Halltech 4.5" X 4.150" WP102 Throttle Body Connector Hose Corvette for Nick Williams Performance

Nick Williams Performance 4.5" X 4.150" X 2.4" WP 102 Throttle Body Connector Hose is our proprietary 4 ply black silicone hose made to couple the Halltech Super Bee to the Nick Williams 102 Throttle Body. This hose is 4.5" at the large end for our SB, and 4.15" at the small end to fit tightly over the Williams Throttle Body. If you anticipate putting the larger throttle body on your motor at a later date, or have already, you will need this hose to make it all work. Please indicate in if you require the PCV nipple hole.
