Mounting a cold air intake on your Jeep Cherokee can unlock better performance and efficiency. Many owners notice improved throttle response, a deeper engine sound, and sometimes even a boost in horsepower.
If you’ve never tackled a project like this, don’t worry.
With the right tools, some patience, and careful steps, it’s a straightforward upgrade that can be done at home. Let’s break down how to mount a cold air intake on your Jeep Cherokee, using clear steps and practical advice.
Why Install A Cold Air Intake?
A cold air intake replaces your factory air box and filter with a system designed to pull in cooler air from outside the engine bay. Cooler air is denser and contains more oxygen, which helps your engine burn fuel more efficiently. This can lead to better power, smoother acceleration, and improved fuel economy. For the Jeep Cherokee, especially models with the 4.0L inline-six or 3.2L V6, these benefits are noticeable.
Here’s a quick look at the potential gains:
| Upgrade | Horsepower Increase | Fuel Efficiency Change |
|---|---|---|
| Factory Air Intake | 0 HP | Baseline |
| Cold Air Intake | +5 to +10 HP | +1–2 MPG |
Tools And Parts You’ll Need
Before you start, gather these essentials:
- Cold air intake kit (specific to your Jeep Cherokee model)
- Screwdrivers (flathead and Phillips)
- Socket wrench set
- Pliers
- Clean rag
- Safety gloves
Some kits include all necessary clamps and hoses, but double-check before beginning. Missing parts can delay your project.
Step-by-step Guide To Mounting Cold Air Intake
1. Prepare Your Jeep
Make sure the engine is cool. Disconnect the negative battery terminal to avoid electrical issues. Open your hood and locate the factory air box.
2. Remove The Factory Air Intake
Use your socket wrench to loosen the bolts holding the air box. Remove the air filter, intake tube, and any connected sensors or hoses. Keep sensors like the mass airflow sensor safe—most cold air intake kits require you to reuse them.
| Component | Removal Difficulty | Reuse Required? |
|---|---|---|
| Air Box | Easy | No |
| Intake Tube | Moderate | No |
| Mass Airflow Sensor | Easy | Yes |
3. Install The Cold Air Intake
Follow the kit instructions closely. Usually, you’ll:
- Attach the new intake tube to the throttle body.
- Secure it with supplied clamps.
- Reinstall the mass airflow sensor.
- Connect any hoses to the new intake tube.
- Place the new air filter at the end of the tube.
Check every connection for tightness. Loose fittings can cause performance issues or trigger warning lights.
4. Double-check Everything
Before reconnecting the battery, inspect your work. Make sure no wires are pinched and all hoses are secure.
The air filter should sit away from hot engine parts. If your kit includes a heat shield, install it to keep the filter cool.
5. Start Your Jeep And Test
Reconnect the battery terminal. Start the engine and listen for any unusual sounds. If everything is smooth, take your Jeep for a short drive. You should notice a deeper engine sound and improved throttle response. If a dashboard light appears, double-check the sensor connections.
Practical Tips For Beginners
Many first-time installers miss these points:
- Don’t overtighten clamps. This can crack plastic tubes or damage hoses.
- Check local laws. Some areas restrict aftermarket modifications.
- Keep old parts. If you need to return to stock, having your factory air box can save you money.
- Inspect filter regularly. Clean it every 10,000–15,000 miles for best performance.
An often-overlooked detail: some cold air intakes pull air from near the wheel well. If you drive in heavy rain or off-road, consider a water-resistant filter or splash guard.
Comparing Cold Air Intake Brands
Choosing the right cold air intake is crucial. Here’s how popular brands stack up for Jeep Cherokee:
| Brand | Filter Material | Warranty | Price Range |
|---|---|---|---|
| K&N | Cotton Gauze | Million Mile | $250–$350 |
| Spectre | Non-woven Synthetic | Limited Lifetime | $200–$270 |
| AEM | Dryflow Synthetic | Lifetime | $280–$360 |
Look for a kit that fits your model year exactly. Poor fitment leads to leaks or rattling.
Online forums and reviews can help identify which brands work best for your Jeep Cherokee.
Common Mistakes To Avoid
- Skipping the battery disconnect: Always disconnect the negative terminal before working.
- Ignoring sensor placement: Misplacing the mass airflow sensor can cause engine errors.
- Not using the heat shield: Without it, hot air from the engine bay can reduce performance.
- Failing to check for leaks: After installation, inspect for air leaks which can affect performance.
Frequently Asked Questions
How Long Does It Take To Install A Cold Air Intake?
Most Jeep Cherokee owners complete installation in 45–90 minutes. If you’re new to car DIY projects, take your time and read the instructions carefully.
Will A Cold Air Intake Void My Warranty?
Usually, installing a cold air intake doesn’t void your warranty unless it causes a related problem. Always check your Jeep’s warranty details or talk to your dealer.
Do I Need Special Tools For Installation?
You only need common tools: socket wrench, screwdrivers, and pliers. Some kits may require a special tool for sensor removal, but this is rare.
Can I Drive In The Rain With A Cold Air Intake?
Yes, but if your filter is placed low (near the wheel well), heavy water exposure can be risky. Consider a water-resistant filter or install a splash guard.
What Maintenance Does A Cold Air Intake Need?
Clean the filter every 10,000–15,000 miles. Inspect clamps and hoses during oil changes to ensure everything stays tight.
