Overtake Exhaust Manifold to Head Gasket Set 04-09 Outback H6 / 08-19 Legacy H6 / 06-14 Tribeca | Multi-Layer Steel | Exhaust Gasket Replacement
Overview
The Overtake Exhaust Manifold to Head Gasket Set is a direct OEM replacement designed specifically for Subaru H6 engines, including the EZ30 and EZ36 found in the 2004-2009 Outback, 2008-2019 Legacy, and 2006-2014 Tribeca models. This gasket seals the critical joint between the exhaust manifold and cylinder head, an area exposed to extreme heat and pressure. Subaru discontinued the original OEM gasket (part number 44011AG040), leaving a gap filled by inferior aftermarket options that often fail prematurely. The Overtake gasket set addresses this issue with a robust, multi-layer steel construction and a stainless steel fire ring to ensure a reliable, leak-free seal.
Engineered with durability and longevity in mind, this gasket set is 22% thicker than the original OEM part, providing enhanced clamping force retention and resistance to heat cycling. Unlike many budget aftermarket gaskets that use thin, stamped, and partially non-stainless materials prone to the notorious waffle-gasket blowout, the Overtake gasket maintains integrity under the demanding conditions of Subaru’s H6 exhaust system. This attention to material quality and design makes it the ideal choice for both stock and tuned applications, including H6 engine swaps where reliability is paramount.
For Subaru owners, maintaining a proper seal at the exhaust manifold is essential to prevent leaks that can affect performance, emissions, and engine bay temperatures. The Overtake gasket set restores the factory-level sealing capability with improved materials and thickness, ensuring your Subaru H6 runs cleanly and efficiently. Sold as a pair, it allows for a comprehensive service of both cylinder heads in one installation, making it a practical and essential upgrade for maintaining or restoring your Subaru’s exhaust integrity.
