IAG Fire-Lock Head Gaskets (1 Pair w/ Fire-Lock Rings) For 14mm Head Studs Only, 2002-2005 WRX

The IAG Performance Fire-Lock head gasket solution was created after years of research and development testing to prevent head gasket failure on high horsepower and high boost Subaru EJ Series engines. This solution is loosely derived from diesel technology where a counter bore step is machined around each cylinder bore allowing specially sized fire rings to drop into the machined area and head gasket bores. The shims are designed to create a compression seal once the heads are installed and torqued into place. IAG fire rings are manufactured to a very strict tolerance from a proprietary alloy and are then put through a heat treatment process. The gaskets are manufactured from an asbestos-free composite raw material and feature a silicone based beading applied to critical areas to improve sealing around all water and oil passages. The combination of the alloy compression shims and gaskets assure maximum sealing for a Subaru EJ20 turbocharged engine.
