arrow To find your Prechambers choose your Year, Make and Model first.


Prechambers, which are also known as pre-combustion chambers, are components of your vehicle's diesel engine. The prechamber improves the engine's combustion process by burning a small amount of fuel before it is delivered to the main combustion chamber. It is a spherical component that is mounted in the cylinder head.

During the compression stroke, the prechamber takes in a small amount of compressed air from the main chamber, when the fuel is injected into it. The air-fuel mixture is burnt and the atomized fuel is sprayed through small holes into the main chamber. If you are looking to replace a bad or damaged prechamber, you have come to the right place. At Buy Auto Parts we stock a wide variety of prechambers for every car make and model.

We have genuine OEM replacements and premium aftermarket parts. All our car parts are thoroughly tested and come with a warranty.
