K and N Air FIlter---Need to rejet???

[FreekShow]

Im thinking about getting the K and N Air filter for my TB. Would I need to rejet??
:ermm:

no..now if you take off the lid its a different story but just a airfilter change you wont notice anything

You will more than likely need to rejet.

Performance mod = engine needing more fuel = rejet

nah you wont have to rejet it
like jumbo said as long as you keep the lid on a new filter will not cause you to rejet but then again it depends on what type filter it is
as long as you dont elimanate the airbox and you keep the lid on you will be fine

I was wondering the same thing...

But it does make since, filter swap, no re-jet, but if you take the lid off then you would. That sounds like it would be right.

i personally dont consider an airfilter by itself a performance mod....
