Bikeservice BS9134 18mm Thin Wall Spark Plug Socket Tool

The Bikeservice BS9134 is an 18mm thin wall spark plug socket engineered specifically for motorcycles, ATVs, powersports equipment, and marine applications where standard sockets simply won't fit. Its extra-thin wall bi-hex design allows access to narrow spark plug recesses that are inaccessible with conventional spark plug sockets.

Key Features:

• Thin wall bi-hex construction — designed to reach spark plugs seated in tight, narrow access holes
• Hardened chrome vanadium steel — provides durability and long-lasting performance
• Built-in rubber insert — holds the spark plug securely during installation and removal, preventing drops in hard-to-reach areas
• Dual drive compatibility — works with both 3/8 in. square drive and hex drive ratchets and extensions
• 18mm socket size — fits a wide range of motorcycle and powersports spark plugs

The BS9134 is an essential specialty tool for any motorcycle mechanic or powersports enthusiast performing spark plug service. Its thin wall profile makes it ideal for engines where clearance around the plug is minimal, while the rubber insert keeps plugs firmly seated during threading — reducing the risk of cross-threading or dropping plugs into the engine bay.
