WETT Spark Plug Socket Set 12-Piece 3/8-inch Drive — Mirror-Polished Sockets with Rubber Retaining Ring

WETT 12-piece spark plug socket set is a complete, mirror-polished kit for safely removing and installing spark plugs on cars and small engines.

This compact toolkit groups five commonly used spark plug sockets, a 3/8" drive ratchet, extensions, a universal joint, adapter and a gap gauge into a durable case so you can tackle spark plug service on American, European and Asian vehicles. Every socket is made from chrome vanadium steel with a mirror chrome finish and a rubber retaining ring to protect the plug tip during removal and installation. The set is laser-etched for quick size identification and stores neatly in a high-impact carrying tray.

Which socket sizes are included and what engines do they cover?

The set contains five spark plug sockets that cover both imperial and metric sizes, making it suitable for most passenger cars, light trucks and motorcycles. Sizes include 5/8", 3/4", 13/16", 14mm and 18mm—these handle the majority of common spark plug thread diameters and reach depths.

• 5/8" and 3/4" for many domestic and older foreign vehicles
• 13/16" for select high-performance or European plugs
• 14mm and 18mm for many modern Asian and European cars
• Works on petrol engines in cars, bikes, lawn equipment and small engines

How does the kit protect spark plugs during removal?

Each socket has a rubber retaining ring that cushions the porcelain tip and keeps the plug secure inside the socket, reducing the risk of dropping or cracking plugs while removing them from tight recesses. The 6-point socket design grips the flats of the plug securely instead of biting corners, lowering the chance of rounding the hex or damaging the plug.

• Internal rubber ring stabilizes and protects the plug porcelain
• 6-point geometry reduces rounding and improves torque transfer
• Mirror-polished chrome resists corrosion and wipes clean easily
• Laser-etched size markings speed up the pick-and-use process

What accessories are included to reach recessed or angled plugs?

The kit includes three extension bars (3", 6" and 10"), a 3/8" universal joint and a 1/2" to 3/8" adapter so you can access plugs in deep wells and awkward angles. Use the universal joint and extensions with the ratchet to bend around obstructions while maintaining control and clearance.

• 3", 6" and 10" extensions for various depths
• Universal joint for angled or constrained access
• 1/2" to 3/8" adapter for tool compatibility
• 3/8" drive ratchet for smooth, controlled torque application

Is the set durable and easy to organize for storage?

Made from chrome vanadium steel with a polished chrome plating, the sockets resist wear and corrosion while delivering the strength needed for repeated use. The included high-impact storage case keeps every component in its place so you won’t lose small parts, and laser-etched size labels let you locate the right socket quickly.

• Chrome vanadium construction for strength and longevity
• Polished chrome finish for corrosion resistance and appearance
• High-impact molded case organizes and protects the tools
• Clear, laser-etched markings speed tool selection under the hood
