DK Customs 606 Air Cleaner Install on my FXLRS - High Flow Filter Element!

[@streetsean]

I did the 606 on my sport glide last week. It works great and I noticed a difference right away when I took it out with just the powervision canned tune.

[@RidinDad]

Awesome. That filter element is night and day from a lot of them obviously including the one I had. It’s a very straightforward and symbol design and it’s honestly pretty cheap compared to a lot of other air cleaners

[@streetsean]

Ooooo lol yeah it was much cheaper in bald eagles over here lol

[@jasonsanderson9385]

@@RidinDad I currently have to Trask filter as well with the clear so you can see the throttle body....... Aesthetically it looks great it does come out pretty far, I had the same highway bars as you except mine is Sk8bar (same ideas Bung King but it has skateboard wheels on the end opposed to sliders) I find it difficult to put my right leg up comfortably.. would you say your new filter setup is not out as far?.... I'm currently looking to switch mine out haven't decided what direction to go. Possibly the S&S stealth mini, Arlen Ness Velocity 65°..... I'm going to check out the link you have in the description... Definitely post a review on how you like it

[@RidinDad]

Yes absolutely. It’s probably about half of the width sticking out from the bike as the Trask was. So if that is your concern this will definitely be a huge upgrade for you

[@1jrlord17]

Info was great on the Trask filter element. I just ordered the K&N off Amazon. I'll be swapping it out tomorrow as soon as it arrives.

I found DK customs when I had my first bike, a 2020 iron 883, and put a stage 1 on it from their stuff. A 587 air cleaner, catch can, and a set of vieds which take the place of an expensive tuner. The difference was immediately noticeable! Then a set of slip ons and WOW! That bike absolutely came to life! In all I spent less than 1k on my stage 1 and got such great results that I was shocked. Now I just traded in for my’21 FXLRS and you can believe that I won’t be using anyone but DK for my performance stuff. Not unless someone can give me a really good reason to spend more money and get less results? I’m just totally sold on DK after trying their parts and literally getting better results than they even advertised. Love DK customs!

Awesome! They do their research for sure!

just wondering if you cross referenced the trask air filter with a K&N filter the same size. you would get great look and same big numbers. Unless I missed something. Great videos by the way.

[@YODAMOBBIN]

Did you look into getting a different air filter for the trask that k&n makes or another aftermarket company?

[@RidinDad]

I searched a ton and I couldn't find anything because Trasks filter is unique to them. It has that small groove in it for the window front and has to be a precise width for their cover bolts too

[@samcannons8491]

Arlen ness method air cleaner has a built in system for blow by and looks as good as the trask, did you consider these ?

[@RidinDad]

I did consider them. The main thing that kept me from going with them was i could not see what their breather system looked like. I was unable to see any pictures and I wanted to know what exact style of external breather system was used because the pics anywhere didn’t show it. I also knew for a fact dk used k&n which was a big selling point

[@airvine91]

Would you consider using the Transformer EBS plate for the outlaw cleaner? That's what I'm going for. Was told the Transformer backplate would add to that velocity stack effect on the existing filter. Plus it's and external breather system

[@RidinDad]

Yeah man. I think they would work great together

[@darthmaul7428]

What are your thoughts on the low rider st? In my opinion, it is the only bike of the three that is a "sport touring".

[@RidinDad]

Yeah, it definitely fits that sport touring niche. I do not love the bags, they are uneven and they are somewhat small but the styling definitely looks nice and I really am not a fan of the faring but I am a fan that Harley somewhat listened to what their customer base was looking for I just think they’re styling it somewhat off. But I do appreciate the effort

[@JACampbell30]

Just recently stumbled on your page, great videos by the way! I just sold my Sporster and bought a bone stock ‘21 Sport Glide and am looking to put on an air cleaner. I LOVE the way the Trask looks but it looks like it will severely protrude from the bike and hit my shin with the Sport Glide’s forward controls. I am also looking at the DK 606 air cleaner as well as I’ve had really good luck with their products. Apart from the looks of the 606 any complaints? And any thoughts on whether the Trask would hit my shin with forward controls? I’m 5’10” for reference. And I can’t find dyno numbers on the Trask anywhere, any opinion on the “feel” in power difference between the two? Thanks for your videos!

[@RidinDad]

I’ve posted updates on my bike about power. Stock vs stock, the dk is much better for performance. The stock trask filter is super thick and sucks. I currently put the trask back on with a k&n filter that’s a direct drop in replacement. If you’re not doing any motor work I’m pretty sure either air cleaner will be fine. Trask sticks out more. I think it would definitely hit your leg or knee at least. It hits mine a tiny amount with mids and I’m 5 08. Dk is a great product for a good price. Good guys there too

[@hitituprohb]

Trask is known for their turbos. I can imagine when you're forcing induction filtration is more important than free flow.

[@RidinDad]

Yes, that’s true, but if you look at their turbo set ups they don’t use that filter and it’s just a solid metal piece instead of the filter element since air passes from the turbo and not the filter. Completely different set up so I understand what you are talking about but it’s a completely different setup

[@FXFBS23]

Ridin Dad: First, I hope things are going well with your home remediation. Second, thank you for making this video. I am looking to replace stock AC on my '23 Fat Bob. I was going to buy the DK 606/with EBS like you, but then I saw you went back to Trask with a custom cover. Did you keep the K&N filter? DId you replace the DK EBS with the Trask EBS? I could not find a video explaining why, although I knew you wanted a custom AC cover and, I love the Trask see-thru as well. So I was thinking a Trask AC with and Trask EBS should work. But what about the paper filter element? You said the Trask was too thick. Appreciate your thoughts if you have the time. Thank you

[@RidinDad]

Yeah I just love the way the trask looks over the dk. I use the k&n filter with the trask now. Trask ebs too since it’s designed to work with the trask. The k&n filter I have is a drop in for the trask that replaces the stock filter. It’s much more breathable and much better. I have the link in one of my comments on the trask videos

[@RidinDad]

If you have a stock bike I’m sure the stock trask setup is fine for you

[@FXFBS23]

Thank you! My bike is stock right now except for some S&S grand national slip-ons that was done when I left the dealer. Just to hold me over until I can do all my mods. Again, Thank you for taking the time to quickly reply. Hope to see you on your channel soon. 👊

Very seriously debating getting rid of my trask air cleaner and looking into DK again. I was looking into them first but trask's clear window drew me to them more and plus they're local..

@@RidinDad will it fit my 19 road glide?

[@RidinDad]

I’m not sure offhand. If you go to the website and check it out just let me know and we can talk. I think it will because the other filter that I just sold from my buddies was compatible with softails and touring bikes. So I believe so but double check

[@robbyclark6915]

Btw, DK says the 636 (elbow shaped one) has the absolute best performance numbers for the M8 platform according to their dyno tests. That’s the one I’m going with here in a couple months.

Any updates on how you like it? Looking to get a 587 or 606. I’ve got headers and new slip ons ordered. Currently running Arlen Ness, slip ons with a cam. Road Glide.

[@RidinDad]

So I had it on for several weeks and I liked it. Worked fine and did not leak oil from any of the joints for the external breather system. I just did not love the look of it and ultimately I went back to the Trask with one major change. I did a lot of researching and trial and error with some Amazon orders and I actually found the exact drop in filter replacement from K & N for the Trask filter element. I have not put it on a dyno to confirm, but based on the quality of the filter media I would assume it does just as good as the DK and I would imagine only a loss of one or 2 hp with the filter on.

I wonder how Fuelmoto Typhoon 1” air cleaner compares to your D&K air cleaner

Probably around the same for this build. I would imagine any air filter without a genuine K and N filter element or at least one that breathes just as well would perform a little bit less especially with the bigger bore builds

No no noticeable power difference from the butt dyno. However I did a lot of googling and actually found a k&n for the Trask! I’ve been running it with the filter for a few weeks and it’s a perfect t fit. No issues. I haven’t abs won’t probably dyno it again with the new filter on the Trask just for price reasons.

I appreciate that Harley listened to what we want but I don’t like it that much. I like the design of the sport glide bags minus that they’re two different sizes. I do not like the fairing at all really. I think it’s pretty ugly for the most part. The 117 I don’t care about. Barely different from the 114 and same stroke so end results for big bores are the exact same

[@CAT3616G]

I don’t know for bike applications but it’s well known for automotive engines that K&N’s are junk if you’re actually concerned about keeping dust and debris out of your engine. Filters are supposed to filter so there’s gonna be a trade off in some performance.

[@RidinDad]

I’ve seen nothing but the opposite of that. Where are you getting this information from?

[@CAT3616G]

@@RidinDad just do some reading on forums and some searching on KZbin regarding K&N filters and engine damage, there’s a lot of info. A high flow air filter of the same size is always gonna be less more porous to allow more air but it will also allow more particles and debris. The only way to filter well and allow more air is to use a much bigger air filter due to more surface area. It makes sense when you think about it.

[@RidinDad]

It does but I’ve never seen that about the k&n’s. I’ll look in to it in the car sector but I’ve seen the opposite on bikes. I e never heard of them being an issue in any way

[@richardrussell500]

@@RidinDad I have discussed this with DK personnel... I have been building hotrods for decades. the rule of thumb in that industry is that you DO NOT use Teflon tape for fuel or oil lines. period. no questions asked. I have seen engines destroyed because a piece of that Teflon tape broke off the bolt and entered the oil passages starving the engine of oil. I have also seen engines destroyed from Teflon tape braking off and entering the fuel system causing a lean situation resulting in burned internals. an old mechanic in my earlier years told me that Teflon tape should only be used for water and natural gas when plumbing a house. it should NEVER be used to plumb a vehicle. another problem is that many people do not know which direction to wrap the tape. wrapping it in the wrong direction will cause it to bunch up. any hoot, thanks for the content. I always enjoy your perspective : - )

[@RidinDad]

Yeah, I completely understand. I’ve seen a bunch of people wrap it incorrectly and adjust unravels as they are trying to tighten their set up. I will say for this specific application, though, those are one way valves, and designed not to let anything inside of the engine, if they’d allowed stuff inside of the engine, there would be more issues than having a small amount of Teflon tape in there

@@RidinDad my DK Customs oil relocation kit came with Teflon taped NPT fittings... from the underside, I found that tape extruding through the fitting/opening. if any of that tape broke off it would have entered my oiling system.
