The IAG Performance Cooper ring head gasket is manufactured from an asbestos-free composite raw material and features silicone based beading applied to critical areas to improve sealing around all water and oil passages. What sets this gasket apart from others is the separate stainless steel rings surrounding the bore holes. The rings assure maximum sealing for a turbocharged engine and the block and head do not require any special machining. The IAG Cooper ring gaskets are designed for high horsepower, high boost applications. The gaskets are not recommended for blocks or heads that are o-ringed. This gasket set is sold as one pair. Features: Composite Material Stainless Steel Ring (AISI304) Silicone Beading 100mm Bore .051" Thickness Intended for High Horsepower, High Boost applications.
