into the new intake tube using the offered grommet.
Step 4: Installing the New System
- Mount the Heat Shield: Place the brand-new heat guard in the location where the factory box sat, using the initial mounting points or provided hardware.
- Connect the Tube: Attach the new intake tube to the throttle body utilizing the offered silicone couplers and pipe clamps. Do not tighten them totally up until television is completely aligned.
- Connect the Filter: Slide the new high-flow filter onto the intake tube or adapter inside the heat shield and tighten up the clamp.
- Reconnect Lines: Reattach the crankcase vent hose pipe and plug in the Air Temperature Sensor.
Step 5: Final Inspection
