ELEAD 3/8" Drive 12-Piece Spark Plug Socket Set — 6 CR-V Sockets (9/16"–18mm), Ratchet & Extensions, Rubber Retention

ELEAD's 12-piece 3/8" drive spark plug socket set is a complete kit of durable CR-V sockets, ratchet, extensions, universal joint and gapper designed to remove and install spark plugs safely in tight engine spaces.

This compact toolkit groups six commonly used spark plug socket sizes with accessories that expand reach and control for passenger cars, light trucks and small engines. Constructed from heat-treated chrome vanadium steel and finished with a mirror polish, each piece resists corrosion and slips less when working in greasy or cramped engine bays. The rubber holding rings inside the sockets cushion spark plugs to minimize porcelain damage while the clear markings and molded storage case help you find the right tool quickly.

How will this set make spark plug changes faster and safer?

The combination of a 3/8" drive ratchet, three extension bars (3", 6", 10") and a universal joint lets you reach spark plugs that sit deep or at awkward angles without forcing the plug or socket. Rubber holding rings secure the plug inside the socket so it won’t fall into the manifold during removal or reinstallation.

• 3/8" ratchet handle for controlled torque and quick turnarounds
• 3", 6", 10" extensions for deep-set plugs and better access
• Universal joint for angled access to tight spark plug locations
• Rubber retention rings to protect porcelain and hold plugs securely

Which vehicles and spark plugs are covered by the included sizes?

The set contains six 6-point sockets sized 9/16", 5/8", 3/4", 13/16", 14mm and 18mm — a range that fits most domestic and import spark plugs found on cars, motorcycles, lawn equipment and many older trucks. The 6-point design reduces rounding on hex nuts and works well with stubborn or partially corroded plugs.

• 9/16" and 5/8": common on many American small engines and older cars
• 3/4" and 13/16": larger hex plugs often used in trucks or specialty engines
• 14mm and 18mm: metric sizes used widely on modern imports and motorcycles
• 6-point profile for a tighter, safer grip on plug hexes

What materials and build features ensure long-term performance?

Each socket and accessory is made from heat-treated chrome vanadium (CR-V) steel for strength under repeated use. A mirror polish finish helps resist rust and makes cleaning oil or grime easier, while the engraved or printed size markings remain visible for quick selection.

• Heat-treated CR-V steel for toughness and wear resistance
• Mirror-polish finish for corrosion resistance and easy wiping
• High-visibility size markings on sockets and storage case
• Durable molded case organizes tools and protects components

How should I use the gapper and other accessories included?

The spark plug gapper lets you verify and set the electrode gap before installation — a quick step that supports reliable ignition performance. Use the extensions and universal joint to access hard-to-reach plugs, and keep the ratchet at a steady angle to reduce stress on the plug and socket.

• Spark plug gapper for quick electrode gap checks and adjustments
• Extensions enable straight, controlled removal from deep wells
• Universal joint provides articulation for angled plug locations
• Store accessories in the case to prevent loss and organize jobs
