Supertech Toyota FRS / Subaru BRZ FA20D Manganese Bronze Exhaust Valve Guide 5.5mm Stem - Set of 8

Manganese bronze is a strong material that holds up well to heat and wear, making it a solid choice for exhaust valve guides. This set from Supertech is specifically made for the FA20D engine found in the Toyota FRS and Subaru BRZ, featuring a 5.5mm stem diameter to match your existing valves.

When you're rebuilding the top end of your engine, replacing the valve guides is a critical step. These guides help ensure your valves seal properly and move smoothly within the cylinder head. The manganese bronze construction offers good lubricity and resistance to the high temperatures of the exhaust side, helping to prevent premature wear and maintain engine performance.

This is a set of eight guides, which is what you'll need for a complete engine. Make sure to check your service manual for the proper installation procedure, as valve guides typically require specialized tools and techniques to install correctly.
