Product Details
If you're rebuilding the top end of your 2004-2007 Saturn Ion with the 2.0L DOHC Turbo Ecotec engine, this Multi-Layer Steel (MLS) head gasket from Cometic is a solid choice. It's designed to handle the demands of high-output engines, ensuring a strong seal between your cylinder head and engine block.
This gasket is built with multiple layers of stainless steel for increased strength and corrosion resistance. The outer layers are coated with Viton, a heat-resistant rubber material that can handle temperatures up to 482°F (250°C), making it suitable for both aluminum-to-aluminum and aluminum-to-cast iron block configurations. The compressed operating thickness is precisely 0.040 inches, with an 87mm bore to match your engine. Because it's an MLS design, it doesn't require any additional sealants, simplifying installation.
