Fits select 2012-2019 Audi A3, A4, A5, Q3, Q5, TT, and TTS models (2.0L).

The Cometic MLS (Multi-Layer Steel) head gasket is engineered to provide a superior seal for high-performance and OE-replacement 2.0L Audi engines. Constructed from three to five layers of high-grade stainless steel, this gasket offers exceptional strength, corrosion resistance, and the ability to rebound under varying load conditions. The outer layers are embossed and coated on both sides with a Viton rubber material, designed to withstand heat up to 250°C (482°F) and accommodate various surface finishes.

By utilizing an embossed design, the Cometic C4978-040 requires less clamp load than traditional gaskets, resulting in significantly less cylinder bore distortion. This ensures uniform load distribution across the sealing area, maintaining engine integrity in harsh environments.
