Sounds like my SUV developed Asthma!
I am very disappointed in this product. No increase in MPG and no difference in throttle response. It made my SUV sound like it had developed asthma with the obnoxious whistling and wheezing! Everyone that got in my SUV asked what is that terrible noise! I was also disappointed to learn that Autoanything would not take it back since it was "used" once I installed it. save your money and stay way from this!
