What does the '.030in' mean on this head gasket?

The '.030in' indicates that this is an oversize gasket. It's designed for engines where the cylinder head or block deck has been machined down by 0.030 inches. Using an oversize gasket on a standard deck height can cause issues, so it's important to confirm your engine's machining specs.

What is a Multi-Layer Steel (MLS) gasket?

MLS gaskets are made from multiple layers of steel, often with a special coating. This construction allows them to be very strong and conform to engine surfaces, providing excellent sealing for high-pressure and high-temperature applications like modern engines.

Does this gasket come with any other parts?

This product is for the cylinder head gasket only. It is recommended to replace head bolts when installing a new head gasket, as they can stretch during installation and may not provide proper clamping force if reused. Check the manufacturer's instructions for specific recommendations.

About this part

Product Details

Cometic Gasket is known for making gaskets right here in the USA, using American-made materials. If you're working on the QR25DE engine in your 2005-2012 Nissan Frontier, this Multi-Layer Steel (MLS) head gasket is built to handle the demands of modern engines, which often run higher cylinder pressures and temperatures. It's a well-built component designed to keep your engine sealed up tight.

This particular gasket is a .030 inch oversize, meaning it's meant for engines that have been machined or honed to that specific dimension. The 90mm bore size is matched to the QR25DE engine. MLS gaskets are popular because they offer good sealing and can rebound to resist corrosion, helping to ensure a long service life in your Frontier's engine.
