Valve guides are crucial components that wear over time, especially with high-revving engines. To maintain proper tolerances and ensure optimal performance, it’s recommended to replace worn guides with new aftermarket ones. BC premium valve guides for the 4B11 engine are crafted from Manganese Silicon Aluminum Bronze alloy, CNC machined to precise tolerances. They offer resistance to cracking and corrosion, reduce friction, and ensure ample lubrication even at high engine temperatures and RPMs. Compatible with BC’s stainless steel valves, they are the ideal solution for worn or damaged guides.
