Got the mopar cai, holly cow that filters huge, anyway it looks cool, sounds awsome, mpg is a little better, but not sure about the power, I think I can tell some midrange improvement but actualy feels like I lost a little low end torque could just be me though. I think you can be fooled somtimes when it sounds louder you think your going faster. Overall pretty happy with it, I had to sell my 71 pick up so I used some of that money to buy the cai, helped the blues go away a little. I just put it in yesterday and am wondering if it takes a few days for the computor to make adjustments , anyone know
