Fourtrak k&n air filter

Forum: 

I'm currently looking into getting a k&n air filter for my 97 fourtrak. (part number 38-9070). Has anyone fitted this and did it give anymore power?. Mine's running quite well but I could do with more pick-up with lower revs for towing. I know that original fit filters have the plastic swirl on them and the k&n doesn't, will this have any adverse affects in general.?

Thanks

It wont give you any more

It wont give you any more power as a diesel engine injects fuel into a surplus of air, this means if it is getting surplus air then why do you need any more.
