I have a JHA kit and when I first installed I did not use the X & Y tubes. What I noticed on NSR-WORLD site is that one end of the X is left open to the air. Does it matter if it is attached to the line going to the air box ? Or should that line just be eliminated ? I have installed them, but attached the X tube to the line going to the airbox T line.
Can anyone describe how these work and what they do and when ?
