Upgrade Your Cummins: The Ultimate Cold Air Intake Buying Guide
Are you looking to give your 5.9 Cummins a boost in performance and sound? A cold air intake system might be just the ticket. These upgrades help your engine breathe easier, leading to happier hauling and a more responsive ride. Let’s dive into what makes a good cold air intake for your powerful truck.
Key Features to Look For
When shopping for a cold air intake, keep these important features in mind:
- Airflow Design: The best intakes have a smooth, unobstructed path for air. This means fewer bends and a larger diameter tubing. A well-designed intake allows more air to reach your engine quickly.
- Filtration Quality: The filter is the heart of the system. Look for high-flow, reusable filters made from cotton gauze or synthetic media. These filters trap dirt and debris effectively while letting plenty of air pass through. A clean filter means a happy engine.
- Heat Shielding: Your engine bay gets hot. A good intake system includes a heat shield. This barrier blocks hot engine air from getting into your intake, ensuring your engine gets nice, cool air. Cool air is denser, and denser air means more power.
- Ease of Installation: Some kits are designed for a straightforward bolt-on process. Others might require more tinkering. Check reviews and installation guides to see how difficult the job is.
- Sound Enhancement: Many Cummins owners enjoy the improved intake sound that a cold air intake provides. It often adds a satisfying turbo spooling noise.
Important Materials
The materials used in a cold air intake directly affect its performance and durability.
- Tubing Material: Most intakes use either aluminum or high-quality plastic (like polyethylene). Aluminum is lightweight and durable, but can sometimes conduct heat. Plastic can be a good insulator and is often more affordable.
- Filter Media: As mentioned, cotton gauze and synthetic dry media are top choices for filters. Cotton gauze filters offer excellent filtration and can be cleaned and re-oiled. Synthetic filters are often maintenance-free and provide great airflow.
- Couplers and Clamps: Look for robust silicone couplers and strong, stainless steel clamps. These ensure a secure and airtight seal, preventing leaks.
Factors That Improve or Reduce Quality
Several things can make a cold air intake better or worse.
- Improved Quality:
- Precision Engineering: Intakes designed specifically for the 5.9 Cummins fit better and perform optimally.
- High-Quality Filtration: A filter that effectively cleans the air without restricting flow is crucial.
- Durable Construction: Using strong materials that can withstand the heat and vibrations of engine operation.
- Reduced Quality:
- Cheap Materials: Thin plastic or flimsy metal can break easily.
- Poor Fitment: An intake that doesn’t seal properly will let in hot air or dirt.
- Restrictive Design: Sharp bends or undersized tubing will limit airflow.
User Experience and Use Cases
Most Cummins owners install cold air intakes for a few key reasons:
- Performance Boost: Drivers often report a noticeable increase in throttle response and a bit more horsepower and torque. This is especially helpful for towing or hauling heavy loads.
- Improved Fuel Economy: By allowing the engine to breathe more efficiently, some users see a slight improvement in miles per gallon.
- Enhanced Engine Sound: The satisfying growl and turbo whistle become more pronounced, which many enthusiasts love.
- Easier Maintenance: Reusable filters mean you don’t have to buy replacements as often.
A cold air intake is a great modification for anyone who wants to get more out of their 5.9 Cummins, whether for daily driving, work, or play.
Frequently Asked Questions (FAQ)
Q: Will a cold air intake void my Cummins warranty?
A: Generally, installing a cold air intake is a modification. While it might not automatically void your entire warranty, if a problem arises that can be directly linked to the intake, the manufacturer might deny a warranty claim for that specific issue. It’s always a good idea to check your warranty details.
Q: How much horsepower can I expect from a cold air intake?
A: The horsepower gains from a cold air intake alone are usually modest, often in the range of 5-15 horsepower. It works best when combined with other performance modifications.
Q: Do I need to tune my truck after installing a cold air intake?
A: For most basic cold air intakes on a 5.9 Cummins, a tune is not strictly necessary. The engine’s computer can usually adapt. However, for maximum performance gains, especially when paired with other upgrades, a custom tune is recommended.
Q: How often do I need to clean or replace the air filter?
A: If you have a reusable filter, cleaning frequency depends on your driving conditions. In dusty environments, you might need to clean it every few months. For typical use, once or twice a year is often sufficient. Check the filter visually.
Q: Can I install a cold air intake myself?
A: Yes, most cold air intake kits are designed for DIY installation. They usually come with instructions and all the necessary hardware. If you’re comfortable with basic tools, you can likely do it.
Q: Will a cold air intake affect my emissions?
A: A well-designed cold air intake should not negatively impact your emissions. In fact, by allowing the engine to burn fuel more efficiently, it could potentially have a neutral or even slightly positive effect. However, always ensure the intake you choose is street-legal in your area.
Q: What is the difference between a cold air intake and a short ram intake?
A: A cold air intake places the filter further away from the engine, often in a location where it can draw in cooler outside air. A short ram intake keeps the filter closer to the engine. Cold air intakes generally offer better performance due to cooler air density.
Q: Does a cold air intake make my truck louder?
A: Yes, most cold air intakes will make your truck’s engine sound more aggressive. You’ll often hear more of the turbo spooling sound, especially when accelerating.
Q: Are there any downsides to a cold air intake?
A: The main potential downsides are the cost of the initial purchase and the risk of reduced warranty coverage if an issue arises that can be linked to the modification. Also, in very dusty conditions, you need to be diligent about filter maintenance.
Q: Which brands are reputable for 5.9 Cummins cold air intakes?
A: Some well-regarded brands in the aftermarket for Cummins intakes include AFE Power, S&B Filters, K&N Engineering, and Banks Power. Research specific models for your 5.9 Cummins to find the best fit.
