When it comes to managing fluid lines in your race car, using a pass-through can be a game-changer. Not only does it give you the ability to easily disconnect fluid lines from either side of a firewall or panel, but it also eliminates the need for running hoses through grommets, which can wear down over time and become a safety hazard.
The UPR Billet Single or Double Firewall Pass-Through is a great way to cleanly run your intercooler, crankcase breather, or any other fluid lines through your firewall or other panels without restricting flow.
The pass-through uses 20an orb threads on both sides and comes black anodized for a clean, durable finish. UPR offers a wide variety of high-flow adapter fittings for nearly any application, and stainless steel mounting hardware is included.
The single pass through mounting flange measures 2-7/16 x 2-7/16, while the double pass through mounting flange measures 4-3/4 x 2-7/16.
