To be adjusted in the future
We had been considering removing the air cleaner box and replacing it with an OEM carburetor power filter due to the poor serviceability of the carburetor, but we were not satisfied with the results and decided to replace it with an external carburetor. However, I did not want to do that, because I was not satisfied with the results, and I might end up replacing it with an external carburetor, which would be very expensive, complicated and time-consuming to set up, and difficult to drive with. We didn't want to make it difficult to drive by increasing the power, so we decided to replace the air filter with a more efficient one.
Installation is not difficult at all, since all you have to do is open the lid of the air cleaner box and replace the inside contents. Naturally, the dimensions of the filter were Exactly the same as the air cleaner box.
After the replacement, I test drove the car for about 100 km and found that there was no particular change in the intake sound, etc., and unfortunately the bumpiness during deceleration was the same as before the replacement. However, I think the engine feels better than before when I pull the engine. The engine seemed to turn more comfortably during acceleration than before. However, the low RPM range became a little bumpy and the Idling became a little unstable.
There are still some issues, but with proper adjustment, I think I can solve the problems I am experiencing now. Compared to the NTB Air Filter I have been using, the price is more than three times that of the NTB Air Filter and about twice that of the OEM, but I am glad I bought this product. I am glad I bought it, because I am told that I can use it repeatedly if I take care of it, so I will use it for large projects.

Inhalation resistance seems to be quite low.
[How is it used?
The OEMFilter was getting dirty, so I upgraded it while replacing it.
Was the one you received as per Image?
The thickness of the top and bottom of the filter is about half that of the OEMFilter, and the number of folds in the filter is 17 compared to the OEM27. The OEMFilter seems to have poor inhalation and dust collection efficiency, partly because the folds are close together.
Was the installation difficult?
Before installing the filter, apply Sealing Grease from Included Parts:to the outer circumference of the filter, but since the filter is designed with almost no clearance, there is no wobble and it can be installed tightly and securely. Because the filter can be attached firmly, it seems to be large and strange when removing it. I also applied sealing grease to the groove on the reverse side of the air cleaner box lid to make sure it is airtight.
How was your experience with it?
My 390DUKE is fueled by a sub-computer (FuelXPro), which increases both Power and Torque, so I could not feel any obvious improvement in performance after replacing it with this DNAFilter. However, I was able to confirm that the fuel consumption improved, although it was only about 0.1 to 0.2 km/L.
[Included Parts:were they on?
1 pc. of Sealing Grease is included.
[Was there anything that disappointed you?
It is attached too tightly to the Air cleanerBox, so I am worried about breaking the Air cleanerBox when removing the Filter.
Other items that would be helpful
Points and hangs for installation:There are two claws for fixing the filter. I successfully installed the filter by pushing the claw part downward with a slotted screwdriver and hooking the claw part.
Availability and clarity of Instruction Manual:An Instruction Manual is included, but it did not describe how to fit the fixing jaws well.
Items to purchase together:Since this is the first time to use the DNAFilter, I also purchased the Service kit for FilterMaintenance (Item No. DSK-3001) at the same time.

It will be such a thing
Used on the 2022 MODEL ZX-25R SE.
For ZX-25R, there are almost two choices, MWR or DNA.
MWR seems to be efficient, but it seems that thin sponges are used and dust collection capacity is questionable.
Pass because the inside of the Engine is likely to be unusually dirty, though it will produce Power.
Then DNA is the only option, so I bought this one.
The installation was Large strange because the Cowl and Tank were removed.
The thing itself is only fixed with a single Screw.
After installation, I took a test drive and did not notice any change.
The ZX-25R itself has a thin and peaky Torque, so I don't think you will be able to feel the difference.
It will be OK if you get the satisfaction of having replaced the Parts.

Top quality Air Filter!
[How is it used?
Exhaust system was changed from NORMAL to YOSHIMURA's Hand BentShort, so the filter was also changed.
Was the one you received as per Image?
The box was larger than I expected. The product itself was ready to use right from the start with the Oil acclimated to the Filter.
Was the installation difficult?
I just need to remove the side cover and open the 3 screws on the lid of the Normal air cleaner and replace it, but it fits in the space of the Limit and requires a bit of hang.
How was your experience with it?
Intake was clearly better than at NORMAL.
Exhaust system replacement has also improved the exhaust system so that balance can be obtained. Therefore, the output has been increased and it became a good feeling.
[Included Parts:were they on?
Instruction Manual and Sticker were included.
[Was there anything that disappointed you?
The price is a bit high, although the maintenance kit is also included in the purchase, and even with the perpetual warranty, the Gold price is enough to buy another product from another company.
▼The effect is not as effective as DAYTONA's Filter, but the Cushion, which was not available in DAYTONA, is Quantity.:The product is set and carefully made. Since the company claims a lifetime warranty, I think they have absolute confidence in the materials of Sponge and Net.

Intake system modification
Purchased with the aim of eliminating CUB at low RPM.
After the replacement, the CUB was not eliminated, but the high-revving blow-off was much better!

Lifetime Warranty
We replaced our existing Filter because it was cheap and rotting.
The cheap ones have sponge parts and I worry about them falling apart, but this product has rubberized edges, so I don't think I have to worry about that.
I also like the reusability and the perpetual warranty.
May it last for a long time.
