CLEANING INSTRUCTIONS
When your cabin air lter(s) get dirty, the lter can be cleaned and reused. K&N® recommends
servicing your K&N® cabin air lter every 12 months or 12,000 miles. Best of all, the lter
comes with a 10 year/Million mile limited warranty. Servicing your K&N® cabin air lter is
simple: just follow the following 6 steps.
1.REMOVE FILTER: Remove the K&N® cabin air lter
from the cabin air lter housing and or cabin air lter tray.
Handling with care, remove loose dirt and debris from the
lter by tapping it with your hand or against a hard surface.
2. APPLY CLEANER: Spray a generous amount of K&N’s
specially formulated cabin air lter cleaner P/N 99-0650
onto both sides of the lter, with a majority of it applied to
the dirty side. Allow the cleaner to soak in for 10 minutes.
Do not allow the cleaner to dry on the cabin air lter.
5. REFRESHING: Apply K&N® cabin air lter Refresher™
P/N 99-0660 onto the cabin air lter element. Apply liberally,
so that the entire area of the cabin air lter media is treated.
3. RINSE FILTER: Rinse o the lter element with cool or
warm (not hot) water from the clean side out in order to
ush the dirt out of the lter. It may be necessary to use
your ngers on the hose, to apply light water pressure.
Repeat steps 2 and 3, until the water owing through the
media is completely clear of any dirt and debris.
4. DRY: After rinsing, gently shake o excess water. Allow
lter to dry naturally for 20-30 minutes. The lter does not

housing or tray. Follow original installation instructions that

is the only approved procedure for servicing your K&N® cabin air lter. Please visit knlters.com for a complete
