i just installed a universal air intake and its running worse now than before. i bought a 3 inch adapter kit and and universal filter and hooked the adapter and filter up where the airbox lid was. whats the problem? thanks

 

Hmm... Did your air intake have plug where the two vacuum lines go? In addition to this, define "running worse"..

If you mean down on power, thats likely if its sucking hot air from under the hood (these engines especially t6 put out a lot of heat)..
