Supertech Toyota Supra 2JZ Manganese Bronze Exhaust Valve Guide 6mm Stem OD 11.03mm - Set of 12

If you're rebuilding the top end of your Toyota Supra's legendary 2JZ engine, getting the valve guides right is crucial for proper sealing and performance. These Supertech exhaust valve guides are made from manganese bronze, a material known for its good wear resistance and ability to handle the heat of exhaust gases. They feature a 6mm stem outer diameter and a 11.03mm outer diameter, designed to fit specific applications within the 2JZ engine family.

Manganese bronze is a solid choice for exhaust valve guides because it offers a good balance of hardness and lubricity, which helps prevent valve sticking and wear. This set includes 12 guides, enough for a complete engine rebuild. Proper installation is key to ensuring these guides perform as intended, so make sure to follow the manufacturer's recommended procedures.
