Just ordered a K&N air filter.
 
Arrives early next week.

They're quite divisive. Some love 'em, some get angry at the lesser filtration they give.

I don't really care about the latter.

Will report back on real World difference.

I feel bad for you.

haha. But yeah good luck.

Previous owners had dirt going right through them and you could see the dirt on the other side of the filter.. If you ever see dirt, I'd avoid it like the plague. If you ride on all street and never see dirt, then yeah I wouldn't see an issue besides other little particles going through.

Good luck and let us know how it turns out.

You'll need a dynamometer to measure the fraction of a HP difference... but if you ride at all on dusty gravel roads, you will definitely see the difference in the amount of crap that will get past the K&N filter and into the intake tract. I had a K&N on my '94 XR650L Dual Sport a number of years ago, and it did a piss poor job of dust filtration. Since then, all my XR's have Twin Air filters.

Don't expect a noticeable HP difference. Never see any dust. Had one for 2 yrs on my previous ride. No polar bears, penguins or nuns died.

The K&N hype is just that. Been there, done that.

There are better ways to increase HP.

Most won't own their CBR250R long enough to see any savings with the K&N air filter, compared to the cost of replacing the $10 OEM Honda air filter every 10,000 to 12,000 miles... you'd have to get to 50,000 to 60,000 miles before the K&N would start to pay for itself. And that's not considering the additional cost of the K&N filter oil or cleaner.

I have a KN filter with a dynajet. No problems here. Have left over 'recharge' from other filters.

I got mine used for about $25, so I am not complaining. Ive never had any issues with K&N filters or products when used as directed and properly maintained.

Polar bear killers.

How dare you.


A little $60 air filter, and people get upset over it. :D But but but what HP increase do you expect off that, huh, HUH?!?

Er none mate, it's a little $60 air filter. :D
