【K&N】Custom Air Filter Round Taper Type Review

No doubt in terms of performance.

We selected this one due to its dimensions for the production of a custom motorcycle.
Unlike cheaper Power Filters, there is no doubt about the filtration performance, intake resistance, and other performance aspects, but I always wish the rubber part was a little better finished.
Oil should be applied in small amounts in high places and allowed to permeate gradually by gravity, and should not be sprinkled over the entire area from the beginning (over-application). View detail

Good appearance. Performance has not yet been experienced.

I put it on a GOOSE 350.
It replaced the Air cleanerBox that was taking up Space.
If I try to remove the existing Air cleaner, I have to remove both the carburetor and the Indicator, which is a hassle.
But I changed it to this guy and Refreshing.
The intake efficiency is also increased, so the jet and needle are changed and the ignition is ready to go.
Idling is unstable, but when I give it a push, it turns smoothly. However, when I turned the Axel back on, the engine stopped.
Oh dear - another carburetor breakdown.
When I carburetorRose, I think Dust or something got in there and clogged up the Pilot.
So, I have not been able to experience it yet. View detail

Air Filter Round Taper Type from K&N

* About quality and texture, A pleated cotton cleanable pod style air filter and nicely finished chrome end piece. * About the feeling of use, This air filter was used in the creation of a custom air intake for a Monkey 125. Has performed as intended and looks good while doing it. * Products to buy together, Since the K&N air filter's location allows it to be exposed to the rain, then a K&N pre-charge cover is a great idea at add for a little water resistance. * Difficulty of installation, Installation is just positioning the air filter on the intake pipe and securing down the included hose clamp. The process was completed in 2 minutes with no difficultly. * Cost performance and comparison with other products, The K&N air filter is more pricey to purchase then most pod style air filter but they do state they have a lifetime use design. So if maintained will last you much longer and end up cheaper then constantly purchasing disposable paper air filters. * About shipping and packaging, I am happy to wait 6 weeks on average for my parts to arrive in Sydney Australia via Webike's sea freight which comes with tracking and insurance so I know I'm covered in case something was to go wrong but with there outstanding bubble wrapping and boxing there have been no problems. * Any concerns, cautions, or advice when purchasing, If you a researching a particular size air filter for a custom intake you can use the K&N website to assist with measurements. Use the product reviews to assist in making a decision on your purchase. View detail

Installed on KEIHINPC20

I use a PC20carburetor on my 4MINI and I combined it with K&N's air filter.
I did not use the Filter oil that came with it.
The reason was that the Carburetor setting was about to change.
Compared to the Sponge type air filter, the intake noise during acceleration will be a little quieter.
In terms of performance, it will extend a little at high rpm. View detail

It will last a very long time if you keep up with the Maintenance.

I've been using it for 2 and a half years since I bought it, and Rubber hasn't deteriorated at all.
If you do maintenance well, you can use it for a very long time.
Although the initial cost is high, the Power Filter from Zitna and Zekegawa is the best choice.
It's a small price to pay when compared to the cracked and shabby appearance of Rubber in a few months.

If you buy the large capacity detergent and oil for maintenance, you can use it a lot of times.
I can highly recommend this product as its performance is proven. View detail
