2015-2021 Subaru WRX

The Cometic MLX Head Gasket C4954‑032 is engineered for high performance and reliability in the Subaru FA20 (VA‑series WRX) engines. Built with a multi‑layer steel (MLX) construction, this head gasket provides excellent sealing under extreme temperatures and pressures, with a built‑in “stopper” layer to maintain integrity without distortion.

Key Features & Benefits

  • MLX (Multi‑Layer Stopper) design — Combines the strength of MLS-style gaskets with an integrated combustion sealing stopper layer

  • 0.032″ compressed thickness — Precise tolerance for reliable sealing and consistent performance

  • Three layers of steel/fiber laminate material — Helps seal irregular surfaces and deal with thermal expansion

  • No sealants or re‑torque needed — Simplifies installation and reduces error risk

  • High temperature performance — Withstands race-level conditions, ideal for tuned or high-stress builds

  • Left head side (driver’s side in many layouts) — Be sure to match side (you’ll also need the matching right side gasket, e.g., C4955‑032 variant)

Installation & Usage Notes

  • Ensure both head and block deck surfaces are clean, true, and within spec before installation.

  • Use correct torque sequence and final torque specs prescribed for your engine.

  • Since this gasket is “no re‑torque / no sealant,” don’t add extra coatings or adhesives unless recommended by your machine shop.

  • Always match left/right sides properly — the orientation matters.

  • If running high boost or aggressive tuning, inspect after initial use to confirm proper sealing.
