Using this K&N intake kit is straightforward. First, make sure your engine is cool before installation. You can typically finish the installation in less than an hour. After installation, your Acura Integra will enjoy improved airflow and performance. Under normal highway driving, you can go up to 100,000 miles before servicing the air filter. To clean the filter, simply wash it with a mild detergent and let it dry completely. Then, re - oil it with the appropriate K&N filter oil. Remember, in California, some intakes aren't legal for pollution - controlled vehicles, so always check the CARB status for your specific vehicle and part before use.
