Spark Plug Socket for BMW – 12 Point – Thin Walled – Flex Joint – 14mm & 16mm

BMW’s turbocharged inline-six engines bury their spark plugs in deep, narrow plug wells with surrounding obstructions that a standard plug socket will not clear. This 14mm/16mm thin-wall socket with flex joint makes plug changes on N54, N55, N20, N26, S55, N63, B46, B48, and B58 engines straightforward rather than a knuckle-scraping ordeal.

• 14mm and 16mm sizes: covers all common BMW spark plug thread sizes
• Thin-wall construction: clears the plug well without contacting the cylinder head
• Flex joint: articulates to reach plugs at angles a rigid extension cannot access
• Magnetic tip: holds the plug during extraction and insertion
• Chrome vanadium (CR-V) steel: rated for the torque spec without flex or rounding
• 12-point sleeve: engages plug hex cleanly even in low-clearance positions
