EGR Tube Gasket 99-13 Chevy LS

The EGR tube gasket for 99-13 Chevy LS engines is a critical sealing component that prevents exhaust gas recirculation system leaks at the junction between the EGR tube and cylinder head. As an LS platform builder or mechanic performing engine work, you'll encounter this gasket during routine maintenance, head gasket jobs, or when diagnosing coolant leaks around the EGR passage. MAHLE ORIGINAL/CLEVITE manufactured this component to OEM specifications, ensuring reliable performance across naturally aspirated and boosted LS applications from early Gen III engines through the Gen IV platform.

This gasket uses advanced elastomer and composite materials designed to withstand continuous thermal cycling and exhaust gas exposure without degradation. The precise geometry seats flat against both the EGR tube and cylinder head surface, creating a compression seal that eliminates bypass leakage that would otherwise allow unburned exhaust to enter the cooling system or contaminate engine oil. Unlike cheap aftermarket alternatives, MAHLE ORIGINAL delivers the exact thickness and material composition needed to maintain proper EGR flow control and prevent the coolant system contamination that commonly occurs with failed or undersized gaskets.

Any LS swap, engine rebuild, or head removal on 1999–2013 Chevy LS-equipped vehicles—whether truck, Camaro, Corvette, or CTS-V—requires a fresh EGR tube gasket to prevent coolant system contamination and exhaust leakage. Installation is straightforward: remove the EGR tube at the cylinder head, discard the old gasket, clean the mating surfaces with brake cleaner, position this gasket, and torque the tube fitting to spec. This small part is essential insurance against costly coolant leaks and rough idle conditions that plague builds using worn or reused gaskets.
