I purchased this for a Honda CF150F. I live in Arizona and was looking for a filter that would both block fine dust and allow for good air flow. With the stock air filter, it didn't idle well and bogged down. This air filter is much better. The bike idles well, even cold, and is much more responsive.

The construction is very solid. It fit the mounting space perfectly. I have not used the motorcycle enough to see filtration results. I have two other K&N filtered vehicles, one a 1994 I've had since new. I believe this current filter will be as good as the other two K&N filters I have.
