Naked Complete HiFlow 606 Air Cleaner Harley Milwaukee-Eight Review by Bob
Replaced the screaming eagle high flow air filter with this one so I could use the transformer and i am so glad I did. It seems like the engine runs better and throttle response is quicker too.

Great product and worth the money. (Posted on 5/9/2023)

Excellent way to complete stage 1 Review by NK Bobcat
I already had the breather bolts and a high flow air cleaner from Vance & Hines. I liked the idea of using the OEM cover so the breather bolts were covered and the steam and blowback wouldn't hit my leg. My bike looks and runs great and I have had no oil or blowback through the breather bolts. (Posted on 4/30/2023)

Naked complete HiFlow 606 air cleaner HD M8 Review by Kerry
I love this combo set for 3 reasons, first, it allowed me to use my H-D military air cleaner on my 2018 Trike! Second, it gives better airflow. Third, with the EBS it keeps heat and carbon build-up down.
The easy instructions and U-Tube videos make the installation quite trouble-free. (Posted on 4/6/2023)

Great product! Review by David
Love the fact that I could use my OEM cover since I had the cover painted to match my bike. (Posted on 1/20/2023)

Love it! Review by Nevin Pratt
I wanted a quality hi-flow air cleaner, but I wanted the stock look. This one (with the original cover plate) was just the ticket! (Posted on 10/17/2022)

Nice Setup Review by Bill
2020 Roadglide Limited. Running the factory airbox cover for now while looking for a custom cover. It does stick out a little more than the stock location. I was able to reduce that some by deleting the 3 spacers on the mounting bracket. I had to grind some off the bracket so it sits flat on the filter plate. Also I used the provided cover screw to plug the center hole in the plate. (Posted on 9/22/2022)

Awesome air cleaner kit! Review by Bobb Gorena
Really easy to install, although because the intake is asymmetrical, you have to make sure everything is aligned properly. The pictures help a lot. It makes a huge difference compared to the factory air box, and coupled with the external breather my bike is running lots better, with better throttle response, better sound, and more get up and go!! This is a very high quality component, at a great price! I bought it to use with the stock cover, but I think it looks pretty awesome naked, plus it sounds so awesome sucking in all that air when you open up the throttle! Couldn't be more pleased! I'm a customer for life now! (Posted on 5/7/2022)

noticeable performance increase Review by Jim
First of all let me say all quality parts as expected from DKCustoms. Easy install, printed instruction are good but I must say watch the video a few times before attempting installation. Also as stated in previous reviews it does make the OEM cover stick out a bit further. I have the rider floor board extensions so not a big deal. There was a noticeable increase in power and torque after putting this on. Really woke up the machine. As a side note there is a better sound coming from the exhaust also. Great product. Highly recommend. BTW I have a 2019 M8 114. (Posted on 3/30/2022)

Nice low profile AC Review by Sao
Had little issue with the first one and DK responded quickly and the second one was spot on like all DK products!! Great customer service this is a nice low profile AC running it naked with the HD ratchet cover. Thanks again! (Posted on 3/19/2022)

EXCELLENT - really delivers! Review by Kevin Z in Arabi
First off, I'm not a mechanic or "technician" as they are called today but I was easily able to do this install myself. The naked air cleaner and discrete EBS system look great on the bike and from the "seat of the pants" dyno it feels like my 2021 Triglide pulls much harder, faster. It took me one cold beverage and about two hours total, including showing it to a neighbor. The 114 is already strong but now pulls harder and no more hot oily mist being put into my intake and engine. I wish I could include a picture as the new 606 looks so much better than the stock cover, but if I want to go stealth mode can put the stock cover back on. EXCELLENT PRODUCT as is all that I have purchased from DK.
DK has a great video on the install and great customer service on the phone. I am extremely happy with spending my hard earned $$$ on DK products. (Posted on 3/15/2022)

Great air cleaner Review by Bob
Changing out the stock air cleaner isn't a hard choice to make and this is a great cleaner to go with. The only thing is if you're going to retain your M8 stock cover it will stock out slightly further with this filter. It's not too the point where it's uncomfortable, but it is noticeable. Even with that I'd highly recommend this air cleaner. (Posted on 2/28/2022)

Overall a great air cleaner with one minor issue Review by Tom
Overall, this is a great air cleaner. SUper easy install as expected, quality parts and perfect for adding a breather, which I bought from DK also.

The one issue I have is the way the OEM M* air cleaner cover sticks. I like the look of this cover and wanted to stay with it. This is not necessarily a DK Customs issue, you need to use the bracket to attach the OEM M8 cover, and to clear the hump on the K&N filter you need to install spacers, making it stick out a little more.

I would highly recommend this air cleaner if you are installing a breather. Get both of them from DK Customs. (Posted on 10/13/2021)

Have no doubts... Review by Ricardo
If you're on the fence about buying a complete air intake system from DK Customs; don't be. You won't regret the purchase. Excellent support, delivery and instructions on the install. My 2020 M8 feels stronger on 2K-3K RPM range and response is clean with added power.
Recommend getting the EBS with the system as this will prolong your engine without that dirty air getting back into it. Highly recommend. (Posted on 7/28/2021)

Easy mod with real benefits Review by Chris
Bought a used 2017 ultra limited. First oil change I noticed the air filter had oil all over it. Not knowing about the blow by was I did some research which eventually led me to DK customs. Bought the 606 naked kit so I could keep my stock cover. Watched the linked video once before the part arrived and followed along again while doing the install. Couldn’t have gone any easier. The bike feels more responsive and I’m not sure if this is a placebo but it seems like it sounds deeper now also. Long story short. The 606 kit is money well spent. Thank you DK Costums!!

I work as a Program Manager for MHEP Review by DREAD
THE QUALITY OF THE PRODUCT IS GTEAT. THE INSTRUCTIONS WERE NOT CLEAR TO ME WHEN IT CAME TO RE-USING THE STOCK AIR CLEANER COVER WITH MY 2017 TRI-GLIDE. BUT WHEN I CALLED DK THEY WERE VERY RESPONSBILE, KNOWLEDGABLE AND HELPFUL IN WALKING ME THROUGH ANY MISCONCEPTIONS I HAD. IT WAS MORE MY ANXIETY THAN THE INSTRUCTIONS. I'D RECOMMEND THIS PRODUCT TO RIDERS EXPERIENCING THIS OIL/MIST ISSUE OR NOT; IF IT AIN'T HAPPPERNING NOW, IT WILL EVENTUALLY HAPPEN SO WHY NOT PREPARE FOR THE WORST CASE SCENARIO AND TAKE SOME PREVENTIVE MEASURES FIRST!

Quality product Review by Randy C
Fast shipping. Fits well . All hardware needed included. The engine is much more responsive than stock of course. Used the stock AC cover. Also bought the breather kit that works great. I like this product. (Posted on 6/1/2021)

Excellent product, more power Review by HogWart
I bought this along with the external breather system mainly to avoid putting oil back into the intake air. I was very surprised to learn that there was a significant improvement in power! The stock exhaust also now has a nicer "growl" - even my riding buddies noticed this. It is well made and easy to install. DK even has a detailed video on YouTube that takes you through the process, step by step. Well done, DK!! (Posted on 4/22/2021)

Givin' the M8 some CPR Review by Wally
Put this on last month on my 2017 police bike, now she can at least run a full marathon without running out of air. Great addition. It does push the filter and cover out a bit but added the floorboard extensions. That helped with more room. (Posted on 3/23/2021)

Just a heads up Review by TBull
I bought & installed the “Naked Complete HiFlow 606 Air Cleaner Harley Milwaukee-Eight”, which reused my stock breather cover on my 107 M8. Not intending to be critical of the product, but it does move the breather back & out considerably. It now pushes my leg out more making it less comfortable for me.

Easy to install on 17 TG Review by Phil
Liked the looks of my 107 cover so with the naked high flow 606 I could reuse it. One thing to note though and that is that it sticks out farther. I will be ordering the foot feet extensions next. (Posted on 5/24/2020)

Easy Install - Not Symmetrical Review by Chris - Ohio
Bought this kit as I wanted the flexibility to reuse the stock A/C cover or to mount a center holed cover of my choice from HD at a later date. All in all, easy install, just like other A/C kits form DK. What I didn't know was how off center the circular naked a/c would look on the M8 vs the old Twin CAMs. This is not a knock on DK at all, just something to be aware of if going with a circular a/c kit from anyone really on an M8.

HDs twin CAMs are very symmetrical when it comes to adding a high flow a/c kit whereas the M8 is not. I never noticed this until I installed this kit. I almost prefer the look of the stock a/c cover over the naked filter by itself with how much it appears to be set forward on an M8. Hopefully I'll get used to it. (Posted on 12/2/2019)
