For the price, I've considered the Arlen Ness Big Sucker and the Arlen Ness CheapShot fuel commander. I just need to know if all this is cost-effective... Would I get the same results from just replacing stock filter with a K&N? Or, should I go with a higher-end breather kit, like the BAK, or something?? No salesmen, please, just opinions and experiences. Thanks, again, y'all, for all your help.... I will also be adding V&H PowerShots, at the same time...
