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

If you're rebuilding the top end of your Toyota FRS or Subaru BRZ with the FA20D engine, these manganese bronze intake valve guides from Supertech are a solid choice. They are designed to replace the stock guides, ensuring proper valve alignment and sealing within the cylinder head. This set includes eight guides, enough for a complete engine rebuild.

Manganese bronze is a well-known material for valve guides because it offers good wear resistance and lubricity, which helps reduce friction and heat buildup. This can be especially important in performance applications where engines are pushed harder. The 5.5mm stem diameter ensures these guides are a direct fit for the specific valve stems used in the FA20D engine. Proper installation of these guides is crucial for the overall health and performance of your engine's valvetrain.
