Your Guide to Cold Air Intakes for the 5.9 Cummins
So, you own a 5.9 Cummins and want to give it a little more pep. A cold air intake might be just the ticket! Think of it like giving your engine a big, deep breath of cool, fresh air. This guide will help you pick the best one.
What is a Cold Air Intake?
A cold air intake replaces your truck’s stock air intake system. It uses a bigger, often cone-shaped air filter and smoother piping. The goal is to let your engine breathe easier and suck in cooler air. Cooler air is denser, meaning it has more oxygen. More oxygen helps your engine burn fuel better, which can lead to more power and better fuel economy.
Key Features to Look For
When you shop for a cold air intake for your 5.9 Cummins, keep these things in mind:
- Filter Type: Look for high-flow air filters. These let air pass through easily. Some are washable and reusable, which saves money in the long run. Others are disposable.
- Material Quality: The piping should be made of strong stuff. Think polished aluminum or durable plastic. This helps prevent cracks and keeps the air cool.
- Sealed Design: A good intake will have a heat shield or a sealed box. This stops hot air from under the hood from getting into your engine. Cooler air is key!
- Ease of Installation: Some kits are bolt-on and don’t need many special tools. Others might be trickier. Check reviews for installation tips.
- Sound: Cold air intakes can make your Cummins sound a bit more aggressive. Some people love this rumble, while others prefer a quieter ride.
Important Materials
The materials used in a cold air intake matter a lot.
- Aluminum: Polished aluminum piping looks sharp. It’s also good at keeping the air cool. However, it can get hot if not shielded well.
- Plastic: High-quality plastics, like polyethylene, are also used. They are often lighter and don’t transfer heat as much as aluminum.
- Rubber or Silicone Couplers: These connect the different parts of the intake. Good quality rubber or silicone will last longer and seal better.
- Air Filter Media: Filters are usually made of cotton gauze or synthetic materials. Cotton gauze filters are often washable and offer great airflow. Synthetic filters can offer excellent filtration.
Factors That Improve or Reduce Quality
- Improves Quality:
- A well-designed heat shield or sealed airbox is a big plus. It keeps hot engine bay air out.
- Smooth, mandrel-bent piping helps air flow without getting choppy.
- A high-quality, reusable air filter can save you money and perform well for years.
- Reduces Quality:
- Cheap plastic or thin metal can crack or warp.
- Poorly designed intakes might not seal well, letting hot air in.
- A filter that clogs easily will hurt performance.
User Experience and Use Cases
Most owners who install a cold air intake on their 5.9 Cummins report positive changes.
- Daily Driving: You might notice a bit more responsiveness when you hit the gas. Some drivers also see a slight improvement in fuel mileage.
- Towing: If you tow heavy loads, a cold air intake can help your engine run cooler and more efficiently. This is especially true when climbing hills.
- Performance: While not a massive power upgrade on its own, it’s a great first step for anyone planning further engine modifications. It helps your engine breathe better for future upgrades.
- Sound: Many drivers enjoy the deeper, more throaty sound the Cummins makes with a new intake.
