INSTALLATION INSTRUCTIONS

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 x as necessary.
3. If road test is ne, you can now enjoy the added
power and performance from your kit.
4. K&N Engineering, Inc., requires cleaning the
intake system’s air lter element every 100,000
miles. When used in dusty or off-road
environments, our lters will require cleaning more
often. We recommend that you visually inspect
your lter once every 25,000 miles to determine
if the screen is still visible. When the screen is no
longer visible some place on the lter element, it is
time to clean it. To clean and re-oil, purchase our
lter Recharger
®
service kit, part number 99-5050
or 99-5000 and follow the easy instructions.
