TO START:

Turn off the ignition and disconnect the negative battery cable.
NOTE: Disconnecting the negative battery cable erases pre-programmed electronic memories.
Write down all memory settings before disconnecting the negative battery cable. Some radios will require an anti-theft code to be entered after the battery is reconnected. The anti-theft code is typically supplied with your owner’s manual. In the event your vehicles anti-theft code cannot be recovered, contact an authorized dealership to obtain your vehicles anti-theft code.
Disconnect the mass air sensor electrical connection and loosen the hose clamp that secures the factory intake tube to the air filter housing.
Depress the locking tab and then disconnect the CCV pipe from the plenum.
Depress the locking tap and then disconnect the CCV pipe from the solenoid attached to the factory intake tube. Disconnect the solenoid electrical connection.
Loosen the hose clamp that secures intake tube to the turbo inlet.
Remove the two bolts that secure the engine cover to the engine and then remove the cover from the vehicle. These bolts will be reused in a later step.
Remove the two nuts that secure the intake tube to the engine. Unhook the wiring harness from the intake tube and then remove the intake tube assembly from the vehicle. These nuts will be reused in a later step.
NOTE: K&N Engineering, Inc., recommends that customers do not discard factory air intake.
Using the factory bolts and the nuts provided, secure the two provided “Z” brackets to the engine cover as shown.
Install the engine cover onto the engine and secure the brackets to the factory mounting studs using the factory nuts.
Remove the upper air filter housing and remove the factory air filter.

Install the intake tube assembly into the coupler at the air filter housing and then into the coupler at the turbo inlet, adjust the tube for best fit and then secure with the provided hose clamps.

The C.A.R.B. exemption sticker, (attached), must be visible under the hood so that an emissions inspector can see it when the vehicle is required to be tested for emissions. California requires testing every two years, other states may vary.
K&N AIR FILTER MONITOR LIGHT: Some vehicles are equipped with a “Air Filter Monitor” system that will send a message to the instrument cluster indicating that the air filter needs to be replaced. This system is calibrated for the OEM intake system and air filter and will not be accurate when K&N products are in use. Always refer to WWW.KNFILTERS.COM for K&N air filter service procedures. This “Air Filter Monitor” system must be disabled to prevent the monitor from setting
on and causing a factory dealership visit to reset the system. Follow the “Air Filter Monitor” system procedure listed in the factory owners manual.
It will be necessary for all K&N® high flow intake systems to be checked periodically for realignment, clearance and tightening of all connections. Failure to follow the above instructions or proper maintenance may void warranty.

ROAD TESTING:

Start the engine with the transmission in neutral or park, and the parking brake engaged. Listen for air leaks or odd noises. For air leaks secure hoses and connections. For odd noises, find cause and repair before proceeding. This kit will function identically to the factory system except for being louder and much more responsive.
Test drive the vehicle. Listen for odd noises or rattles and fix as necessary.
If road test is fine, you can now enjoy the added power and performance from your kit.
. K&N Engineering, Inc., requires cleaning the intake system’s air filter element every 100,000 miles. When used in dusty or off-road environments, our filters will require cleaning more often. We recommend that you visually inspect your filter once every 25,000 miles to determine if the screen is still visible. When the screen is no longer visible some place on the filter element, it is time to clean it. To clean and re-oil, purchase our filter Recharger® service kit, part number 99-5050 or 99-5000 and follow the easy instructions.
