GrimmSpeed Turbo Exhaust Manifold-to-Head Gasket – Subaru EJ / FA / FB | Pair | 020001

Sold as a pair (LH + RH) — both manifold gaskets for one complete replacement. For turbocharged Subaru EJ, FA, and FB engines. OEM Subaru reference: 14038AA000.

GrimmSpeed 020001 OEM-specification turbo exhaust manifold-to-head gasket for Subaru EJ, FA, and FB turbocharged boxer engines. Sold as a pair covering both cylinder banks. Direct replacement for Subaru OEM part 14038AA000. Seals the exhaust manifold against the cylinder head exhaust port face — a high-heat, high-pressure interface that is typically inspected or replaced during turbo removal, manifold service, or engine rebuild. 0.3 lbs. Ships fast across Canada and the US.

When to Replace Exhaust Manifold Gaskets

The turbo exhaust manifold-to-head gasket seals the exhaust manifold flange against the cylinder head. Failure symptoms include an exhaust tick or blowing noise that is most pronounced when the engine is cold and may reduce or disappear as the engine warms and the manifold expands against the head. A failed manifold gasket can also introduce exhaust gases and heat into the engine bay near the turbo and intake components, affect turbo spool consistency, and cause exhaust odour in the cabin. Common replacement scenarios on Subaru turbocharged engines include: manifold gasket failure (exhaust tick), turbo removal and reinstallation (best practice to replace at this time), head removal, and full engine rebuild.

EJ / FA / FB Turbocharged Fitment

The GrimmSpeed 020001 gasket covers Subaru’s turbocharged EJ, FA, and FB boxer engine families:

• EJ series (EJ20, EJ25 — turbocharged variants): EJ205 (WRX 2002–2005, Forester XT), EJ207 (JDM STI), EJ255 (Legacy GT, Forester XT, Outback XT), EJ257 (WRX STI 2004+). The EJ is the most common turbocharged Subaru application and the primary fitment for this gasket.
• FA20DIT: Used in the 2015–2021 Subaru WRX (not STI). Different engine architecture from EJ but shares the same OEM manifold gasket specification per the 14038AA000 cross-reference.
• FB turbocharged variants: Confirm your specific FB application is turbocharged and uses this gasket specification. Naturally aspirated FB engines use a different exhaust manifold configuration.

Confirm your specific engine code and variant against GrimmSpeed’s fitment data or the OEM 14038AA000 cross-reference before ordering.
