TecoTek Spark Plug Socket Set 11-Piece — 3/8-inch Drive Ratchet, CR-V Sockets with Rubber Retainers

The TecoTek 11-piece spark plug socket set is a complete, chrome-vanadium toolkit designed for safe removal and precise installation of spark plugs across cars, lawn mowers, and small engines.

Whether you're a weekend DIYer or a professional mechanic, having the right socket size and accessories prevents stripped hexes, broken porcelain, and wasted time. This kit groups commonly used spark plug sockets with a 3/8" drive ratchet, three extension bars, a universal joint, and a gap tool in a durable case so you can reach recessed plugs and keep consistent gaps.

Which spark plug sizes and drive tools are included?

The set includes five sockets to fit popular spark plug hex sizes plus the drive and reach tools needed for most jobs. Sizes and tools are clearly marked so you can pick the right piece quickly.

• Socket sizes: 5/8", 3/4", 13/16", 14mm, and 18mm (6-point design).
• Drive and accessories: 3/8" drive ratchet handle, spark plug gapper, universal joint, and 3", 6", 10" extension bars.
• Each socket contains a rubber retaining ring to protect the plug during removal and installation.

How durable and precise are the tools?

All components are forged from heat-treated chrome vanadium (CR-V) steel with a polished finish for corrosion resistance. The 6-point socket openings reduce rounding and provide a secure fit on plug hexes.

• Heat-treated CR-V construction for strength and longevity.
• Mirror polish finish resists rust and cleans easily.
• Stamped size markings on each drive tool and printed case layout for fast identification.

How does the kit help when working in tight or recessed engine bays?

The included extensions and universal joint let you reach plugs located deep in engine heads or behind accessories. The rubber insert inside each socket retains the plug so you can extract it without dropping or chipping porcelain.

• 10" extension plus 3" and 6" bars for layered reach and leverage.
• Universal joint allows angled access where straight tools can't reach.
• Rubber retaining rings protect plugs during removal and insertion.

Who is this for? If you change spark plugs on cars, motorcycles, lawn equipment or small engines—even occasionally—this compact kit saves time and reduces the risk of plug damage. It’s suited to DIY enthusiasts, mobile technicians, and home mechanics who need an organized, corrosion-resistant set that covers common sizes and access challenges. TecoTek backs the tools with a one-year quality guarantee and ANSI-level performance, making the set a practical addition to any toolbox.
