There were many reasons for the change of the site software, the biggest was security. The age of the old software also meant no server updates for certain programs. There are many benefits to the new software, one of the biggest is the mobile functionality. Ill fix up some stuff in the coming days, we'll also try to get some of the old addons back or the data imported back into the site like the garage. To create a thread or to reply with a post is basically the same as it was in the prior software. The default style of the site is light colored, but i temporarily added a darker colored style, to change you can find a link at the bottom of the site.
K&N AIR FILTER

Only have to buy it once and don't have to go to dealer. Is 3ppm of dirt a lot or should you do a test yourself to see how much dirt goes through on each air filter?

hmmmm
Guys maybe I am wrong, but with the K&N filter - if highly hypothetically, there is maybe, maybe a more dirt coming in, that means there is also more air going in.. right? so the bike breaths better, so the performance can bi slightly better.
has anyone experience better this or is it just placebo?

More flow does not necessarily mean more dirt. The K&N does flow more air. But it doesn't necessarily give the Spyder more power because the filter is not the biggest source of restriction on airflow. You have a restrictive exhaust, catalytic converter, etc. You would need to open up some of the other restrictions to really utilize the additional air flow capacity of the K&N air filter.
What the K&N does give you is a very long service interval and pretty much a lifetime filter. (as mentioned in another post above)

I have also felt K&N filters were a solid replacement for 30+ years but over the last five our so I have heard multiple horror stories on different forums from reputable members with catastrophic problems. I'm not sure what has happened because for a long time they were the go to air filter if you wanted a cleanable replacement filter.

My take is that people are getting something like the F250 7.3L Ford engine which you can pretty much double the HP and even more the torque. With the turbo sucking a tremendous amount of air I think some are overcoming the capabilities of the K&N design and pulling in unfiltered air. The K&N will flow a lot more air for the same surface area. But you really need to increase the surface area when you're modifying something as much as some of these turbo diesel guys are doing.
The Spyder is nowhere near that ball park. Not even close. In the Spyder you're not dealing with the same issues and you're not going to get any problems.
Another major brand of motorcycle offers K&N filters in their catalog as a warranty compatible performance aircleaner. So some people apparently have had trouble with a K&N filter but many others have not. The evidence and their million mile warranty offer would suggest they are in it for the long haul.
There is maintenance involved. As a conventional air filter ages it captures more particles at the trade off of increased pressure drop/lower engine performance. The K&N needs the oil to capture particles and needs periodic re-oiling.
An internal combustion engine is an air pump that converts heat to mechanical power. It is a system. Air in and air out are affected by the restrictions in the intake, internal to the engine, and the exhaust. Noise and other considerations add restriction to air flow through the system. Remove exhaust restriction will improve performance up to the limit of the next piece of the system. Generally to yield a performance increase, both the intake and the exhaust need to be upgraded. If you haven't changed and do not plan to change your exhaust, then the air cleaner element isn't going to offer much improvement in power.
If you don't like them, don't use them.

:agree: He's right, ya know. It's like arguing about what the best socks to run in are and not mentioning what sneakers you have. A filter is a moot point unless the back end is open to get the air out quicker... Only then does 'air in' matter significantly.
And I am still chuckling that I said "back end is open." :roflblack: I will always be 14 years old mentally. I'm good with that.

But Ron what am i suppose to do with my powerstroke RS.
Switch back to the original filter:roflblack::roflblack:

Just hang on! I've almost got your turbo kit ready to go! You might need a little fatter rear tire though! :thumbup:

So do I...
212,517km on my Cummins 5.9 with a K&N filter. Have been in sand storm going through Texas, in Mexican dust on my way down to Puerto Vallarta, and in dust storm in Arizona.... not talking about salt dust in Quebec during the winter dry days..... I wonder how many oem filters would have busted open in thoses situations..... except for the Quebec salty dust, all the others situations were pulling a 13,000lbs fifth wheel.... also had a K&N filter on my Avenger for 345,000km ..... engine was in excellent shape. The body was letting go.....after 14 years..... just my personal experience.

Thanks!
Sometimes, when it's all been said, you just have to laugh a little... :thumbup:
I'm new here, I have a month-old 2015 F-3 S, I put a K&N filter on it after a week. A thousand miles later, I can say there's not much discernable difference. There is a more pronounced "whoosh" sound under heavy acceleration. I plan on buying/installing the RLS Punisher exhaust next week or two. I am expecting noticeable gains at that point. I'll keep you posted
Ride safe��

These posts about K&N filters are funny.
I have been witnessing these types of post for over 20 years.
Do K&N filters blow up motors. Or no?
Well this is easy. If you have a K&N filter. And you clean it and oil it regularly and properly and you drive on normal roads or highways etc you will be fine. The K&N filters are an amazing product. And they would not still be in business after a million years if they blew up so many engines as people say they do.
Now that being said. If you drive on gravel roads all the time. Where it is dusty as ever. You need to clean your filter more often. And I mean often.
K&N filters are made to let air through. They are particularly made for racing where you usually don't have dust. (Yes depends what you're racing)
So this being said they do let some dust through. Especially if you are driving in above normal dusty conditions.
JC sounds like those engines you are talking about. They drove in dust all day long. And never did any maintenance on their filters. Regardless 10k miles. For some parts to be sandblasted this would never happen on normal roads. Even if you didn't have a filter.
So OP you need to ask yourself.....
Where do you drive?
How dusty/dirty is it when you ride?
Can you do your own maintenance on the filters?
Will you do maintenance on your filters?
IMO K&N filters are awesome for street vehicles. But poor for off road unless you are anal and literally clean your filter after every ride.
Maintenance will keep your machine alive. Not the type of filter you use.
