installed on a 2003 base model 350z MT, with many supporting mods .. headers, test pipes, exhaust, plenum spacer ect... (NO TUNE). Install was pretty easy and straightforward , you will have to re use the stock metal throttle body gasket as it only comes with one gasket for the spacer to throttle body. I was hesitant on buying one since ive seen tons of reviews and forums on how these made the car run awful and idle terrible but my Z fired right up no check engine lights or rough idle. If anything the car idles a lot better now and doesn't idle hunt around 500-750 like it did before. As far as power gains the car does feel more responsive and smoother, probably needs a good tune to actually take full advantage of it. All in all though great product and just follow the directions and you should defiantly enjoy it. **IMPORTANT** DO NOT touch/push back the throttle body butterfly valve when you get it or put it in, I know its tempting but they are calibrated from the factory and doing so could throw it out of calibration and that's how I think a lot of the forum guys got the rough idle and check engine lights.
