i wouldnt bother, you wouldn't notice much at all. I know these are about 10 times more expensive but get a twin throttlebody setup, then there will be difference.
do u know if u can replace a v6 throttle body with on from a v8? i got a v8 one sitting here but all the sensors etc are in different spots so im not sure if it will bolt on or not? any1 done this b4 or know if its possible?
