The Pusher 40 CAL Hollow Point Air Filter is the massive air filter included in all of the Pusher Cold Air Intakes for the Dodge/RAM Cummins equipped trucks. Massive 9 inch long washable air filter. This filter geometry was tested for several years in a broad range of conditions and vehicle configurations to fine tune it's durability. The overall sizing of this filter is used in all of the currently available Pusher Intake sysems for Ford Powerstroke meaning it can flow more than any 4" inlet charger can and has plenty of room to spare for dirt build up. Thanks to its inverted cone end cap this filter offers ample filter media. This is also a great filter for custom applications using 4" tube where a large filter is needed. Full stainless worm drive clamp included. 11" OAL X 8" OD base X 6" OD end cap X 4" ID flange.

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.
  2. 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.
  3. Do I need a pre-filter, or filter sock? Pre-filters are great at keeping large debris like bugs, grass, rocks, etc, out of your pleats, which makes maintenance even easier. Our pre-filter is also semi-hydrophobic, so when water hits it a good amount of that water beads and rolls off, keeping your filter drier which is best for longevity and performance. The airflow impendence of the pre-filter is negligible.
  4. 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.

Authentic Docs for great price!
The boots I purchased were Chelsea 2976 in Nappa leather (not the brown Crazy Horse, but the Black; such nice and soft leather!) and unisex size men's 7/women's 8/EU 39 (I'm normally a women's US 9/EU 40, but that's what fit best--see notes on sizing below). Considering the price, I was a little skeptical that these were genuinely Dr. Marten's, so I ended up bring them into a store to verify before wearing them--and multiple salespeople, who had worked for the company for 7+ years, said they looked like the real deal to them, which is amazing for the price (I got them when they were $99 online, but $160 in store; may have been a sale...?). Before ordering, I also visited the store to get the right sizing--Dr. Marten's doesn't sell my normal size in the US (EU 40), so I needed help figuring out what to buy. In the end that was either a women's EU 41 or a unisex 39. Dr. Marten's women's sizes are cut more narrow, so if purchasing women's, I needed a longer shoe to give my toes more space (EU 41, which they say is a women's US 9 but on many shoes EU 41 is a US 9.5 or even US 10). Unisex sizes are wider, so I was fine with a shorter length (EU 39). In the end, the only real difference between the women's sizing and men's sizing on the Chelsea boot was at the ankle; for some reason, the women's 41 had more of a gap at the ankle and I worried that might make it rub/blister more, so I went with unisex sizing. It might also depend on the boot, so I'd say go to the store for sizing before purchasing online. Once I got them & verified their authenticity, I got a but of things to help with weatherizing them and breaking them in (Dr. Marten's has a great kit! And, double thick socks). I did get a bad blister wearing them too long & uphill on the first day (and I had to get used to their weight; I don't have many heavier shoes). But, I used Compeed patches for the blister (should have put them on to prevent, but it was fine once they were on) and after a week of wearing them a little bit at a time, they are now super comfortable and I love them! Highly recommend!

Function and style
Size: 11 Women/10 Men, Color: Black Blizzard Wp
Ideal boot for the winter, snow, mud, etc. Protect your feet beautifully, stylishly. Tip: Wear with two socks to help break in for the first couple weeks. If you are a half size, round up. This is the model without laces, makes for easy slip on / slip off for those pesky people who insist on having you take off your shoes at their house! Ha ha, you know who you are.

Size up for a little bit of heel slip
Size: 9 Women/8 Men, Color: Black Nappa
It’s still a doc and the air sole with bottom out kinda quick but it’s comfortable at first. Size up for a little bit of heel slip so you don’t get heel blisters but not too big of a size jump. Think of it kind of like a cowboy boot size

Comfy, don't require "breaking in"
Size: 8 Women/7 Men, Color: Dark Brown Valor Wp
Great fit, and both my pairs of Chelsea boots required way less breaking in than other Dr. Martens I own. Hold up to frequent use and I love the fleece lining for colder days.
