TecoTek Spark Plug Socket Set 11-Piece — 3/8 in Drive, 5/8–18mm CR-V Sockets with Rubber Retainers

This compact toolkit groups five popular socket sizes, a 3/8" drive ratchet, three extension bars, a universal joint and a gapper into a hard storage case so you can service spark plugs faster and with fewer lost parts. Built from chrome-vanadium steel and finished for corrosion resistance, the set is sized for passenger cars, motorcycles, lawn mowers and small engines where access and protection matter.

Which spark plug sizes are included and why they matter?

The set covers the most frequently used spark plug hex sizes so you won’t need separate sockets for common vehicles and engines. Having both metric and SAE options makes the kit versatile for older and newer engines alike.

• Includes 5/8", 3/4", 13/16", 14mm and 18mm 6-point sockets
• Sockets fit most passenger cars, light trucks, motorcycles and garden equipment
• Metric plus SAE selection reduces trips to the toolbox

How does the set protect spark plugs during removal and installation?

Each socket features an internal rubber retaining ring that cushions the plug and holds it in place while you work, reducing the chance of dropping or chipping porcelain. The 6-point socket geometry also provides a snug contact on the hex to minimize rounding and slipping.

• Rubber insert secures the plug when pulling from deep wells
• 6-point openings deliver solid grip on hex flats
• Polished finish helps plugs slide in and out without catching

What drive tools and accessories are included for tight or awkward spaces?

The kit includes a 3/8" drive ratchet plus three extensions (3", 6" and 10") and a universal joint to reach recessed plugs or work around obstacles. This combination gives you leverage and angle flexibility when space is limited.

• 3/8" ratchet provides everyday torque and control
• Extensions in three lengths for deep spark plug wells
• Universal joint enables angled access in cramped engine bays

Is this set durable and easy to organize for DIY use?

Yes. Sockets are forged from heat-treated chrome-vanadium steel with a mirror-like polish for corrosion resistance and long life. The molded storage case keeps tools sorted and each piece is stamped or labeled for quick identification.

• Heat-treated CR-V steel for strength and wear resistance
• High-visibility markings on the case and stamped tool sizes
• Compact carrying case organizes sockets, ratchet and accessories
