The Ultimate Buying Guide: Power Up Your 6.7 Cummins
So, you’re looking to give your 6.7 Cummins a bit more pep in its step? A cold air intake is a great way to do it! It’s like giving your engine a fresh, cool breath of air, which helps it perform better. This guide will help you pick the right one.
What is a Cold Air Intake?
A cold air intake system replaces your truck’s stock air intake. It’s designed to bring cooler, denser air into the engine. Cooler air has more oxygen. More oxygen means your engine can burn fuel more efficiently. This can lead to more horsepower and better fuel economy.
Key Features to Look For
When you’re shopping for a cold air intake, keep these things in mind:
- Improved Airflow: Look for intakes with a larger diameter tubing and a less restrictive air filter. This lets air move more freely.
- Heat Shielding: A good heat shield keeps hot engine bay air away from the intake. This ensures you’re getting the coolest air possible.
- Quality Filter: The air filter is super important. You want one that filters out dirt and debris effectively while still allowing plenty of air through.
- Easy Installation: Most kits are designed for DIY installation. Check for clear instructions and all the necessary hardware.
- Durability: You want a system that will last. Look for sturdy materials and a good warranty.
Important Materials
The materials used in a cold air intake affect its performance and how long it lasts.
- Tubing: Many systems use high-quality plastic or aluminum for the intake tubing. Plastic is often lighter and can help insulate against heat. Aluminum can be very durable.
- Air Filter: Common filter materials include cotton gauze, synthetic dry media, and foam. Cotton gauze filters are known for good airflow and can be cleaned and reused. Synthetic filters also offer good filtration and are often low maintenance.
- Heat Shield: This is usually made from powder-coated steel or aluminum. It needs to be strong and effective at blocking heat.
Factors That Improve or Reduce Quality
Several things can make a cold air intake better or worse.
What Makes a Quality Intake?
- Smooth Tubing: The inside of the intake tube should be smooth. This allows air to flow without getting choppy.
- Proper Sealing: The heat shield and filter should seal tightly against the engine bay. This prevents hot air from sneaking in.
- Reputable Brand: Stick with well-known brands that have good reviews. They usually have better designs and use better parts.
What Can Lower Quality?
- Rough Interior Tubing: Bumps or rough spots inside the tube can slow down airflow.
- Poor Fitment: If the kit doesn’t fit your 6.7 Cummins perfectly, it might not seal well or could be difficult to install.
- Cheap Materials: Using flimsy plastic or low-quality filters won’t give you the best results and might not last.
User Experience and Use Cases
Many Cummins owners install cold air intakes for different reasons.
You’ll often hear people say their truck feels more responsive after installing a cold air intake. Some notice a slight increase in horsepower and torque, especially when towing. Others appreciate the more aggressive intake sound the engine makes under acceleration. It’s a popular upgrade for anyone who wants to get the most out of their diesel engine.
Think about how you use your truck. If you often tow heavy loads, the extra power can be very helpful. If you enjoy spirited driving, you’ll likely feel the difference in acceleration. Even if you just want to improve your truck’s overall efficiency, a cold air intake is a solid choice.
Frequently Asked Questions (FAQ) for 6.7 Cummins Cold Air Intakes
Q: Will a cold air intake void my warranty?
A: Generally, no. Most reputable cold air intakes are designed to be a direct replacement and do not require any permanent modifications. However, it’s always a good idea to check your specific warranty details or consult with your dealer if you have concerns.
Q: How much horsepower can I expect to gain?
A: Gains vary depending on the specific intake, your truck’s condition, and other modifications. Most users see modest gains, typically in the range of 10-25 horsepower. It’s more about improved airflow and throttle response.
Q: Will a cold air intake improve my fuel economy?
A: Many users report a slight improvement in fuel economy. By allowing the engine to breathe easier and burn fuel more efficiently, you might see a small increase in MPG, especially during highway driving.
Q: Does a cold air intake make my truck louder?
A: Yes, it often does. You’ll likely notice a more pronounced intake sound, especially when you accelerate. Some people find this sound desirable.
Q: Can I install a cold air intake myself?
A: Yes, most cold air intake kits are designed for easy DIY installation. They usually come with all the necessary hardware and instructions. If you’re comfortable with basic tools, you can likely install it yourself.
Q: How often do I need to clean or replace the air filter?
A: This depends on the type of filter and the conditions you drive in. Reusable filters (like cotton gauze) can be cleaned and oiled. Dry synthetic filters are often low maintenance. Check the manufacturer’s recommendations for your specific filter.
Q: Will a cold air intake help with towing?
A: Yes, the increased airflow and potential power gains can be beneficial when towing. Your engine will have an easier time breathing, which can help maintain performance under load.
Q: What’s the difference between a dry and oiled air filter?
A: Oiled filters use a special oil to trap dirt. They offer excellent filtration but require cleaning and re-oiling. Dry filters use a synthetic material to trap dirt and are generally low maintenance, often just needing to be tapped clean or replaced.
Q: Are there any potential downsides to a cold air intake?
A: The main potential downside is if the intake isn’t properly sealed, it could draw in hot air, reducing performance. Also, some people dislike the increased intake noise. Always choose a quality product from a reputable brand to minimize risks.
Q: Which brands are good for 6.7 Cummins cold air intakes?
A: Popular and well-regarded brands for 6.7 Cummins cold air intakes include AFE Power, S&B Filters, K&N Engineering, and PPE. Always read reviews for specific models.
