What are the coil numbers?
As a car owner, it's essential to understand the various components of your vehicle, including the ignition system. One crucial aspect of this system is the coil numbers, which play a significant role in the performance of your engine. In this article, we will explore what coil numbers are, their importance, and how they affect your vehicle's operation.
What Are Coil Numbers?
Coil numbers refer to the identification numbers assigned to ignition coils in a vehicle. These coils are responsible for converting the battery's low voltage into the high voltage needed to ignite the fuel-air mixture in the engine's cylinders. Each ignition coil has a specific number that helps mechanics and technicians identify the correct part for replacement or repair.
Importance of Coil Numbers
Understanding coil numbers is vital for several reasons:
- Correct Replacement: Knowing the coil number ensures that you purchase the right ignition coil for your vehicle, preventing compatibility issues.
- Performance Optimization: Using the correct coil can enhance engine performance, fuel efficiency, and overall vehicle reliability.
- Diagnostic Assistance: Coil numbers can aid in diagnosing ignition system problems, allowing for quicker and more accurate repairs.
How to Find Coil Numbers
Locating the coil numbers in your vehicle can vary depending on the make and model. Here are some general steps to help you find them:
- Consult the Owner's Manual: Your vehicle's manual often contains information about the ignition system and coil numbers.
- Check the Ignition Coils: Open the hood and visually inspect the ignition coils. The coil number is usually printed on the coil itself.
- Use Online Resources: Websites and forums dedicated to your vehicle's make and model can provide insights and specific locations for coil numbers.
Conclusion
Coil numbers are a crucial aspect of your vehicle's ignition system, impacting performance and reliability. By understanding their significance and knowing how to locate them, you can ensure that your car runs smoothly and efficiently.

Frequently Asked Questions
Do higher ohm coils burn out faster?
All coils deteriorate eventually. If you are using a low-resistance coil at high wattages, your coil may only last 2-3 days. If you're using a higher-resistance coil at low wattages, it could last as long as two weeks.
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.
What do the numbers on a coil mean?
Resistance
Resistance is measured in “Ohms” (Ω) and on coils is most commonly a number between 0.15Ω - 2.1Ω. A higher number/resistance usually means the coil is designed to allow less power through it, whereas a lower number/resistance usually means the coil is designed to allow more power through it.
What firing order is 1-8-4-3-6-5-7-2?
See, 1-8-4-3-6-5-7-2 is the most common firing order for old V8 engines. It's used for big- and small-block Chevys and Mopars plus Buicks, Pontiacs, AMCs, most Oldsmobiles, and even DeSotos, Packards, and Studebakers. Probably more.
Are ignition coils numbered left to right?
The cylinders are 1,2,3,4 from left to right when facing the front of the car and the ignition coil is paired off 1-4, 2-3, and the firing order is 1,3,4,2.
Which ignition coil is D?
The powertrain control system (PCM) manages the ignition coils that ignite the spark plugs at precisely the right time. If the PCM detects a potential problem with the ignition coil “D” (which is the cylinder #4 ignition coil) or its circuit, code P0354 may be set.
Which is ignition coil C?
This DTC refers to an electrical problem with Ignition Coil “C” (which is the coil located at the #3 cylinder) or its circuit. The P0353 code may trigger from an issue detected from the primary (computer) side or secondary (spark plug) side of the circuit.
What are the numbers on vape coils?
Most coils will either be rated above 1 ohm or below 1 ohm. Above ohm will be any number with a 1 in front, for example, 1.2 ohm or 1.8 ohm. Anything below 1, for example, 0.6 or 0.8, is known as sub-ohm vaping as you are sub (below) 1 ohm of resistance going into the coil.
Which cylinder is number 2?
Cylinder number 2 refers not to the second cylinder in the firing order but the cylinder numbered “2” in the arrangement of cylinders on the engine. For example, on a Ford V8, the cylinders are numbered 1 to 4 on the passenger side bank and 5 to 8 on the driver side bank.
What number is ignition coil G?
The P0357 fault code can be defined as Ignition Coil “G” Primary/Secondary Circuit Malfunction. The last digit to this fault code would indicate that there is a problem which is detected within the ignition process of cylinder number 7.
