The installation of a K&N cold air intake system involves several steps, beginning with disconnecting the vehicle’s battery and proceeding through the removal of the factory intake system components. The process includes transferring the mass air sensor to a K&N adapter, securing the new air filter housing, and connecting necessary ventilation lines. K&N states that these intake kits are designed to increase horsepower and torque, and are developed using advanced technologies like 3D laser scanning to optimize airflow. The company also provides customer support for installation questions.
Preparation and Disconnection
Prior to beginning the installation process, it is necessary to turn off the ignition and disconnect the negative battery cable. This precautionary step is outlined as the initial action in the installation procedure. Following this, the mass air flow sensor electrical connection must be disconnected. Additionally, the EVAP vent line and/or crankcase vent line should be disconnected from the intake plenum and valve cover vent port. These disconnections prepare the vehicle for the removal of the existing factory intake system.
Removal of the Factory Intake System
The removal of the original intake system requires loosening hose clamps that secure the intake tube to both the throttle body and the air filter housing. Once loosened, the stock intake tube can be removed. Further disassembly involves releasing the clips that secure the upper air filter housing, allowing for its removal. Finally, the bolt securing the air filter housing to the inner fender or core support must be removed to fully liberate the factory air filter housing.
Component Transfer and Installation
With the factory intake system removed, the process shifts to preparing and installing the K&N components. This begins with installing provided edge trim onto the K&N air filter housing. A gasket is then installed onto the K&N mass air sensor adapter. The mass air sensor itself is removed from the factory air filter housing and installed into the K&N adapter, which is subsequently installed onto the K&N intake tube.
Following the adapter installation, the new air filter housing is mounted to the inner fender or core support. A coupling hose is then installed onto the throttle body and secured with a provided hose clamp. The intake tube is connected to the coupler at the throttle body and to the filter adapter. The tube is secured to the filter adapter with provided hardware and to the coupling hose with another provided hose clamp.
Final Connections and Filter Installation
The installation process continues with the installation of the K&N air filter onto the filter adapter, secured with a provided hose clamp. The EVAP and crankcase vent lines are then connected to the fittings installed into the K&N intake tube. Finally, the mass air sensor wiring harness, previously unhooked from the inner fender, is routed to the mass air sensor and reconnected. The K&N air filter housing lid is then installed onto the housing to complete the installation.
Performance Benefits
K&N states that its intake kits are guaranteed to increase horsepower and torque. Specific horsepower gains vary by vehicle model and are detailed in dyno charts available on individual product pages. The company emphasizes its expertise in cold air intake system development, design, and testing. K&N engineers utilize 3D-laser scanning to create precise models of engine bays and employ advanced technology to optimize airflow.
The design of a K&N cold air intake system focuses on maximizing airflow while providing engine protection. Air passes through a high-flow air filter, designed for outstanding engine protection, and then through an aerodynamically-engineered tubing system intended to minimize turbulence and heat.

K&N provides customer support for installation questions. Users can contact the customer service line or email [email protected] for assistance.
Conclusion
The installation of a K&N cold air intake system involves a series of carefully defined steps, from initial disconnection of vehicle components to the final securing of the new intake housing and filter. The process requires the removal of the factory intake, transfer of the mass air sensor, and connection of ventilation lines. K&N asserts that these systems are engineered to enhance engine performance by increasing horsepower and torque through optimized airflow and filtration. The company also offers support to assist with the installation process.
