00-04 Mitsubishi Eclipse 4CYL Exhaust Header Gasket - Aluminum
Aluminum header gasket built for 4-cylinder Eclipse engines, designed to seal and withstand manifold heat cycles. Engineered for a tight seal at the cylinder head-to-header junction without premature failure. Aluminum construction handles repeated thermal expansion and contraction.
Do I need to clean the gasket seating surfaces before installation?
Yes. Remove any carbon buildup or old gasket material from both the cylinder head and header flange with a gasket scraper or wire brush. A clean, flat surface ensures proper sealing.
Will this gasket work if my header has been welded or modified?
This gasket is engineered for factory-spec mounting surfaces. If your header has been welded or altered, test-fit first to confirm the gasket sits flush against both surfaces without gaps or compression.
What torque spec should I use when bolting the header back down?
Refer to your vehicle service manual for the correct fastener torque sequence. Over-tightening aluminum gaskets can cause creep; follow OEM spec exactly.
