LB7 Cold Air Intake: Your Buying Guide
Are you looking to boost your LB7 Duramax diesel truck’s power? A cold air intake (CAI) might be what you need! This guide will help you pick the right one.
Key Features to Look For
You want your CAI to do its job well. Here are some things to watch out for:
- Airflow Capacity: A good CAI lets a lot of air in. Look for one with a high airflow rating. This means more power!

Important Materials
The materials used matter a lot. They affect how well the CAI works and how long it lasts.
- Intake Tube: The tube is usually made of aluminum or plastic. Aluminum is strong and looks good. Plastic can be lighter and cheaper.
- Filter Material: Filters can be made of cotton gauze, synthetic fibers, or foam. Cotton gauze filters are popular.
- Heat Shield Material: Heat shields are often made of steel or plastic. Steel is stronger.
