(c)gasket, Cyln He (nas)

Using OE gaskets and seals will help protect the engine and carburettor/s against unwanted leaks of oil, air, or water. Whatever the gasket's job; it will do it better if it is a high-quality OE gasket. This cylinder-head gasket is one of the most important gaskets in the engine.
As with most things in life you get what you pay for and using cheap none-Japanese made gaskets and seals could end up costing an awful lot more if they fail to do their job.

OE parts that are up to the job.

Using cheaper parts could be very costly!
