What is the purpose of a valve lash cap?

A valve lash cap sits on the end of the valve stem. Its main job is to provide a durable surface for the rocker arm or lifter to contact, preventing wear on the valve stem itself. This is especially important during engine rebuilds or performance modifications.

How do I know if my vehicle needs 5.5mm valve stems?

Many Honda, Acura, Nissan, and Toyota engines from the late 80s through the late 2000s utilize 5.5mm valve stems. It's always best to consult your vehicle's service manual or verify the valve stem diameter of your existing valves before ordering.

Are these sold individually or as a set?

This particular product, part number 42263-8, is sold as a set of 8 valve lash caps. This is typically enough for most 4-cylinder engines, but some 6-cylinder engines may require two sets.
