Filter Maintenance:
The intake system should be cleaned at least once every three months; in dusty climates the filter
should be cleaned more often. Use a Prefilter to extend time between cleaning
. Cleaning the intake
is a two part process, the first part of the process involves the physical cleaning of the filter with soap
and water and the second part involves oiling the filter. To properly clean the filter, a Bully Dog clean-
ing kit should be used. Cleaning kits are available at any Bully Dog
dealer.
PART 1, CLEANING THE FILTER:
1. Remove filter from filter housing. Clean the filter housing if
necessary.
2. Begin the cleaning process by ridding the filter of any dirt by
lightly tapping it. Then brush away any loose particles with a
soft-bristle brush. This step can usually be avoided with the
use of a prefilter.
3. Spray cleaner generously over entire filter and let soak for
10 minutes.
4. Thoroughly rinse the filter with regular tap water (avoid
high-pressure hoses). Flush from the inside out or clean side
to the dirty side to prevent dirt from entering the filter.
5. Let the filter air dry before oiling, do not use any method to speed up the drying process. Using
a blow dryer or compressed air can cause the filter to disfigure which would then allow particles
to pass through the filter.
PART 2, OILING THE FILTER:
1. Apply a small amount of oil to the soft bristle brush and spread the oil over the filter. Be sure to
apply a small amount of force so not to damage the filter element.
2. Continue applying oil to the filter using a soft bristle brush until the entire filter is covered in an
even amount of oil, just enough to give the filter a solid blue color. Apply enough oil to make the
filter a solid and uniform blue, but do not go beyond that.
3. Allow oil to sit for 20 minutes. Re-oil any dry spots that appear. Do not oil filter excessively. Exces-
sive oiling can cause damage to intake sensors.
