Supertech Honda K20 Exhaust Valve Guide 6.6mm Stem - Set of 8

Starting with a 6.6mm stem diameter, these Supertech exhaust valve guides are made to fit Honda K20 engines. Valve guides are crucial for keeping your valves moving up and down smoothly within the cylinder head, and they also help dissipate heat away from the valve head. When rebuilding or repairing the top end of your K20, ensuring you have well-made guides is key to proper sealing and engine longevity.

These guides are constructed from a durable cast iron material, chosen for its ability to withstand the heat and wear found in the exhaust port. The precise machining ensures they fit snugly into the cylinder head, preventing excessive valve wobble which can lead to poor sealing and potential damage over time. This set includes eight guides, enough for a complete engine rebuild on most K20 applications.
