K&N Filter

[newman7096]

Will a K&N air filter make any difference in performance on a standard GS?

its been measured, and no BHP gain, but owners say it feels like you get more midrange feeling ? - maybe a case of paid out and want something for the money feeling -- put one in my track day car and it didn't register one iota of difference on a dyno meter-- go figure;

Sod that idea then!

For the money they cost they are worth it IMHO.Plus you can clean them as often as you like takes ten minutes I do mine every 500 miles overkill I know, but I like to think I'm giving the bike maximum air.It's cheaper in the long run

K&Ns

there is no doubt that in the 'old days' K&Ns could add bhp, particularly to motors that had been breathed upon.
I think these days motor are far better engineered in the first place, so the gains will be much less (zero?).
K&Ns do score over paper air filters when dirty. The flow of a paper filter falls off when its starts getting dirt in it. K&Ns continue to flow, so their great for dusty conditions.
You can buy a cleaning fluid to soak then in. you then wash them out under a tap and dry. finally squirt special oil onto them.

The K&N filter is really a performance filter and lets in quite an amount of small particles that the paper one don't.

If you intend travelling on dirt roads a bit I would be extremely careful before putting a K&N filter on.

Unifilters from Uni Flow in Australia, manufacture what I think is the best compromise around. I believe that an oil bath air filter is the best and then the Unifilter is next, followed by paper filters. K&N filters do let a lot of air in and most racing bikes I've seen, run either them, or nothing.

This link will probably give you a fair bit of foam filter information:-

I thought it were an airline to blow it out then apply some of their oil?
