Ko-ken 14mm 3/8" Drive Z-Series Spark Plug Socket 70mm – 6-Point, Spring Clip Retainer

Ko-ken 3300CZ-14 is a 14mm, 3/8" drive Z-Series 6-point spark plug socket with spring clips, built for secure plug removal and precise fit in tight engine bays.

This compact 70mm socket from Ko-ken’s Z-Series combines a 3/8" square drive and a 6-point head with a clip-type spring retainer so you can grab, turn, and extract spark plugs without dropping them or fighting access. Finished for durability and engineered to match factory plug profiles, the 3300CZ-14 is made for technicians and home mechanics who need a dependable tool for confined spaces and repeatable removal tasks.

How does this socket improve spark plug removal in tight spaces?

The Z-Series low-profile length (70mm) keeps the socket short enough to navigate crowded engine compartments while the 6-point geometry grips plug hexes securely. The spring clip holds the plug inside the socket so you can lift it straight out of the engine without losing it, even when working at odd angles.

• 70mm overall length for reduced protrusion in cramped bays
• 6-point opening minimizes rounding on factory plug hexes
• Spring clip retains plugs during extraction and installation
• 3/8" square drive compatible with common ratchets and extensions

What build features and compatibility should I expect from the 3300CZ-14?

Ko-ken designed this socket to match the dimensional tolerances of standard 14mm spark plugs, so fit and torque transfer are consistent. The clip-type retention and square drive interface make it compatible with a wide range of hand tools and common engine plug layouts.

• Designed for 14mm spark plug hex sizes
• 3/8" square drive for standard ratchet compatibility
• Durable finish resists corrosion in workshop environments
• Clip spring suited for reliable plug holding and release

How should I use and care for this Ko-ken spark plug socket?

Use the 3300CZ-14 with a 3/8" ratchet or extension; engage the spring clip over the plug, turn to loosen, then lift straight out to retain the plug. After use, wipe clean and store in a dry tool chest; periodic inspection of the clip for wear preserves reliable retention.

• Attach to a 3/8" drive ratchet or breaker bar for removal/installation
• Seat fully onto plug hex before applying torque to avoid slipping
• Clean and dry after use; check spring clip integrity regularly
• Use extensions or universal joints if access requires angle adaptation

Who is this for? The Ko-ken 3300CZ-14 is aimed at professional mechanics, automotive technicians, and informed DIYers who service engines with 14mm spark plugs and need a compact, secure socket for repeatable work in confined areas. If you value precise fit, dependable plug retention, and compatibility with common 3/8" drive tools, this Z-Series spark plug socket is a practical addition to your toolkit.
