Upgrade Your Ram 3500 Diesel: The Ultimate Cold Air Intake Buying Guide
A cold air intake is a great way to give your Ram 3500 diesel truck a little more pep. It helps your engine breathe better, which can lead to a few nice improvements. Let’s dive into what you need to know before you buy one.
Key Features to Look For
When you’re shopping for a cold air intake, keep these important features in mind:
Improved Airflow
This is the main point of a cold air intake. You want a system that lets more air into your engine. Look for a larger diameter intake tube and a big, open air filter. This means your engine can get the air it needs more easily.
Heat Shielding
Your engine bay gets hot. A good cold air intake will have a heat shield. This is a box or barrier that keeps hot air from the engine away from the cold air filter. Less hot air means cooler, denser air for your engine. Denser air has more oxygen, which helps with power.
Filter Type
There are a few common filter types.
- Cotton Gauze: These are reusable and offer good filtration. You clean them with a special kit.
- Dry/Synthetic: These are also often reusable and might offer slightly better airflow. They are usually cleaned with compressed air or mild soap.
Choose a filter that fits your maintenance style.
Ease of Installation
Some kits are designed for a simple bolt-on installation. Others might require more tools or time. Check reviews to see how easy it is to put on.
Important Materials
The materials used in a cold air intake affect its durability and performance.
Intake Tubing
Most good intakes use materials like polished aluminum or durable, high-density plastic (like polyethylene). These materials don’t get too hot and are strong.
Air Filter Material
As mentioned, cotton gauze and synthetic materials are common for the filter itself. Both work well.
Heat Shield Material
Heat shields are often made from powder-coated steel or aluminum. These materials are good at blocking heat.
Factors That Improve or Reduce Quality
Several things can make a cold air intake better or worse.
Design and Engineering
A well-designed intake system is carefully engineered to fit your Ram 3500 diesel perfectly. It should guide air smoothly and efficiently. Poorly designed systems might cause turbulence, which hurts performance.
Filtration Efficiency
While you want more air, you also need clean air. A high-quality filter will trap dirt and debris effectively without restricting airflow too much.
Durability and Fitment
A quality intake will be built to last. It should have strong connections and seals. A poor fit can lead to air leaks, which defeats the purpose.
User Experience and Use Cases
Most Ram 3500 diesel owners install cold air intakes for a few reasons.
Performance Boost
Many users report a noticeable increase in throttle response. The truck might feel a little quicker off the line. Some also experience a slight improvement in fuel economy, though this can vary.
Engine Sound
You might hear a more aggressive, deeper intake sound when you accelerate. Some people love this sound.
Towing and Hauling
For trucks that tow or haul heavy loads, the extra airflow can help the engine perform better under strain. It can help keep engine temperatures more stable.
Frequently Asked Questions (FAQ)
Q: Will a cold air intake void my Ram 3500 diesel’s warranty?
A: Usually, a cold air intake won’t void your warranty unless it causes a problem that the manufacturer can prove is directly related to the intake. It’s always a good idea to check your warranty details or talk to your dealer.
Q: How much horsepower can I expect from a cold air intake?
A: You won’t see massive horsepower gains from just a cold air intake on its own. Typically, you might gain 5-15 horsepower. It’s more about improving efficiency and throttle response.
Q: Is a cold air intake hard to install on a Ram 3500 diesel?
A: For most DIYers, a cold air intake is a moderate installation. It usually involves removing the stock airbox and bolting in the new system. Some kits come with detailed instructions.
Q: Do I need a tune for a cold air intake?
A: For most basic cold air intakes, a tune is not strictly necessary. However, to get the most out of your intake and other modifications, a custom tune can help optimize your engine’s performance.
Q: How often do I need to clean or replace the air filter?
A: This depends on the filter type and how dusty your driving conditions are. Reusable filters usually need cleaning every 15,000-30,000 miles. Check the manufacturer’s recommendations.
Q: Will a cold air intake make my exhaust louder?
A: A cold air intake primarily affects the intake sound. It won’t directly make your exhaust louder, but you might notice a more pronounced engine sound under acceleration.
Q: Can I install a cold air intake in the rain?
A: It’s best to avoid installing any engine components in heavy rain. While the filter is designed to handle some moisture, installing it in wet conditions could be difficult and risky.
Q: Are there specific cold air intakes better for towing?
A: Any well-designed cold air intake will help with towing by providing more airflow. Look for systems with good heat shielding to keep intake air cooler, which is beneficial under load.
Q: What’s the difference between a cold air intake and a short ram intake?
A: A cold air intake moves the filter further away from the engine to draw in cooler air. A short ram intake keeps the filter closer to the engine, making installation easier but potentially drawing in warmer air.
Q: Where is the best place to buy a cold air intake for my Ram 3500 diesel?
A: You can find cold air intakes from online automotive retailers, truck accessory stores, and directly from the manufacturers. Reading customer reviews can help you choose a reputable seller.
