Supertech Audi 1.8T Manganese Bronze Intake & Exhaust Oversize Valve Guide - Set of 10

Manganese bronze is a strong material for valve guides, and this set from Supertech uses it for both intake and exhaust applications on Audi 1.8T engines. When you're rebuilding the top end of your engine, especially if you're going with an oversize valve setup, new valve guides are a critical part of the job. These guides are designed to be a direct replacement for your stock ones, but they are built to handle the demands of performance engines and potentially larger valves.

The choice of manganese bronze means these guides offer good wear characteristics, which is important for maintaining proper valve sealing and preventing premature wear. This set includes ten guides, enough for a typical 4-cylinder engine with both intake and exhaust valves covered. Proper installation is key here; they need to be pressed into the cylinder head and often require reaming to the correct size for your specific valves to ensure a perfect fit and smooth operation.
