The Diagnostic / The Situation
When it comes to upgrading your Jeep’s performance, one of the most popular modifications is installing a new intake system. Two of the most common types of intake systems are cold air intakes and short ram intakes. While both types of intakes can improve your Jeep’s performance, they have distinct differences in terms of design, functionality, and benefits. In this guide, we will delve into the technical aspects of cold air intakes and short ram intakes, and explore the advantages and disadvantages of each.

Symptoms or signs to look for when considering an intake upgrade include decreased engine performance, reduced horsepower, and lower fuel efficiency. If you notice any of these symptoms, it may be time to consider upgrading your Jeep’s intake system.
Technical Deep Dive
A cold air intake is designed to draw in cooler air from outside the engine compartment, typically from the fender or behind the bumper. This cooler air is denser and contains more oxygen, which can lead to increased horsepower and torque. Cold air intakes usually feature a longer tube or pipe that extends from the air filter to the engine, allowing the air to travel a longer distance and become cooler.
On the other hand, a short ram intake is designed to draw in air from within the engine compartment. This type of intake features a shorter tube or pipe that connects the air filter to the engine, resulting in a shorter distance for the air to travel. Short ram intakes are often less expensive and easier to install than cold air intakes.
Common failure points to consider when installing an intake system include the air filter, mass airflow sensor, and throttle body. It is essential to ensure that these components are functioning properly and are compatible with the new intake system.

Step-by-Step Guide
Step 1: Prepare the Vehicle
Remove the Negative Battery Cable
Disconnect the negative battery cable to prevent any accidental engine starts.
Locate the Intake System
Identify the location of the intake system, including the air filter, mass airflow sensor, and throttle body.
Step 2: Remove the Old Intake System
Remove the Air Filter
Use an air filter wrench to remove the old air filter.
Disconnect the Mass Airflow Sensor
Carefully disconnect the mass airflow sensor from the old intake system.
Remove the Throttle Body
Use a 10mm socket to remove the throttle body from the old intake system.
Step 3: Install the New Intake System
Install the New Air Filter
Place the new air filter onto the new intake system, ensuring it is securely fastened.
Connect the Mass Airflow Sensor
Reconnect the mass airflow sensor to the new intake system.
Install the Throttle Body
Use a 10mm socket to install the throttle body onto the new intake system.
Step 4: Connect the New Intake System
Connect the Intake Tube
Connect the new intake tube to the throttle body, ensuring it is securely fastened with hose clamps.
Connect the Air Filter
Connect the new air filter to the intake tube, ensuring it is securely fastened.
Step 5: Test the New Intake System
Start the Engine
Start the engine and listen for any unusual noises or vibrations.
Check for Leaks
Use a vacuum gauge to check for any leaks in the intake system.
Pro Tips & Common Mistakes
- Always follow the manufacturer’s instructions when installing a new intake system.
- Ensure the new intake system is compatible with your Jeep’s engine and transmission.
- Avoid over-tightening the intake tube or throttle body, as this can cause damage to the engine.
Cost Analysis: DIY vs Mechanic
The cost of a new intake system can range from $200 to $500, depending on the type and quality of the system. If you choose to install the system yourself, you can save on labor costs, which can range from $100 to $300. However, if you are not experienced with DIY repairs, it is recommended to have a professional mechanic install the system to ensure it is done correctly.
Frequently Asked Questions
- Q: What is the difference between a cold air intake and a short ram intake? A: A cold air intake draws in cooler air from outside the engine compartment, while a short ram intake draws in air from within the engine compartment.
- Q: How do I know which type of intake system is right for my Jeep? A: Consider your driving habits, climate, and engine type when choosing an intake system. Cold air intakes are suitable for most driving conditions, while short ram intakes are better suited for high-performance driving.
- Q: Can I install a new intake system myself? A: Yes, if you have experience with DIY repairs and are comfortable with the installation process. However, if you are not experienced, it is recommended to have a professional mechanic install the system.
- Q: Will a new intake system improve my Jeep’s fuel efficiency? A: Yes, a new intake system can improve your Jeep’s fuel efficiency by allowing the engine to breathe more efficiently.
- Q: Do I need to tune my Jeep’s engine after installing a new intake system? A: Yes, it is recommended to have your Jeep’s engine tuned after installing a new intake system to ensure optimal performance and fuel efficiency.
