Installed it with a K&N 77 Cold Air Intake and a Jet Power-Flow Mass Air Sensor and saw incredible jumps in power and gas efficiency. Will recomend to everyone, especially with todays gas prices.

At first I wasn't sure if it really was working cause I couldn't really see big changes but after about a month I noticed the mpg gains. The power increase was quite amazing too. I feel this is a great product and as they say" you get what you pay for ". Already thinking about upgrading to the IQ.

Fast delivery,easy install,and it doesn't make car faster but it does make it quicker because there's no lag in the pedal so it's much quicker off the line..with my other add ons this car isnt your typical 3 series..a definite buy..
