Necessary Tools and Materials
Among the finest aspects of this installation is that it needs only basic hand tools found in a basic home garage. Before beginning, make sure the vehicle is parked on a level surface with the engine entirely cool to the touch.
Required Equipment:
- Socket Set: Specifically 8mm, 10mm, and 13mm sockets.
- Ratchet and Extensions: A 6-inch extension is often useful for hard-to-reach bolts.
- Screwdrivers: Flathead for loosening up hose clamps and Phillips for housing screws.
- Wrenches: A small adjustable wrench or a 10mm box-end wrench.
- Pliers: To assist with factory vacuum lines or spring clamps.
- Cleaning Rag: To clean down the throttle body entryway.
The Installation Process: Step-by-Step
While particular designs vary between brands-- such as K&N, S&B, or AFE-- the basic workflow for a Dodge Ram 1500 (particularly designs featuring the 5.7 L Hemi) remains consistent.
Step 1: Safety and Preparation
Begin by popping the hood and detaching the unfavorable booster cable. This avoids any electrical shorts and allows the truck's Engine Control Module (ECM) to reset, which helps the computer "discover" the brand-new air flow specifications more rapidly.
Step 2: Removing the Factory System
- Loosen up Clamps: Locate the hose pipe clamps securing the factory intake tube to the throttle body and the air box. Utilize a flathead screwdriver or an 8mm socket to loosen them.
- Detach Sensors: Carefully disconnect the Air Temperature Sensor (ATS) located on the side of the factory tube. Take care not to damage the fragile sensor.
- Eliminate Vent Hoses: Disconnect the crankcase vent pipe from the air box.
- Raise Out the Air Box: Most Ram 1500 air boxes are kept in by grommets. Firmly pull package real estate up to launch it from the engine bay.
Action 3: Assembling the New Intake
Most CAI packages can be found in numerous pieces. It is normally simpler to pre-assemble the system on a workbench.
- Attach the Heat Shield: Bolt the weather condition stripping and mounting 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 brand-new intake tube using the supplied grommet.
Step 4: Installing the New System
- Mount the Heat Shield: Place the new heat guard in the location where the factory box sat, utilizing the initial installing points or provided hardware.
- Link the Tube: Attach the new intake tube to the throttle body utilizing the offered silicone couplers and pipe clamps. Do not tighten them totally till the tube is completely aligned.
- Connect the Filter: Slide the new high-flow filter onto the intake tube or adapter inside the heat guard and tighten the clamp.
- Reconnect Lines: Reattach the crankcase vent pipe and plug in the Air Temperature Sensor.
Step 5: Final Inspection
Check all connections to make sure there are no air leaks. Tighten up all clamps up until they are snug, however prevent over-tightening, which can split plastic parts. Reconnect the unfavorable battery terminal.
Choosing the Right Filter Type
When selecting a package for a Ram 1500, owners need to pick between oiled and dry filters. Both offer efficiency improvements, however they deal with different maintenance choices.
Table 2: Oiled vs. Dry Air Filters
| Filter Type | Pros | Cons |
|---|---|---|
| Oiled (Cotton) | Higher airflow, better for high-performance builds. | Needs oiling after cleansing; can nasty sensors if over-oiled. |
| Dry (Synthetic) | Easier upkeep; no danger of sensor contamination. | Somewhat less air flow than oiled equivalents. |
| Best For | Track usage or optimum HP. | Daily driving and dusty environments. |
Frequently Asked Questions (FAQ)
Does a cold air intake void the lorry warranty?No. Under the
Magnuson-Moss Warranty Act, a manufacturer can not void a lorry's guarantee just due to the fact that an aftermarket part is installed. They should prove that the particular aftermarket part caused a failure to deny a warranty claim.
Is a tune needed after installation?For the large majority of Ram 1500 CAI sets, a tune is not needed. The factory ECM can change the fuel trim within a certain range to accommodate the increased air flow. Nevertheless, a custom tune can assist take full advantage of the gains from the adjustment.
