Inspired by diesel technology, this system incorporates a counterbore step machined around each cylinder bore, allowing specially sized fire rings to seat precisely into the machined areas and head gasket bores. These fire rings are engineered to create a reliable compression seal once the cylinder heads are installed and torqued.\u003c\/p\u003e\n\u003cp data-is-only-node=\"\" data-is-last-node=\"\" data-end=\"1099\" data-start=\"526\"\u003eIAG fire rings are manufactured from a proprietary alloy to extremely strict tolerances and undergo a heat treatment process to maximize strength and durability. The gaskets themselves are made from an asbestos-free composite material and feature silicone-based beading applied to critical areas to improve sealing around all water and oil passages. The combination of the precision alloy fire rings and the high-quality gaskets ensures maximum sealing performance for turbocharged Subaru EJ20 engines, providing peace of mind under extreme boost and high-power conditions.\u003c\/p\u003e\n\u003cp data-is-only-node=\"\" data-is-last-node=\"\" data-end=\"1099\" data-start=\"526\"\u003e\u003cbr\u003e\u003cstrong\u003eFeatures:\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eComposite Material\u003c\/li\u003e\n\u003cli\u003eIAG-Spec Alloy Ring\u003c\/li\u003e\n\u003cli\u003eSpecifically designed for 14mm Head Studs\u003c\/li\u003e\n\u003cli\u003eSilicone Beading\u003c\/li\u003e\n\u003cli\u003e93.50mm Bore\u003c\/li\u003e\n\u003cli\u003e.051\" Thickness\u003c\/li\u003e\n\u003cli\u003eIntended for High Horsepower, High Boost applications\u003c\/li\u003e\n\u003cli\u003eIAG ARP 14mm Head Studs Required\u003cbr\u003e\n\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cstrong\u003eNotes:\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eThe IAG Fire-Lock gaskets require machine work for installation and are recommended for use with 14mm head stud hardware.\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003eThe gaskets are sold in pairs with four Fire-Lock rings.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cstrong\u003eInstall Notes:\u003c\/strong\u003e\u003c\/p\u003e\n\u003col\u003e\n\u003cli\u003eIf a block or cylinder head was previously o-ringed the groove must be filled and resurfaced before using this type of gasket.\u003c\/li\u003e\n\u003cli\u003eThese gaskets require IAG ARP 14mm head studs to achieve the required torque necessary for proper installation.\u003c\/li\u003e\n\u003cli\u003eDue to the required torque, any block that was previously honed will need to go to the next size overbore.\u003c\/li\u003e\n\u003cli\u003e Future servicing will require cylinder head resurfacing due to an imprint left from the Fire-lock rings.\u003c\/li\u003e\n\u003c\/ol\u003e","brand":"IAG Performance","offers":[{"title":"Default Title","offer_id":44976965255343,"sku":"IAG-ENG-1745","price":329.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0587\/3598\/4815\/files\/iag-performance-fire-lock-head-gasket-pair-ej20-935mm-bore-051-thickness-w-14mm-head-studs-2002-2005-wrx-iag-eng-1745-428153.png?v=1742180823","url":"https:\/\/subimods.com\/products\/iag-performance-fire-lock-head-gasket-pair-ej20-93-5mm-bore-051-thickness-w-14mm-head-studs-2002-2005-wrx","provider":"Subimods.com","version":"1.0","type":"link"}
