LS MLS Exhaust Manifold Header Gasket Pair and Bolts For LS1 4.8L 5.3L 5.7L 6.0L 6.2L 12617944 - Lizixny 551696

• The exhaust manifold gasket can effectively collect and extract high-temperature exhaust gas from the combustion of each cylinder of the engine, and output the exhaust gas to the lower processing device in a reasonable way, so that the lower processing device can post-treat the exhaust gas to meet the requirements of emission regulations. How can our Exhaust Manifold Head Gasket achieve corresponding durability and fatigue requirements through reasonable structural design and material selection, so that the exhaust manifold does not crack Our Exhaust Manifold Head Gasket can avoid the problem of exhaust interference caused by different combustion ignition sequences of each cylinder in the engine, and the wavy and curved structure of the first splitter plate makes it difficult for exhaust gas to generate vortices when passing through the exhaust main pipe, which is beneficial for compensating for the cracking and leakage problem caused by high exhaust gas temperature.
