One of my customers contacted me yesterday and informed me that the lower cold side charge pipe does not clear the transmission on his automatic. I'm working with him to redesign this part to work with the auto. I'm not sure if I'll offer two versions for 6spd and auto or one that fits both. Currently the "cold" charge piping is almost a straight shot to the throttle body. In order to clear the auto, the pipe will need to have at least two bends added.
