If you significantly improve the air flow, and you have a vacuum secondary carburetor, then you will need to recalibrate the spring/opening of your secondary system. There are a zillion threads out there where the enthusiast invests in a nice, new high-flowing K&N system and then complains that it has "robbed him of performance" and that the system sucks. He then puts back on his old system and shuts up. Of course, he was "robbed" because he effectively went from a four barrel carb to a two barrel carb.  |
