Having installed the greater majority of bolt-ons available for my vehicle, it is fair to say without a shadow of a doubt the IPD Intake Plenum/75mm Throttle Body thus far has been the most rewarding purchase of them all. Coupled with my setup, the intake/tb upgrade is my most recent modification and my most favorite. There is a discernible difference and as I told many others via private message, I have never been thrown back into the seat of my car prior to the installation of any single mod nor collectively! I have well over 2,000 with the modifcation and I find myself looking for reasons to drive my vehicle more, when it already is my daily driver. My only complaint is Road Sport Supply not supplying me with a get out of jail free card due to the fact I was arrested the day of flashing my vehicle with FVD Brombacher's software for wreckless driving!

/e I have been hesitant to make a post since the successful installation of the intake/tb plenum due to all the reservations held by many, and having not putting my vehicle on a dynograph to supplement these gains.
