I just bought a k&n filter for my 04 raptor 350. I'm a little concerned because it doesn't fit as well as i'd like and im worried about it messing up my engine. it fits really snug (which is not nessassarly a bad thing) but it looks like that will mess up the gasket. i don't want to tear it up now! is there some kind of conversion kit i need or some other way to fix this prob. if anybody knows anything about this please let me know! thanks.

 

is this the clamp on with the thing that slides into the filter thing.. or is it a clamp on onto the carb?

 

The K&N drop-in filters are crap on the raptor 350, they just don't fit right no matter what you do because they have a poorly designed seal that is too thick. You should have sprung for a k&n clamp-on kit instead, yamaha's airbox design is severely flawed compared to a simple clamp-on filter.

 

hey recon.. i am thinking of modifying my airbox to accept a basic clamp on filter... as well as get the same airflow as running just a regular filter...
