How to Install a K&N Cold Air Intake Kit

Installing a K&N air intake in the engine bay

How to Install an Intake System

Installing an intake kit might seem intimidating, especially if it's your first DIY car modification, but thankfully you don't have to be a seasoned mechanic to successfully install a CAI yourself. While every kit is slightly different (since they are designed to be a perfect fit in the engine bay of specific year/make/models), the following is a basic overview of how to install an intake kit in your home garage.

Installation can typically be completed in 60 minutes or less, and requires only simple hand tools. Detailed, step-by-step instructions are included with each kit.

For specific installation instructions for your vehicle, please visit the product page for the intake you want to install and view the installation instruction sheet under the Resources section. For many intake systems, installation videos are available on our YouTube channel.

Do K&N Intakes Increase Horsepower?

K&N intake kits are guaranteed to increase horsepower and torque. Check out the dyno charts on invidivual product pages to see the estimated horsepower increase for your vehicle.

Other intake kit benefits:

K&N is the best in the industry in cold air intake system development, design, and testing. K&N engineers start by employing 3D-laser scanning to create a precise model of each vehicle’s engine bay, and utilize the most advanced technology on the market to create airflow-optimized kits.

In a K&N cold air intake system, air first passes through a performance air filter—typically a High-Flow Air Filter™, which is designed to provide outstanding engine protection—and then passes through an aerodynamically-engineered tubing system that helps prevent unnecessary turbulence/heat.

The included filter only requires cleaning every 100,000 miles under normal highway driving conditions (as opposed to 15,000-20,000 miles for a disposable filter), and provides industry-leading engine protection against contaminants.

SOME INTAKE SYSTEMS ARE NOT LEGAL FOR SALE OR USE ON ANY POLLUTION CONTROL MOTOR VEHICLE IN CALIFORNIA.
