Why It Matters
Valve clearance directly affects how efficiently an engine breathes and how long critical components last. Over-tight or loose valves can result in poor combustion, excessive wear, or catastrophic valve damage. The ATC 88800232 Valve Adjustment Feeler Gauge Set ensures technicians can set valve lash correctly the first time, supporting reliable engine operation and reducing the risk of costly rework.
