its not going into the pipe it is going into the rubber piece that is right off the throttle body and before the pipe, i am making sure that won't change with the retrofit kit. if it won't i can mount it now. it has to be mounted after the maf sensor and before the throttle body and if it is in that rubber piece will be a direct spray into the throttle body and will be after sensor before throttle body, and easy to swap out later if i wanted to change intake or go without the spray.
