2006 F4i Power up
 

Pretty happy with ol yeller, but wondered if a K & N filter would give an increase in HP, however small. I assume it already has a ram air, so there is nothing out there to buy, to increase forced air (cold air intake) like with cars and trucks???

P.S. Already have TRS carbon exhaust and power chip.

ive heard that sometimes the stock filter works better. also you could always get a powercommander (im not sure what you are refering too when you say power chip) also what about velocity stacks . use the search option an dim sure you can find a lot of different ways to power up your bike. also you could just change the gears so it feels like it was more power

and on a side note . use www.photobucket.com to upload your picture for your signature ;)

I have a K&N and TRS slip-on on my F4i but didn't really notice that much of a change. I thought it got a little more reponsive but maybe that is my imagination. Only a dyno will tell me for sure. I'd be surprised if I have any added horsepower because of those two mods. I don't expect to really see any difference until I get a power commander as HAVOC stated.
