Using the K&N cold air intake kit is easy. First, gather all the necessary tools and follow the included installation guide. It usually takes less than 90 minutes to install. During normal use, enjoy the increased horsepower and torque it provides. When it comes to maintenance, under normal highway driving conditions, you can go up to 100,000 miles before servicing the filter. To clean the filter, use a K&N filter cleaning kit. Just follow the instructions on the kit to wash and re - oil the filter properly. Also, be aware that in California, some intakes are not legal for use on pollution - controlled vehicles. Always check the product specifications for the CARB status of each part for your specific vehicle to avoid any legal issues.
