Multiple grades of steel ensure optimal sealing at the surface and combustion chamber when torqued down. A Nitrile rubberized coating on the top and bottom layers accommodates rougher RA surface finishes—up to 50 microinch—ensuring a better seal in non-critical areas. To further enhance performance, a folded stopper layer at the gasket’s edge delivers superior combustion chamber sealing, reducing the risk of head gasket failure under high cylinder pressures common in built engines.\u003c\/p\u003e\n\u003cp\u003eAfter consulting with engine builders and tuners, GrimmSpeed recognized the need for multiple gasket thickness options. As a result, this gasket is 0.78mm thicknesses to fine-tune compression and fitment. The slightly oversized bore diameters also support up to a 0.5mm overbore.\u003c\/p\u003e\n\u003cp\u003eDesigned for compatibility with both the FA20F DIT (Subaru WRX) and FA20D (Subaru BRZ, Scion FRS, Toyota GT86), these gaskets perform equally well in naturally aspirated and forced induction applications.\u003c\/p\u003e\n\u003cp\u003eWith the FA20 Head Gasket Sets, GrimmSpeed continues its legacy of delivering premium, reliable components trusted by enthusiasts and professionals alike.\u003c\/p\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eSold as a Set\/Pair -L and R side specific\u003c\/li\u003e\n\u003cli\u003eDie Cut Multi-Layer [Stainless] Steel (MLS) Construction- Provides smooth edge finish and consistency from batch to batch, ±0.001” manufacturing tolerance\u003c\/li\u003e\n\u003cli\u003eFolded Stopper Layer to Better Seal the Combustion Chamber\u003c\/li\u003e\n\u003cli\u003e.25micron Nitrile Rubber Layer Coating - Reduces chances of leaking on imperfectly smooth mating surfaces over non-coated gasket.\u003c\/li\u003e\n\u003cli\u003eCompatible with both FA20F DIT (WRX) and FA20D (BRZ, FRS, 86)\u003c\/li\u003e\n\u003cli\u003eAccommodates up to 86.5mm bore\u003c\/li\u003e\n\u003cli\u003e0.78mm thickness (after crushing)\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Grimmspeed","offers":[{"title":"Default Title","offer_id":48062581801178,"sku":"GRM124006","price":199.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0828\/8623\/0234\/files\/022009-022010FA201.05_05_1200px__22981.1744727607.1280.1280.jpg?v=1781530804","url":"https:\/\/www.iagperformance.com\/products\/grimmspeed-head-gasket-set-78mm-subaru-fa20","provider":"IAG Performance","version":"1.0","type":"link"}
