I am looking to install either a airflow, powerflow, K&N filter....in order to increase airflow. What are the differences between these options, and which is the best for everyday driving?
Thanks

 

You will see minimal power gains (and maybe even a loss) with any aftermarket intake - unless you combine it with other mods. All you are getting for your $100-250 is perhaps increased induction noise, but that may be enough reason to do it!

do yourself a favor and just get a bmc filter. If you must get a fabspeed or that type airbox kit, anything else looses hp. Although there is some new bmc canister filter deal that would probably satisfy you and actually work.
