Supertech Audi 1.8T Manganese Bronze Intake/Exhaust Valve Guide Oversize OD 11.075mm - Set of 8

These Supertech valve guides are made from manganese bronze, a material known for its good wear resistance and ability to handle heat. This set includes eight guides, suitable for both intake and exhaust ports on your Audi 1.8T engine. The guides have an oversize outer diameter of 11.075mm, meaning they are designed to replace worn guides or to be installed into a reamed or honed bore that has been machined to this specific size.

When rebuilding or refreshing an Audi 1.8T engine, ensuring the valve guides are in good condition is crucial for proper valve sealing and consistent performance. Worn guides can lead to poor compression, increased oil consumption, and even valve float at higher RPMs. These Supertech guides offer a well-built replacement option, helping to restore the engine's intended operation.
