Using the K&N 69 - 8433TTK Typhoon air intake is simple. First, make sure your vehicle is turned off and cooled down. Use the existing factory mounting points to install the intake. It usually takes about 90 minutes or less. After installation, start your vehicle and enjoy the improved power. As for maintenance, the oversized cone - shaped air filter can last up to 100,000 miles before it needs servicing, but this depends on your driving conditions. If you drive in a very dusty area, you may need to check it more often. Always check the K&N catalog or website to confirm if this air intake is legal for use in your state, as some states have strict emission standards.
