It is the same filter as the CRF450R, and cost me $10.

 

As I stated a few posts ago, you can buy the K&N CRF450 filter from Rockymountain for $4.99 which is a superior filter to the OEM anyway.

 

why is the K&N better? I can see why their air filters are better, but why are their oil filters superior?

 

I'm sure the Honda OEM Filter is a good filter but K&N's area of expertise is filtering, air/oil. I'd much rather use a filter designed by a company that does nothing but design and manufacture oil filters than whoever Honda choose as the low bidder in building their OEM filters. Granted they would have had to be designed within Honda's tolerances but when a better filter is available at a cheaper price, I'll take that one all day long!

 

K&N OIL FILTER PART NUMBER FOR THE 450R IS ......#KN-115 ....JUST TO LET YOU KNOW
