Bully Dog PreFilter (Part # 51200-8 for your intake)
The time between scheduled filter maintenance can be extended. Using a prefilter will prevent all
large debris from getting into the ribs of the filter. When using the prefilter, only fine dust particles
make it through the prefilter and onto the exterior of the filter. Thus when using a prefilter, scheduled
cleaning easy much easier and filter life is positively effected.
