K&N Aircharger on 2008 Impala SS
I really like this intake. It is made very well and I did notice a slight improvement in acceleration especially past 4k RPMs. The sound that comes from the throttle body thru this is amazing, sounds like a jet sucking air. 4 stars because although easy to instal it is time consuming. I'm a competent mechanic and it took probably 2hrs and its expensive.
