Actually that is not necessary in our cars since the tb is open all the time. we dont need the plate at all in reality. but for every other car that isnt a n52/n55, yes that would have to be done |
The butterfly serves as a backup in case you have a valvetronics motor failure. I forgot to connect the valvetronic motor wiring after changing my vcg and didn't notice it for a week.
