Anyone have a recommendation on a air filter for 09 sf? I have been browsing for the last half hour and can't find a supplier (USA).

 

I've been rotating a couple of Twin Air filters for about 2 years now. Work fine. Very noticeable performance upgrade from stock. I oil mine with Motul Filter Oil.
I'm using the KX500 model filter BTW, fits fine.

Just got a new No Toil filter so I'll give it a go this WE.

 

+1 on the NoToil filter. Believe it was for the KLX300.

I'd like to get a twinair thats flame resistant so I can pull the back fire screen. Got the kx500 uni filter & always grease the lip.

 

Twin Air filter and thousands of KM, no back fire screen. Never had a problem.

 

K&N all the way!

 

Ignition filters are inexpensive, and come preoiled with Notoil.
