Well guys my delaer told me he would order me a K&N High Flow Air Filter for my 400i. I want to see how much more power it will give me. I hope it will give me some because it costs $49.95! We will see though. [img]i/expressions/face-icon-small-tongue.gif[/img]

 

Let us know if it makes any difference. I have the 400i too and have really thought about getting that filter.

Good luck.

 

wow, for $49.95 they had better do something more than give it a "little" power, don'tcha think, man, i used to think those things were only $39.95.... wonder how they went up so much?

 

Why the upgrade to the K & N? I realize they will give you a little more power, but do you guys feel that the 400 is down on power? Just curious....

 

I do want more power out of it.....

 

I put 1 on my 2000 500 and never noticed anything. I do like the idea of the precharger ...Bill
