Exhaust Gas Recirculation (EGR) Tubes direct exhaust gases from the exhaust manifold through the EGR system. The tubes ultimately recirculate the gases back into the combustion chambers to be burned again. To provide coverage for this key category, Standard® offers a line of more than 65 EGR Tubes. Each one is a direct-fit OE replacement that's manufactured using high-quality materials to ensure proper fit, form, and function.
