Product Description:

Looking to build your supercharged 3.0T engine to the next level? The 034Motorsport MLS (Multi-Layer Steel) Head Gasket Set is an optimal upgrade over the factory head gasket. The 034Motorsport MLS Head Gasket Set utilizes 4 layers of steel that ensure a strong seal between the two cylinder heads, and is designed for high boost and high-stress applications, perfectly suited for B8 3.0T Stage 2 and beyond.

MLX Construction Benefits:

The MLX design, a Cometic development, utilizes an extra “stopper” fold-over layer which serves as an extra layer in the gasket. This extra layer provides a torque limiting surface that prevents the combustion seal from yielding, and contains high-temperature polymers and embossments that provides a seal to protect the head and block surface against oil and coolant. As a result, the 034Motorsport MLS Head Gasket Set allows for better combustion sealing, lower bore distortion and improved reliability. Unlike copper head gaskets, the MLX construction allows for the strongest seal around the combustion chamber while offering superior fluid sealing to ensure that this gasket set won’t cause reliability problems once installed. Compared to the OEM head gaskets, these head gaskets offer superior combustion chamber sealing for increased engine outputs and higher combustion pressures.
