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.​

2. Rotate the crankcase vent hose locking rings

ROAD TESTING:

1. 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.

2. Test drive the vehicle. Listen for odd noises or
rattles and fix as necessary.

3. If road test is fine, you can now enjoy the added
power and performance from your kit.

4. 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.
