It has a 101mm round bore and comes in a choice of compressed thicknesses, so you can match the stock deck height or set the compression ratio on a rebuilt engine.\u003c\/p\u003e\u003cp\u003eCometic's MLX (Multi-Layer Xtreme) gasket adds a fold-over stopper layer around each bore. The stopper acts as a torque-limiting surface that stops the combustion seal from yielding, which suits high-boost engines with high cylinder pressure. Coated, embossed layers seal the coolant and oil passages.\u003c\/p\u003e\u003ch3\u003eOptions\u003c\/h3\u003e\u003cp\u003eCompressed thickness: 0.81mm (.032\"), 1.12mm (.044\"), 1.52mm (.060\"). Thicker gaskets lower compression; match the thickness to your engine builder's spec.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eNote:\u003c\/strong\u003e Sold individually – an EJ engine needs two, one for each head. Cometic lists a different gasket (C14181) for 2018–2021 EJ257 engines, and C4622 for EJ253\/EJ255 with the improved-cooling heads. Installation by a professional is recommended.\u003c\/p\u003e\u003ch3\u003eFeatures\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eCometic MLX multi-layer stainless steel construction\u003c\/li\u003e\n\u003cli\u003eFold-over stopper layer around each bore stops the combustion seal yielding under high boost\u003c\/li\u003e\n\u003cli\u003e101mm round bore\u003c\/li\u003e\n\u003cli\u003eChoice of compressed thickness to suit stock or built engines\u003c\/li\u003e\n\u003cli\u003eInstalled dry – no sealant needed\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eKit Contents\u003c\/h3\u003e\u003cul\u003e\u003cli\u003e1 x Cometic MLX cylinder head gasket\u003c\/li\u003e\u003c\/ul\u003e\u003cp\u003eNeed help confirming fitment?
