 More Details:

The Outlaw High Performance filter offers many features not found in standard paper filters. Outstanding performance is obtained by their high flow rates, magnetic pre-filtering, consistent filtering medium, billet outer housing which aids in cooling the oil, and a unique progressive rate bypass which avoids unfiltered oil bypassing the filter at startup, and high-rpm operation — a major concern with standard paper filters.

At the heart of the filter is a medical grade 304 stainless-steel micronic cloth filter designed to pass a large volume of oil when compared to standard paper filters. The cloth is designed to filter out particles 35 microns or larger. (35 microns is below the limit of human visibility)

Before you start with the, “my filter is rated at 5 microns and it filters way better,” you need to understand just how the micron rating applies to oil filters.  The HD OEM filters and aftermarket paper filters are rated on averages, percentages and multiple passes, so a 10-micron-rated paper filter may be letting particles 100 microns and larger through. The medical grade stainless steel cloth they use in their filters is consistent across the entire surface and is rated at 35 microns, meaning nothing larger than 35 microns will pass through the material, it is an absolute, with paper filters, the rating is an average.  Additionally, paper filters have a bypass, so on startup & high RPM the oil is not being filtered at all!

Easy to remove with a wrench or a socket.  Cleaning the filter & the housing is easy- wash the stainless steel element in cleaning solvent, gasoline, kerosene, carburetor cleaner or any other degreasing agent.  Let air dry, or you can use compressed air.

There are two quad rings included.  A quad ring will typically last 3-5 oil changes.  Additional quad rings are available.  If you accidentally damage the stainless steel element, those are also available.

Because of the HiFlow characteristics of this Oil Filter, resulting in less oil pump drag, Dyno Runs consistently show an increase of 4-8 HP and an increase of 4-12 ft. lbs in Torque (Twin Cams). 

Quote from Hot Bike Magazine:

"Besides doing a superior job of cleaning and cooling the oil, independent testers doing back-to-back dyno comparisons of these reusable oil filters and an ordinary disposable, charted as much as an 8-horsepower bump along with 10 more lb-ft of torque."

Fits All Harley's 1986-Up (Sportster, Twin Cam, Milwaukee-Eight, Big Twin Evo)*

*Does not fit 1986 FXWG, FXSB, FXEF

"Not only did it cool down my 103, I gained 7 Horsepower & 11 ft lbs of Torque!" -Kevin

Good quality product. Prompt shipping. Review by Fltrxrider
Very nicely made, looks good on bike. Shipped quickly, easy installation. A bit pricey, but should last forever. Happy with this purchase, would buy from DK again. (Posted on 3/7/2022)
Awesome oil filter Review by Danny
This thing looks great. It’s easy to install, and even without a relocation kit, there’s more room to catch the used oil when removing. Cleaning is a breeze too. I can also tell a slight improvement in performance. Great investment. I’ve already convinced some of my friends to get one for their bikes. (Posted on 3/5/2022)
Quality Product Review by Stephen Wood
Love the look and reusability of this filter. The quality of manufacture is excellent and adding it with the relocation kit, I couldn't be happier "It's not just an oil filter" (Posted on 2/4/2022)

'way back there' in my rear view mirrors Review by Lee
The filter went on easy and looks great. I bought the polished aluminum filter to go with my bike's chrome. I see more distant vehicles 'way back there' in my rear view mirrors upon acceleration than ever before! Thanks again, (Posted on 10/30/2020)
We shall see Review by Wrench
I’m certain this is going to be a great product with all the research you guys put into everything. Just a bit upset with USPS and the 3-1/2 week delivery. Supposed to be half that ha but not DK’s mess up. So far everything I’ve purchased from DK has been spot on and reliable! (Posted on 10/12/2020)
Fantastic Review by Bill
Easy to install... great quality, machining and build, i noticed an immediate torque increase on my first ride after installing it... engine seems to run freer, revs quicker, more power is definitely noticeable... great product! (Posted on 8/29/2020)
Perfect Complement to the Clean and Cool Review by Fuzzy
Originally purchased just the cool and clean. Added this filter as an add to that. It's a perfect compliment that completes the Upgrade. Cools, cleans, increases flow, and pays for itself over time. Easily taken apart to clean, even has a permanent magnet to catch metal products. What more could you ask for? (Posted on 4/15/2020)
Outlaw oil filter/cooler Review by Vince
I purchased this product because of the research and testing that D K provides which shows that it is a better filter with less restriction, helps to cool the oil and less horsepower is needed to run the oil pump. It is well built and an easy install and cleanable so it should be the last filter I need to buy. Thank you DK! (Posted on 4/2/2020)
Good quality Review by Tom
Great part that functions as an oil filter and an oil cooler. Way better flow than paper oil filters. Buy it you won't be disappointed. (Posted on 7/29/2019)
Great Filter - Easy Install Review by Harry
I bought this re-usable filter along with an adapter kit for my 2017 Road Glide from DK. It has a high quality billet case and the filter is easily removed and cleaned/reused. What more could you ask for? Oh and it keeps your oil cooler. Win-win! (Posted on 7/29/2019)
