GrimmSpeed has set the standard for quality when it comes to aftermarket replacement gaskets so it's only natural that we should offer our fans\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eThe Most important gaskets their car will ever need:\u003c\/strong\u003e Introducing The GrimmSpeed FA20 Head Gasket Sets! Feature-packed, these gaskets are a perfect fit for any engine build, from basic refresh to a high horsepower track monster. The GrimmSpeed Head Gaskets feature a multi-layer steel (MLS) construction, in which multiple grades are used to provide optimal surface and combustion chamber sealing as they are torqued down.\u003c\/p\u003e\n\u003cp\u003eThe top and bottom Layers feature a Nitrile Rubberized Coating that helps accommodate a rougher RA surface finish of up to 50microinch. This acts to better Seal the non-critical areas of the gasket. В In addition, the gasket edge includes a folded stopper layer that allows for optimal sealing for the combustion chamber.\u003c\/p\u003e\n\u003cp\u003eThis is done to help reduce the chances of combustion gasses causing head gasket failures under extremely high cylinder pressures that built engines can experience. After talking to numerous engine builders\/tuners it was clear that creating a variety of gasket thicknesses was key for pairing them with the right build.\u003c\/p\u003e\n\u003cp\u003eWith that in mind, we've made the gaskets available in multiple thicknesses (.78, 1.05, 1.45mm) to help fine tune each individual build. In addition, the slightly oversized bore diameters will allow for up to 0.5mm overbore.\u003c\/p\u003e\n\u003cp\u003eThe FA gaskets were Designed to be compatible in both FA20A (WRX) and FA20B (BRZ, FRS, 86).\u003c\/p\u003e\n\u003cp\u003eMeaning that it will be just as much at home in a lower power NA build as it will be in a high power boosted application. We've outdone ourselves this time, The GrimmSpeed Head Gaskets carry on the legacy of quality that you've come to know from our other extremely popular gaskets.\u003c\/p\u003e\n\u003cp\u003e\u003cb\u003eQuick Specs\u003c\/b\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eSold as a Set\/Pair\u003c\/li\u003e\n\u003cli\u003eL and R side specific\u003c\/li\u003e\n\u003cli\u003eDie Cut Multi-Layer Stainless Steel (MLS) construction\u003c\/li\u003e\n\u003cli\u003eProvides 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 .25micron Nitrile Rubber Layer Coating\u003c\/li\u003e\n\u003cli\u003eReduces chances of leaking on imperfectly smooth mating surfaces Over non-coated gasket.\u003c\/li\u003e\n\u003cli\u003eCompatible with both FA20A (WRX) and FA20B (BRZ, FRS, 86)\u003c\/li\u003e\n\u003cli\u003eAccommodates up to 86. 5mm bore 0. 78mm, 1. 05mm, 1. 45mm thickness (after crushing)\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003eTesting GrimmSpeed High Performance Head Gaskets are Designed to optimize combustion chamber sealing. This is done by using a unique gasket Design feature which sets us apart from the competition.\u003c\/p\u003e\n\u003cp\u003eBy strategically undercutting the middle layer of the gasket near the combustion chamber, we can control the crushing of outer Layers, which in turn creates a perfect Seal around the combustion chamber. We can visually demonstrate this feature by using pressure sensitive film and compressing the gasket in a manner which mimics the tightening of a head against the block.\u003c\/p\u003e\n\u003cp\u003eThe film changes colors from white to pink to Redas pressure is applied to deNote areas of high and low pressure application. This information will then allow for easy visual verification of effectiveness in sealing of a gasket against a surface.\u003c\/p\u003e\n\u003cp\u003eAs seen in the results, the combustion chambers are sealed evenly and equally around the circumference of the cylinder by the deep part circles. This visual representation is showing that combustion gasses are going to be held in the chamber and directed towards pushing the piston instead of escaping.\u003c\/p\u003e\n\u003cp\u003eFailure of a gasket to Seal with even pressure around the circumference of the cylinder would be detrimental for performance and reliability of a gasket and would Most certainly result in failure. When combining the perfect sealing, Nitrile Coating and other features of the gaskets, we are able to ensure that your engine build is ready for anything that you throw at it.\u003c\/p\u003e\n\u003cp\u003eFrom basic engine refreshes to full blown race builds, The Mark of Innovation from GrimmSpeed keeps you in control under pressure!\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003e Fitment\u003c\/strong\u003e 15-20 WRX FA20A 13-20 BRZ\/FRS\/86 FA20B\u003c\/p\u003e\n\u003ch2\u003eAdditional Description\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eLimited Lifetime\u003c\/li\u003e\n\u003cli\u003eCALIFORNIA WARNING: Cancer and Reproductive Harm - www.P65Warnings.ca.gov\u003c\/li\u003e\n\u003cli\u003e1.45mm\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"GrimmSpeed","offers":[{"title":"Default Title","offer_id":44831374704838,"sku":"GRM124008","price":182.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0081\/0804\/8420\/files\/124008-JBCB_d51c90a0-af13-43bb-9667-7b6303b8b49b.jpg?v=1755871418","url":"https:\/\/www.graveyardperformance.com\/products\/grimmspeed-head-gasket-set-1-45mm-for-subaru-toyota-15-21-wrx-13-21-brz-frs-86-fa20a-b","provider":"Graveyard Performance","version":"1.0","type":"link"}
