TecoTek Spark Plug Socket Set 11-Piece — 3/8" Drive Ratchet, CR-V Sockets with Rubber Retainers (5/8", 3/4", 13/16", 14mm, 18mm)

The TecoTek 11-piece spark plug socket set is a complete, durable toolkit designed to remove, install and gap spark plugs safely and quickly across cars, lawn mowers and light engines.

This kit brings together five common spark plug socket sizes, a 3/8" drive ratchet, three extension bars, a universal joint and a gapper in a foam-lined case so you can work faster and protect delicate porcelain plugs. Every socket uses heat-treated chrome vanadium (CR-V) steel, a 6-point profile and built-in rubber retaining rings to hold plugs securely and reduce the risk of cross-threading or drop damage during removal and installation. Clear stamped markings and a printed case layout help you pick the right tool at a glance.

Which spark plug sizes are included and why do they matter?

The set covers the most frequently used spark plug hex sizes so you can service a wide range of gasoline engines without buying individual sockets. Each socket is 6-point for a precise fit and includes a rubber insert to protect the plug ceramic and electrode.

• 5/8" (16mm), 3/4" (19mm), 13/16" (20.6mm), 14mm, 18mm sizes included
• 6-point design reduces rounding and slipping on hex nuts
• Rubber retaining rings keep plugs stable during extraction

How does the ratchet, extensions and universal joint improve access?

The 3/8" drive ratchet paired with 3", 6" and 10" extensions and a universal joint lets you reach recessed or awkward spark plugs behind intake components. The universal joint adds articulation for angled entries while longer extensions give the reach needed in deeper wells.

• 3/8" ratchet for controlled torque and fit with provided sockets
• 3", 6", and 10" extension bars for shallow to deep wells
• Universal joint provides swivel access for tight, angled spaces

What materials and build details ensure durability and plug protection?

Sockets are forged from heat-treated chrome vanadium (CR-V) and finished with a mirror polish to resist rust and make cleaning easier. The 6-point profile grips flats, not corners, lowering the chance of rounding fasteners and the internal rubber rings cushion the plug during use.

• Heat-treated CR-V steel for strength and wear resistance
• Mirror polish finish for corrosion resistance and quick cleaning
• Stamped size markings and printed case layout for fast identification
