WORKPRO 14mm Magnetic Swivel Spark Plug Socket — 12" 3/8" Drive, Thin-Wall Long-Reach with 360° Swivel

WORKPRO's 14mm Magnetic Swivel Spark Plug Socket is a 12-inch, 3/8"-drive, thin-walled socket with a magnetic core and 360° swivel designed to remove and install 14mm spark plugs in tight engine bays.

This tool combines a long-reach 12" body, a one-piece rotating thin-wall socket and a built-in magnet so you can extract and seat 14mm spark plugs more securely in confined spaces. The 12-point head grips flat faces instead of corners to reduce rounding, while the knurled handle and swivel action improve control when visibility and clearance are limited. It pairs with standard 3/8" drive ratchets and extensions for routine tune-ups and roadside jobs.

How does the 360° swivel help when access is restricted?

The swivel joint lets the socket approach the spark plug at varying angles, so you don’t need a perfectly straight line from the ratchet to the plug. That flexibility makes it easier to work around manifolds, wiring harnesses and tight engine covers without disassembling surrounding parts.

• 360-degree swivel accommodates awkward angles and limited clearance
• Long 12" reach gets to deep-set plugs behind engine components
• Thin-wall profile reduces interference with nearby parts

Will this socket hold a spark plug securely during removal?

Yes — the integrated magnetic core retains the plug as you extract it, reducing the risk of dropping or damaging the porcelain. The magnet keeps the plug aligned in the socket while you guide it out of the well or back in for installation.

• Built-in magnet prevents plug loss during removal or insertion
• 12-point design grips flat faces to limit fastener round-off
• One-piece construction increases stability and reduces wobble

Is this compatible with my tools and which spark plugs fit?

The WORKPRO socket uses a standard 3/8" drive interface so it works with most ratchets, breaker bars and extensions that accept 3/8" drives. It is specifically sized for 14mm spark plugs; confirm your plug’s outer and inner diameters and available engine bay clearance before buying.

• Standard 3/8" drive fits common hand tools and extensions
• Designed for 14mm spark plugs — inner diameter ~10.8mm (0.43")
• Verify plug size and clearance in your vehicle before use

What features improve grip and reduce hand fatigue?

The socket includes a knurled handle area to improve purchase when sliding the socket by hand, and the thin-walled, balanced design requires less wrist torque in tight jobs. The 12-point head bites the flat sides of the plug for confident engagement during loosening and tightening.

• Knurled handle section improves manual grip and control
• Thin-walled body reduces interference and effort in tight spots
• 12-point head design enhances engagement and reduces slippage

Who this tool is for: Mechanics, DIY car owners and mobile technicians who regularly service ignition systems and need a long-reach, secure way to remove and install 14mm spark plugs in cramped engine compartments. If you use standard 3/8" drive ratchets and want a magnetic, swivel-enabled socket to speed plug changes while minimizing dropped plugs or damaged threads, this WORKPRO 14mm socket is built for that task. Before ordering, double-check your vehicle uses 14mm spark plugs and that a 12" socket can be maneuvered in your engine bay.
