Part #: 3340C-14

The Koken 3340C-14 3/8" Square Drive 6-Point Universal Clip Type Spark Plug Socket is a precision-engineered tool designed for the efficient and safe removal and installation of 14mm spark plugs in professional automotive and industrial settings. This specialized universal spark plug socket combines flexible access with secure spark plug retention, making it an indispensable tool for technicians working with confined or obstructed engine compartments.

Key Features

  • Universal Joint for Enhanced Access: Engineered with a robust universal joint, this socket provides essential flexibility, allowing technicians to reach and operate on spark plugs located at angles or in tight, obstructed areas where straight sockets cannot fit.
  • Secure Spring Clip Retention: Features a unique internal spring clip system with two stainless steel clips designed to securely grip the spark plug's hexagonal part, preventing accidental drops during installation and removal.
  • Spark Plug and Thread Protection: An integrated internal brass guide ensures perfect alignment of the spark plug into the cylinder head's threaded plughole, significantly minimizing the risk of cross-threading and protecting the delicate ceramic insulator from damage.
  • Precision 14mm 6-Point Opening: The 6-point design precisely fits 14mm hexagonal spark plugs, delivering maximum surface contact for optimal torque transfer and reducing the potential for rounding off the plug's hex.

  • Optimal Reach: With an overall length of 88mm, this socket provides the necessary extension for accessing deep-seated spark plugs commonly found in modern engines.
