GrimmSpeed Exhaust Manifold to Head Gasket - Subaru EJ/FA/FB Turbo
GrimmSpeed set out to fix a common weak point in Subaru turbo engines: exhaust manifold gaskets that leak even when they're marketed as multi-layer. This pair of gaskets uses a genuine 304 stainless steel fire-ring construction, built thicker than the factory piece for a more reliable seal under heat and boost.
This listing covers Subaru vehicles fitted with a turbocharged EJ series engine, plus FA and FB series turbo and naturally aspirated engines. GrimmSpeed supplies these as a matched pair, cross-referencing to Subaru part number 14038AA000.
Key Features
- Sold as a pair
- 22% thicker than OEM gaskets for improved sealing
- All stainless steel construction
- 304 stainless steel fire-ring
- Cross-references to Subaru OEM part number 14038AA000
