Product Details
This Cometic Multi-Layer Steel (MLS) head gasket is what you get when you need a solid seal for your 4A-GE or 4A-GEZ engine. It's built with multiple layers of stainless steel, giving it the strength to handle the demands of higher output engines. The outer layers are coated with Viton, a heat-resistant rubber material that can handle tough sealing environments and works well with aluminum or cast iron blocks. This gasket is designed to provide maximum sealing performance without needing any extra sealants.
The multi-layer steel construction means this gasket is strong and can rebound, helping it resist corrosion. The Viton coating on both sides is good up to 482 degrees Fahrenheit, making it suitable for engines that run hot. The center layer is stainless steel and can be varied in thickness; this particular gasket has a compressed thickness of 0.036 inches and an 83mm bore, making it a good fit for the 16-valve 4A-GE/4A-GEZ engines found in specific Toyota models.
