Replacement Supercharger Filler Neck A++
Great product. Works great and is perfect for replacing your stock Filler Neck. Use the cap that comes with this item. It is self venting, and helps reduce any air trapped within the coolant lines.

Works great even on other cars
Used this filler kit on a foxbody mustang that has 03 cobra terminator dohc sc swap. The heat exchanger i used had the inlet and outlet on opposite sides (the stock one is on the same side) and it kept losing it's prime due to the pump location and hose routing. The drivers side was fine but air kept getting trapped near the pump on the passenger side, installed the filler inline going back to the intercooler (above the belt) and instantly air the are was let out. It was a well spent 40 bucks.



Easy fillings
Easy to install. Made filling my intercooler coolant system so much easier
