FAQs
Q: Will a cold air intake void my warranty?
A: Installing a CAI *could* potentially void parts of your warranty if it’s proven that the CAI directly caused a failure. However, many CAIs are CARB-certified and designed to be compliant with emissions regulations, which can help avoid warranty issues. Always check with your dealer to be sure.
Q: How much horsepower will a cold air intake add?
A: Horsepower gains vary depending on the CAI and your vehicle’s specific setup. Generally, you can expect to see gains of around 10-15 horsepower with a quality CAI.
Q: Do I need to tune my engine after installing a cold air intake?
A: Some CAIs are designed to work with the factory tune, while others may require a custom tune to optimize performance. Check the manufacturer’s recommendations and consider a tune if you want to maximize the benefits of your CAI.
Q: How often should I clean my cold air intake filter?
A: The frequency of cleaning depends on driving conditions. Generally, you should clean your CAI filter every 25,000 to 50,000 miles, or more frequently if you drive in dusty environments.
