When it comes to vehicle maintenance, changing spark plugs is a crucial task that every car owner should know how to do. A spark plug ratchet is an essential tool that makes this job much easier, especially when dealing with hard-to-reach areas or stubborn spark plugs. In this comprehensive guide, we'll dive into the world of spark plug ratchets, exploring their benefits, types, and how to use them effectively.

What is a Spark Plug Ratchet?

A spark plug ratchet is a specialized tool designed to remove and install spark plugs in an engine. It consists of a ratcheting mechanism that allows for quick and efficient rotation of the spark plug socket, making the process of removing or installing spark plugs much easier compared to using a traditional wrench.

Benefits of Using a Spark Plug Ratchet

  • Easier access to hard-to-reach spark plugs
  • Faster removal and installation process
  • Reduced risk of damaging spark plugs or engine components
  • Increased comfort and control during the job

Types of Spark Plug Ratchets

1. Standard Spark Plug Ratchet

A standard spark plug ratchet is the most basic type, featuring a simple ratcheting mechanism and a socket designed to fit most common spark plug sizes.

2. Swivel Head Spark Plug Ratchet

A swivel head spark plug ratchet offers increased flexibility, allowing the user to angle the socket head for better access to spark plugs in tight spaces.

3. Deep Well Spark Plug Ratchet

A deep well spark plug ratchet is designed with an extended socket, perfect for reaching spark plugs in deeper engine wells or those with longer threaded portions.

4. Universal Spark Plug Ratchet Set

A universal spark plug ratchet set includes multiple socket sizes and extensions, making it compatible with a wide range of spark plug types and engine configurations.

How to Use a Spark Plug Ratchet

Step 1: Identify the Correct Socket Size

Before beginning, ensure you have the correct socket size for your vehicle's spark plugs. Consult your owner's manual or use a spark plug socket sizing chart.

Step 2: Attach the Socket to the Ratchet

Securely attach the appropriate spark plug socket to the ratchet, ensuring a snug fit to prevent slippage during use.

Step 3: Locate the Spark Plug

Carefully locate the spark plug you need to remove or install. If necessary, use a swivel head spark plug ratchet or an extension to reach plugs in difficult locations.

Step 4: Remove the Spark Plug

Position the socket over the spark plug and turn the ratchet counterclockwise to loosen and remove the plug. If the plug is stubborn, apply steady pressure and use short, controlled ratcheting motions to break it free.

Step 5: Install the New Spark Plug

Place the new spark plug into the socket and position it over the engine's spark plug hole. Turn the ratchet clockwise to thread the plug into place, being careful not to over-tighten it.


What size spark plug ratchet do I need?

The size of the spark plug ratchet you need depends on the specific spark plugs used in your vehicle. Common sizes include 5/8", 13/16", and 14mm. Always refer to your owner's manual or a spark plug socket sizing chart to ensure you have the correct size.

Can a spark plug ratchet be used on all types of spark plugs?

Most spark plug ratchets are designed to work with the majority of spark plug types. However, some specialty plugs may require specific tools. It's always best to consult your vehicle's manual or a professional mechanic if you're unsure about compatibility.

How do I remove a stubborn spark plug with a ratchet?

If a spark plug is proving difficult to remove, first ensure you're using the correct socket size. Apply steady pressure and use short, controlled ratcheting motions to break the plug free. If the plug remains stuck, try using a penetrating oil to help loosen it, or consult a professional mechanic to avoid damaging the engine.
