JBA 96-04 Ford 4.6L/5.4L 4V DOHC Oval Port Header Gasket - Pair

These JBA header gaskets are made from a thick, specially formulated material designed to handle the high pressures and temperatures found in performance exhaust systems. They are specifically made to match the port shape of JBA headers, ensuring a clean seal and preventing exhaust leaks. This pair is built to handle exhaust pressures up to 3700 psig and can withstand temperatures up to 1100 degrees Fahrenheit, making them a solid choice for your 4.6L or 5.4L 4V DOHC Ford engine from 1996 to 2004.

Getting a good seal on your exhaust headers is crucial for performance and preventing those annoying leaks. These gaskets are designed for an exact port match with JBA headers, which means you won't have to worry about trimming or forcing them into place. The extra thickness of the gasket material helps to conform to any minor imperfections on the header flange or cylinder head surface, creating a more reliable seal under demanding conditions.
