Hello Im a newbie.
I ve recently installed a KN intake filter but instead of running better my civic is slower! much more slower!! Any Idea whats going on?

Is it a drop in filter? You can try resetting your ecu. Disconnect the battery, and then press the brake pedal to get the extra current out. Leave it for 5 minutes, then turn your car on, and let it idle for 5 minutes, and DONT touch the gas. It may not work, but its worth a try.

i would assume that you got an intake system, and that your car is running slower on the bottom end, and if that is the case...thats just what happens when you get an intake...they make your bottom end go to shit but give you high RPM HP
