【K&N】Replacement Air Filter Review

Genuine K&N Air Filter for Suzuki GSX650F 2011

This GSX650F came in for a service which included air filter, oil filter and oil change. I decided to go for the K&N filter over the OEM one because you also have the ability to wash, re-oil and re-use these filters. I have never found them to be anything less than the quality of the standard OEM filters and do not have any less performance. As I said, these are reusable if you do it all correctly. This is replacing the OEM Suzuki one which came on the bike when the customer dropped it off. By the looks of it, it has rarely been changed. I dispair how some people manage to run bikes without the slightest notion of maintenance. Finding the correct filter for this bike was easy too, I checked on Webike website and this showed the models that fit each filter. Really easy. I had other items in my order and this then cut down the shipping over the entire order. I use EMS fast service which arrived at my door in 5 days. All the items were packaged really well and bubble wrap and air pockets were used to fill any space in the box. Webike even tape the outer box on all sides so nothing can get in or out. The filter arrived in perfect condition and did come pre-oiled which is also nice so you do not have to mess around the first time. Fitted in about half an hour total. The final result was perfect. A nice clean well oiled air filter ready for a few thousand miles to come. Thanks to Webike for doing a great job and providing a great service throughout. View detail

K&N filter for Yamaha MT09 Tracer

I do love a good day of maintenance. This time it was for my wife's MT09 Tracer. Full on oil filter, oil and air filter change. I decided to go for the K&N filter over the OEM one becasue you also have the ability to wash, re-oil and re-use these filters. I have never found them to be anything less than teh quality of the standard OEM filters and do not have any less performance. As I said, these are reusable if you do it all correctly. This is replacing the OEM Yamaha one which came on the bike when we got it. By the looks of it, it has never been changed, wow, I dispair how some people manage to run bikes without the slightest notion of maintenance. Finding the correct filter for my wife's bike was easy too, I checked on Webike website and this showed the models that fit each filter. Super easy. I had other items in my order and this then cut down the shipping over the entire order. I use EMS fast service which arrived at my door in 4-5 days, this time was 5 days but there was a weekend inbetween. All the items were packaged really well and bubble wrap and air pockets were used to fill any space in the box. Webike even tape the outer box on all sides so nothing can get in out. The grips arrived in perfect condition and fitted as I mentioned above in about half an hour total and that was including cleaning the surfaces and prepping everything. The final result was great, all stuck down really well and no sign or any corners peeling up. If you do it right the first time, follow the instructions this won't happen anyway. Very pleased with my order, a big thanks to Webike for doing a great job and providing a great service throughout. View detail

Along with rewriting the ROM!

It seems to be almost the same as YOSHIMURAK&N, and the price is cheaper here.
Engine response will be very good if done together with ROM rewriting. View detail

It is difficult to tell how effective it is.

This is a Replacement Air Filter, used on a CBR650F.
It can be used repeatedly by washing and applying Oil instead of the usual paper Type.

The intake volume is slightly higher than that of the NORMAL Filter, but its ability to remove Garbage is inferior.
However, even so, I recognize that the NORMAL performance should have a LARGE margin, so the intake volume should be increased within a safe range by cutting that amount.

Installation requires removing the Side cowl, Mid Cowl, and RearSide cowl before removing the Tank.

The air cleaner is made Tight and must be pushed in firmly so that the edge does not float.
SealGrease looks Large sturdy without application, but if you have it, you should apply it.


After the replacement, I test drove about 50 km.
I don't feel that the blow up and the sense of power have improved, but honestly, I felt that if I said it was a Brush-boat, that's all I could say.

Considering that HondaOEMAir cleaner costs a little over 2,000 yen, it would be worth it after 5 OEM replacements.
If the mileage is high and the air cleaner is changed frequently, it is possible, but if you read the description of this filter, it is stated that it is Large sturdy for about 80,000 km without modification, so if you follow that, you will not get the original cost.

I think it is possible if you want to replace the air cleaner every 6 months to a year.

Another reason I purchased the filter is that I use K&N filters in my car and can use the filter oil and cleaner. View detail
