Valve Guide, Performance (Integrated Engineering) for B7-B8 MK5-MK6 2.0T FSI, 2.0TFSI, and 2.5L (.001" Oversized)

Using high quality valve guides in your cylinder head is essential for longevity, reliability, and performance. Integrated Engineering valve guides are designed to directly replace OEM valve guides, featuring correct outside diameter measurements to provide the ideal press-fit into your cylinder head.

Valve guides are small cylindrical bushings that press into a cylinder head, giving valves a place to reciprocate with minimal friction and wear. They facilitate valve movement and keep them perfectly centered on the valve seats. Lastly, they allow heat to transfer from the combustion chamber into the cylinder head, which is then cooled by engine coolant.

When it comes time to rebuild your cylinder head, it's very likely that you will find the OEM valve guides worn beyond wear limits. As mileage begins to add up, the inside diameter of your valve guides will wear, causing excessive clearance with the valve stems. Even on engines that have no modifications, it is common to see oil consumption, irregular valve wear, or even complete valve failure if the guides have become excessively worn.

Integrated Engineering performance valve guides work as direct OEM replacements, while offering several unique features to improve performance and increase longevity. IE valve guides are manufactured in their CNC machine shop from a proprietary bronze alloy and feature ultra-high concentricity for exact valve placement. This ensures that the head of the valve sits in the exact center of the seat, removing any possibility of leaks. Their premium alloy improves wear resistance , reduces friction, and improves heat transfer. By increasing thermal conductivity by 10%, you can expect extended valve life and reduced wear on valvetrain components. To increase airflow through the intake and exhaust ports, they have designed their valve guides with an aerodynamic tip that does not protrude into the airstream like the factory units. IE valve guides are designed to directly replace the factory guides and work well for all rebuilds, whether it be an OEM refresh or a complete race engine build!

Oversized Valve Guides:

If your cylinder head has had the valve guides replaced previously, it is recommended to confirm the inside diameter of the holes in the cylinder head before installing new guides. In some cases, the holes in the head have worn, requiring valve guides with larger outside diameters to be used. It is common practice to use oversized guides only where needed; they do not need to be used unless that particular hole is out of specification. Before installing oversized valve guides, be sure to ream the holes to the correct diameter to include the proper press-fit.

Valve Guide Undersized Inside Diameter:

All IE valve guides are sold with an undersized inside diameter. This allows the engine builder to ream the guides after installation and set the stem-to-guide clearances exactly where they need to be, since different valve materials require different clearances. This feature eliminates any guesswork associated with replacing the guides. To make installation simple, they machine a small centering lip on the tip of each valve guide, which allows them to press into the head straight and consistently.
