You're off your rocker if you think just changing the air filter to a K&N & leaving the intake stock is the best thing.Im one of those people, who tested several intake systems and to me the best are the stock ones with the changes i mentioned! But in my K20 i use a AEM kai system! All depends one the aspiration of the engine and how many cubic centimeters of air you really need! My testings were always in NAs... never had a turbo to date so... i can only say that to NA engines (normally) it really is the best thing to use! Depends a lot...
My current car is N/A, & I can tell you that my V2 allows for much better performance than if I just strapped on a K&N filter....
