Product Features
- 360° Swivel Action: The universal joint provides complete rotational flexibility, allowing access to spark plugs in challenging angles and tight spaces.
- Enhanced Magnetic Design: A strong magnetic core securely holds the spark plug during removal and installation, preventing accidental drops into the engine compartment, unlike traditional rubber gaskets.
- Thin Wall Construction: The low-profile design allows for smooth insertion into narrow spark plug compartments.
- Durable Material: Constructed from drop-forged, heat-treated Chrome Vanadium (Cr-V) alloy steel for increased torque and longevity.
- Corrosion Resistance: Features a fully polished, chrome-plated mirror finish for resistance against rust and corrosion, ensuring easy cleanup.
- Secure Grip: The knurled grip on the shaft provides a non-slip surface for improved handling during low torque applications.
- ANSI Standards: Designed to meet and exceed ANSI (The American National Standard Institute) standards for quality and performance.

Setup and Operating Instructions
Always ensure the engine is cool before attempting to remove or install spark plugs. Refer to your vehicle's service manual for specific spark plug replacement intervals and torque specifications.
Spark Plug Removal:
- Ensure the engine is off and cool. Disconnect the battery if necessary.
- Locate the spark plug wires or coil packs and carefully remove them from the spark plugs.
- Attach the LEXIVON 5/8" Swivel Magnetic Spark Plug Socket to a 3/8" drive ratchet or breaker bar.
- Carefully insert the socket onto the spark plug. The thin-wall design and swivel action will assist in reaching plugs in tight or angled locations.
- Turn the ratchet counter-clockwise to loosen and remove the spark plug. The magnetic core will hold the spark plug securely once it is loose, preventing it from falling.
- Lift the socket and spark plug out of the engine compartment.
Spark Plug Installation:
- Ensure the new spark plug is correctly gapped according to your vehicle's specifications.
- Place the new spark plug into the LEXIVON 5/8" Swivel Magnetic Spark Plug Socket. The magnetic core will hold it firmly.
- Carefully lower the spark plug into its port. Hand-tighten the spark plug initially to avoid cross-threading. The swivel action helps align the plug.
- Once hand-tight, use a torque wrench with the socket to tighten the spark plug to the manufacturer's specified torque. Overtightening can damage the spark plug or engine head.
- Reattach the spark plug wires or coil packs.
- Reconnect the battery if it was disconnected.
