Supertech Audi 1.8T/2.7T Manganese Bronze Intake/Exhaust Valve Guide Oversize OD 11.075mm

These Supertech valve guides are made from manganese bronze, a material known for its excellent wear resistance and self-lubricating properties, making them a solid choice for your Audi 1.8T or 2.7T engine rebuild. They are manufactured to an oversize outer diameter of 11.075mm, which is crucial for engines that have had their valve guide bores reamed out to accommodate a larger guide. This precise sizing ensures a snug fit within the cylinder head, which is essential for proper valve sealing and engine performance.

When you're rebuilding the top end of your Audi engine, getting the valve guides right is key to ensuring the valves move smoothly and seal correctly. These guides are designed to replace your worn-out original parts, helping to restore proper valve operation and prevent issues like oil consumption or poor compression that can arise from loose or damaged guides. The manganese bronze construction offers good heat dissipation and durability, standing up well to the demands of the engine.
