What does MLS stand for in Cometic MLS gaskets?

MLS stands for Multi-Layer Steel. This construction uses multiple layers of steel to create a strong, durable gasket that can withstand high pressures and temperatures.

Do I need to use any sealant with these gaskets?

No, sealants are not required with these Cometic MLS exhaust gaskets. They are designed to create a reliable seal on their own when properly torqued.

Nissan Pulsar NX 1988-1989

Product Details

If you're rebuilding the top end of your 1988 or 1989 Nissan Pulsar NX with the CA18DET engine, getting the exhaust manifold sealed up right is crucial. These Cometic Multi-Layer Steel (MLS) exhaust gaskets are built to handle the high pressures and temperatures that come with that engine. They're designed to maintain their torque setting and resist corrosion, so you won't have to worry about them burning through or getting pushed out of place, even with different materials used for the cylinder head and exhaust manifold.

The multi-layer steel construction means these gaskets are very durable and won't require any additional sealants to get a good seal. This makes installation straightforward, as you just need to ensure the mating surfaces are clean and then torque the manifold down according to spec. You get four gaskets in this kit, which is exactly what you need for the CA18DET engine.
