The Cometic MLS head gasket for Nissan SR20DE/DET GTir RNN14 with an 86.5mm bore and AWD fitment is a multi-layer steel replacement designed to meet demanding sealing conditions. MLS construction uses embossed AMP-coated outer layers and an uncoated stainless steel shim center to conform to surfaces, require less clamp load, reduce bore distortion, and distribute sealing load across the gasket area.
