Porsche Engine Cylinder Head Bolt Kit - Genuine Porsche 9A110419102KT

Product Information

An engine cylinder head bolt set is a collection of high-strength fasteners used to secure the cylinder head to the engine block. These bolts must withstand extreme pressure and temperature changes while maintaining a tight seal between the head gasket, cylinder head, and block. Proper installation and torquing of the head bolts are critical for preventing leaks, maintaining compression, and ensuring reliable engine performance.

• Coolant or oil leaks around the cylinder head due to a compromised seal.
• Engine overheating, often from head gasket failure caused by improper clamping force.
• Loss of compression or misfires, resulting from a loosened or stretched head bolt.

About Genuine Porsche

The original parts used by Porsche to build your car are available as replacement parts under the “Genuine Porsche” brand. Manufactured under the direction of Porsche, expect excellent quality and a premium price since these parts are exclusively available through the Porsche Dealership network.

You may not realize this, but the parts that make up your Porsche are not necessarily manufactured by Porsche. No cause for concern, as Porsche designs the part, hires a manufacturer, and ensures its quality to you. In fact, many of these manufacturers have been making parts for Porsche for decades. In our industry these manufacturers are called OEM (Original Equipment Manufacturers), and these are often brands you recognize, including Lemforder, ZF, Sachs, Bosch, Valeo, Zimmermann, Siemens VDO, Corteco, and more. Don’t be surprised to open that Genuine Porsche parts box and find an OEM branded part inside, simply with the addition of a Porsche logo.

Be sure to keep an eye out for OE tags on our product pages to quickly identify parts coming direct from OE manufacturers. That extra bit of insight could save you some serious money while shopping! Refer to our OE Academy for further information regarding the OE/OEM tags throughout the site.
