TecoTek Magnetic Spark Plug Socket Set 10pc 3/8" Drive — Swivel Universal Joint, CR-V Steel, 9/16"–18mm

The TecoTek 10-piece magnetic spark plug socket set is a complete, chrome-vanadium toolkit designed to remove and install spark plugs quickly and securely using a 3/8" drive, swivel socket, universal joint and extension.

This professional-grade set groups common spark plug sizes with magnetic retention, a swivel mechanism and a durable storage case to speed jobs on cars, motorcycles, lawn equipment and small engines. Built from heat-treated Chrome Vanadium (CR-V) steel with a polished, corrosion-resistant finish, the kit balances strength and accessibility for both DIYers and pros. The included magnetic cores eliminate the need for rubber inserts and hold plugs firmly during extraction and installation.

Which spark plug sizes are included and when should I use each?

The set contains both metric and SAE sockets tailored to common vehicle and small engine spark plugs. Two 12-point swivel sockets (14mm, 16mm) and five 6-point magnetic sockets (9/16", 5/8", 3/4", 13/16", 18mm) cover most modern spark plug hexes. Use the closest matching socket size to avoid rounding the hex.

• 14mm, 16mm: common on many Asian and European engines.
• 9/16" (14mm equiv.), 5/8" (16mm equiv.): typical on American vehicles and older engines.
• 3/4", 13/16", 18mm: for larger spark plugs found on trucks, SUVs, and specialty engines.
• Swivel sockets: reach angled or recessed plugs with limited clearance.

How does the magnetic core and swivel joint make spark plug work easier?

The heavy-duty magnet in each socket securely captures the spark plug, preventing drops and minimizing fumbled installations deep in the engine bay. The swivel (universal joint) adds articulation so you can turn the socket from awkward angles without stressing the plug or ratchet.

• Magnetic retention replaces fragile rubber inserts for long-lasting grip.
• Swivel/socket articulation accesses recessed or misaligned plugs safely.
• Slim socket profile gets into tight spark plug wells without interference.
• 3/8" drive compatibility gives a balance of torque and reach with standard ratchets.

What construction and durability features protect the tools and plugs?

Each piece is made from heat-treated Chrome Vanadium steel and polished with a corrosion-resistant mirror finish, giving the set toughness for repeated shop use. The 6- and 12-point openings seat snugly on plug hexes to reduce slipping, and the magnetic core protects the porcelain and electrode during handling.

• Heat-treated CR-V steel for strength and wear resistance.
• Mirror polish finish for corrosion protection and easy cleaning.
• 6- and 12-point geometries to match different plug hex profiles.
• Magnetized core avoids rubber gasket wear and holds plugs firmly.

What accessories come with the kit and how are they organized?

The kit ships in a heavy-duty molded carrying case that keeps sockets, universal joint, extension bar and gapper organized and portable. Accessories improve usability on the job and make the set easy to store in a toolbox or vehicle.

• Universal joint for angled access to plug wells.
• 10" extension bar extends reach for deep recessed plugs.
• Spark plug gapper included for quick electrode gap checks and adjustments.
• Molded storage case keeps parts secure and easy to transport.

Who is this for? Mechanics, mobile technicians, hobbyists and vehicle owners who perform routine tune-ups and spark plug replacements will appreciate this TecoTek set. It’s designed for anyone needing reliable magnetic retention, multiple sizes and improved access in tight engine bays. The combination of CR-V construction, swivel sockets and an organized case makes it a practical, long-lasting addition to a home garage or professional toolkit.
