Nice power boost, minimal or no gas mileage.
I got this for a little extra boost out of the 4 cyl in my Equinox. I definitely got that as the vehicle seems to spool up a bit quicker and way better throttle response. That made the product worth it. I was hoping to get some extra gas mileage out of it as I have in other vehicles. I can't see much difference in it at this point and have tried to drive the same with roughly the same routes. The noise is not noticeable at normal cruising speeds and just a little louder otherwise. Overall happy.
