Pusher Hollow Point Air Filter

We have designed, refined and tested our filter's geometry over several years - and across a broad range of conditions and vehicle configurations - to fine tune and perfect their durability. The inverted cone end cap maximizes filter media, catching more dirt and debris than other similarly sized filters.  Washable Oilable if needed (but not pre-oiled) Includes a fully stainless steel worm clamp for heavy duty hold Enhance your intake system with our optional pre-filter, designed to keep large debris—such as bugs, grass, and rocks—away from your filter, making maintenance even easier. Additionally, the pre-filter is semi-hydrophobic, causing water to bead and roll off, helping to keep your filter drier for improved longevity and performance. Frequently Asked Questions 1.

How often should I be cleaning my filter? We recommend you check it out every 5-6,000 miles; we find it easiest to just check on it at the same time we perform oil changes. Take it out, tap off any loose debris, dirt, bugs – then you can use your best judgement on whether or not it’s time for a full wash. Drivers in dustier, off-road conditions, will need to wash more often than city drivers. Click to read more: How to Clean Your Pusher Air Filter   3. Should I be oiling my filter? Is this filter pre-oiled? Our filters are made with media that can be oiled, but they are not pre-oiled. We don’t recommend oiling unless you are in a dusty environment and need the extra support of the oil to catch the really fine particles. If you do oil, make sure to use a cleaning and oil kit from a reputable brand, and take care to follow application instructions carefully to prevent over-oiling.   4. Do I need a pre-filter or filter sock? Enhance your intake system with our optional pre-filter, designed to keep large debris—such as bugs, grass, and rocks—away from your filter, making maintenance even easier. Additionally, the pre-filter is semi-hydrophobic, causing water to bead and roll off, helping to keep your filter drier for improved longevity and performance.   5. How long will these filters last, how many washes?   It really depends on your environment, how often you clean, and whether or not you use a pre-filter. If your filter media is beginning to get frayed or wrinkled, you might want to consider swapping in a new filter. With average use, this is normally after 2-3 years.
