Which spark plug is number one?
When it comes to car maintenance, understanding the basics of your vehicle's engine components can make a world of difference. One common question we hear at Kevin's Autos is, "Which spark plug is number one?" This question is crucial for anyone performing maintenance or troubleshooting engine issues. Let’s break it down in detail.
Understanding Spark Plug Numbering
The term "spark plug number one" refers to the first spark plug in the engine's firing order. The firing order is the sequence in which the engine's cylinders fire, and it is determined by the engine's design. Identifying the number one spark plug is essential for tasks like setting the ignition timing or diagnosing misfires.
How to Identify Spark Plug Number One
To locate the number one spark plug, follow these steps:
- Consult the Owner’s Manual: Your vehicle's owner’s manual will typically include a diagram of the engine layout and firing order. This is the most reliable source for identifying the number one spark plug.
- Locate the Cylinder Layout: Engines are designed with cylinders arranged in a specific pattern, such as inline, V-shaped, or flat. The number one cylinder is usually at the front of the engine or on the driver's side in a V-shaped engine.
- Check the Distributor Cap (if applicable): For older vehicles with a distributor, the number one spark plug wire is often marked on the distributor cap. Trace the wire to the corresponding spark plug.
- Use Online Resources: If you don’t have access to the manual, many online forums and resources provide engine diagrams for specific makes and models.
Why Knowing the Number One Spark Plug Matters
Identifying the number one spark plug is critical for several reasons:
- Setting Ignition Timing: When adjusting the ignition timing, the number one cylinder is used as a reference point.
- Diagnosing Misfires: If your engine is misfiring, knowing the firing order and the location of the number one spark plug can help pinpoint the issue.
- Replacing Spark Plugs: Properly identifying each spark plug ensures they are replaced in the correct order, avoiding confusion during maintenance.

Frequently Asked Questions
What is the code for cylinder 1?
The P0301 error code indicates that the engine control module (ECM) has detected a misfire in cylinder 1. A misfire occurs when a cylinder does not produce power, which can be due to issues with fuel, spark or compression.
What spark plug gives the most power?
Iridium spark plugs
Iridium spark plugs are the best choice. Their superior materials and construction support the high energy demands of high-performance engines and ensure the cleanest and most efficient combustion. This results in improved acceleration, better fuel efficiency, and the longest lifespan among spark plug types.
What is the number one spark plug?
The number one spark plug is always found in the number one cylinder of the engine (or the number one *rotor* in a Wankel). Look at the end of the engine closest to the accessory drive. From there, locating cylinder one is easy for any inline configuration.
What is the spark plug order on distributor cap?
The firing order on a distributor cap for an 8 cylinder engine is 1 2 3 4 5 6 7 8. Inside the distributor cap is the rotor. The rotor strangely enough got that name because it rotates. As it rotates it passes a spark though to each of the spark plug wires that are plugged into the top of the distributor cap.
What is the number 1 spark plug?
The number one spark plug is always found in the number one cylinder of the engine (or the number one *rotor* in a Wankel). Look at the end of the engine closest to the accessory drive. From there, locating cylinder one is easy for any inline configuration.
Which is number 1 on the distributor cap?
Usually they are set up with number one being the first hole to the LEFT of the hold down clip. If it doesn't run that way, move all the wires one hole to the RIGHT, so that number one is the first hole to the RIGHT of the hold down clip.
Which cylinder is number 1 on a V8?
V engine. In a V engine the frontmost cylinder is usually #1, however there are two common approaches: Numbering the cylinders in each bank sequentially (e.g. 1-2-3-4 along the left bank and 5-6-7-8 along the right bank). This approach is typically used by V8 engines from Audi, Ford and Porsche.
How are spark plugs numbered?
Number represent each part number is made up of a combination of letters. And numbers these are used to identify characteristics of the spark. Plug. With these characters.
What are the top 5 spark plugs?
Bad spark plugs undermine your engine's performance. Some of the best spark plug brands are NGK, Bosch, AC Delco, Denso, Champion, and GenuineXL. Factors you should consider when purchasing new spark plugs are the thread size, recommended use, and cost.
How to identify cylinder number 1?
On an inline engine: the number one cylinder is located at the front of the engine, closest to the timing cover. On a V type engine: one cylinder head is slightly forward of the other, toward the front of the engine. Cylinder number one is the forward most cylinder in that bank.
